A70P Amp-Trap® Form 101 high speed fuses were developed for higher voltage AC and DC drives, UPS systems, reduced voltage motor starters and similar applications where lower l2t and superior reliability are needed. A70P is a very popular fuse, available in a wide range of ratings. Typically used for replacement.

These Premium Amp-trap French Cylindrical Semiconductor Fuses are an extension of the popular A70QS product line. They are solid-fill 14mm and 22mm fuses IEC rated 690VAC, 200kA Interrupting and 700VDC, 100kA interrupting at 10ms time constant. In addition, these fuses have an 890 VDC rating for capacitor discharge applications up to 2.5ms time constant. All ampere ratings are available with a striker. Applications include small inverter drives and UPS systems, with superior I²t for improved protection and performance.

A70QS Amp-Trap® high speed fuses were developed in response to the need for improved overall performance of 700V semiconductor fuses for new equipment requirements. A70QS fuses have lower I2t for better protection, longer life when subjected to cyclic loading, plus lower watts loss. A70QS is the best choice to protect dynamic solid state equipment such as motor drives, UPS, etc.

Up to 250V, Time Delay, Glass, 5mm x 20mm

A15QS Amp-Trap® Form 101 high speed fuses were designed for the specific protection of diodes and other semiconductor devices rated 150VAC/DC. The A15QS product line’s compact design is perfect for those applications that have limitations on available space.

A60X Amp-Trap® Form 101 high speed fuses are popular for the protection of higher voltage heavy rectifiers such as traction rectifiers. They can carry long sustained overloads common with heavy duty apparatus. 700A through 2000A sizes are of compact, hockey-puck design, able to provide high power protection in a small space.

The NH system is classified among plug-in fuse systems and is composed of , fuse-base (possibly including terminal covers and phase barriers) , fuse-link with blade contact , fuse-link replacement device (LV HRC fuse puller) Since the design of this system cannot guarantee non-interchangeability of rated current it must be handled by a qualified professional. Type "gG" NH fuse-links are full range breaking capacity fuse-links and are used to protect cables and equipment. They can interrupt any current surge, from the lowest fusing current up to their breaking capacity, and so can be used alone as protection. They also protect electrical devices and industrial set-ups from the electrodynamic effects of very high short-circuit currents.

GFN midget indicating fuses are available in 34 ratings from 1/10A through 30A. These time-delay fuses have built-in blown fuse indicators which pop out at the end of the fuse to visually indicate when the fuse has operated. Indicators may be used to trip a switch for remote as well as visual indication. (Not for Branch Circuit Protection).

The Next Generation Power Distribution Block (PDB). Mersen power distribution blocks provide a safe and easy method of splicing cables, splitting primary power into secondary circuits and fulfilling requirements for fixed junction tap-off points. All blocks are UL and CSA approved while meeting spacing requirements for feeder and branch circuits in conjunction with UL508A and the National Electrical Code®. PDB options include single or dual conductor primary inputs and up to 30 secondary outputs. Specialty blocks are available allowing for up to 7 primary inputs. The MPDB series is offered in three size categories miniature (MPDB62 and MPDB63 series), intermediate (MPDB66 and MPDB67 series), and large (MPDB68 and MPDB69 series), in both aluminum and copper.

Mersen UltraSafe Modular Fuse holders introduce a new level of safety for Class CC (USCC) and Midget 1-1/2" x 13/32" (USM) AC and DC rated fuses up to 30 amperes. UltraSafe holders qualify as “Fingersafe” under IEC and DIN standards to an IP20 grade of protection, including fuse changing (with the flick of a finger). UltraSafe holders are available in 1, 2, 3 or 4 poles, with or without visual blown-fuse indicators in each pole. Multi-pole units can also be field assembled by ordering pin-tie handles. UltraSafe holders save up to 15% mounting space and any combination can be snapped onto 35mm DIN-rail for extra savings in panel building time. UltraSafe holders with Class CC fuses chosen for Type “2” No Damage protection give one of the safest protection packages in the industry. UltraSafe body material is tough and durable polyamide, with exceptional insulating properties.

Mersen Plug Fuses are for industrial and residential applications. Standard non-time delay fuses are for receptacle and lighting circuits. Standard time delay fuses are for motor loads. For Canadian requirements, a type “P” fuse is used for non-motor loads and type “D” fuses are used for electric heating and cycling loads circuits. Both fuses have low melting-point temperature elements. Low-Temp time delay plug fuses have thermal sensitivity are also for cycling loads and motor circuits. Type “S” plug fuses are time delay and tamper-resistant.

Mersen aM and gG fuse-links cover a wide range of physical sizes and ampere ratings for 400, 500, and 690VAC for protection in electrical distribution circuits and various industrial applications. Most ratings are available in size 8x31 and size 10x38 with an optional indicator, and in size 14x51 and 22x58 with an optional striker to activate an auxiliary contact. Size 10x38 is also available with striker. All cylindrical fuse-links have ceramic bodies and silver-plated contacts. Cylindrical fuse-links "aM" are partial range fuses. They protect electrical devices in case of unacceptable high short-circuit against destruction due high current limiting and low thermal let-through values. They cut off currents more than 6.3xln until the maximum breaking capacity (rated breaking capacity). Cylindrical fuse-links "aM" are mainly used for the protection of installation switch gear in otor circuit currents. For classification of the cylindrical fuse-links the nominal current of the fuse-link can be selected respective to the nominal current of the motor. Our technology and process was designed to ensure highly reliable technical performance.

A50P Amp-Trap® Form 101 high speed fuses were developed for DC drives, uninterruptable power supplies and similar applications requiring better protection (lower I2t) and superior reliability. The A50P is typically used for replacement.

Mersen Class H, K and R fuse blocks accommodate all Class H, K and R 250 and 600V power fuses. A choice of screw, pressure plate, box and special order stud connectors fit a wide range of stranded or solid copper or aluminum wire. Insulators are either molded glass-filled polycarbonate (GFPC) or phenolic with verified dielectric strength in excess of 2500V. 30, 60 and 100A fuse blocks feature a unique adder block which can be snapped onto 1-, 2- or 3-pole blocks to form multipole segmented blocks of as many poles as desired. All fuse clips are made of high conductivity tinplated copper, with a choice of spring reinforced or nonspring reinforced clips in 30A and 60A. Clips 100A and above are spring reinforced.

The D fuse-system is the first generation of screw fuse-systems in the German DIN standard. It is still used in many installations. This D system comprises the sizes DII, DIII, DIV, DV. Those D ultra-fast acting “gR” ranges are dedicated to semi-conductor protection, in applications where fuse-links are accessible to non-trained persons and can also be changed by them. They are used for the protection of components such as diodes, thyristors or AC/DC motor drives. The “R” stands for the English word Rectifier. D fuse-links are available at the rated current range from 2A up to 200A.

The 690/700V Protistor® fuse-links provide maximum flexibility in equipment design and ultimate protection for today's power conversion equipment. These aR ultra-fast acting square body fuse-links are available in different body sizes, each size having multiple worldwide acceptable mounting styles. The Protistor® have been engineered to provide state-of-the-art protection for semiconductors diodes, thyristors and IGBT devices. Fuses are assembled with die-cut elements embedded in solidified sand, which helps control arcing characteristics for a lower I²t and high interrupting rating level. All contact surfaces are silver plated and all hardware is non-magnetic. Each fuse-link can be equipped with a low voltage trip-indicator which can operate a field mountable microswitch.
