Furthermore, it meets Ex de IIB + H2 requirements and is rated for Class I, Zone 1, AEx de IIB + H2 T5.Constructed from copper-free aluminum, the enclosure and cover are finished with a gray epoxy powder coat for durability. Additional features include stainless steel hardware and a robust cast aluminum operating handle. Optional components such as auxiliary switches, breather/drain, and LED indicator lights can also be specified to enhance functionality.

The EDS Series factory sealed tumbler switches are specifically designed for environments classified as hazardous due to the presence of ignitable vapors, gases, or combustible dusts. These switches are particularly suitable for use in chemical and petrochemical plants, refineries, and other process industries. Constructed with a malleable iron body and covers, these switches feature a sealing chamber made from copper-free aluminum in select models. The handle is made from nylon 6/6, while the optional nameplate mounting bracket is crafted from corrosion-resistant stainless steel, providing durability and facilitating easy circuit identification without the need for costly field modifications. The switches come with a triple-coat finish comprising zinc electroplate, chromate, and epoxy powder coat, enhancing their resistance to harsh environmental conditions. They meet rigorous standards, including NEC and CEC certifications, allowing operation in Class I, Division 1 and 2 (Groups B, C, D) as well as Class II and III environments.

The Unicode 2 Series 16 Amp switches are engineered for enhanced safety in industrial applications. These switches facilitate circuit control and selection, making them ideal for integration with contactors or magnetic starters for motor management. With compliance to NEC, CEC, ATEX, and IECEx standards, the devices are rated for Class I, Division 2 and Zone 1 environments, ensuring reliable operation in hazardous conditions. Constructed with a polyamide body and silver alloy contacts, these switches operate effectively across a broad temperature range, from -55 °C to +80 °C (-67 °F to +176 °F) for both NEC and CEC environments, as well as ATEX and IECEx specifications. Handles are rated for -20 °C to +55 °C (-4 °F to +131 °F), providing durability and functionality in various operational settings.

The AE Series Disconnect Switches, designated as PN AEAB6036DS, are designed to ensure safety in areas where hazardous materials are present. These switches offer both fused and non-fused options for overload and short circuit protection, as well as control for lighting and power circuits.Constructed with copper-free aluminum bodies and covers, these units feature stainless steel disconnects, operator shafts, cover bolts, and hinges, combined with a neoprene O-ring for enhanced sealing. The enclosure and cover are coated with gray epoxy powder both inside and outside, achieving a NEMA 4X rating, suitable for harsh environments.The units are compliant with NEC certifications, specifically for Class I, Division 1 and 2, Groups B, C, D; Class II, Division 1 and 2, Groups E, F, G; and Class III. Additional options include auxiliary switches, breather, drain, external grounding stud, and plastic nameplate for customization.

The nonmetallic tumbler switch, identified as PN N1DC75F3W, is specifically engineered to mitigate the risk of arcing in environments where flammable gases, vapors, or combustible dust may be present. This switch is suitable for use in various industrial settings, including chemical and petrochemical plants, as well as refineries.Constructed from 30% glass-reinforced thermoplastic polyetherimide, the switch features Teflon™ coated stainless steel cover bolts and Mylar™ nameplates, ensuring durability and resistance to corrosion. The design includes a nameplate mounting bracket that simplifies the identification of circuits, eliminating the need for field modifications such as drilling or tapping.This unit meets stringent safety standards, certified under NEC for Class I, Division 1 and 2, Groups C and D, and NEMA ratings of 3R, 4X, 7CD, and 12, ensuring reliable performance in demanding conditions.

The DBR 30, 60, 100 and 150 Amp Series Receptacles are designed for hazardous environments, offering both interlocked circuit breakers and disconnect switches for safety. These receptacles ensure reliable operation in Class I, Division 1 and 2, Groups B, C, D, as well as Class II, Division 1 and 2, Groups F, G environments, complying with NEMA ratings 3, 3R, 4, 4X, 7CD, and 9FG.The integrated interlocked circuit breaker not only allows for connect and disconnect capabilities but also provides essential protection against short circuits and thermal overloads, thus safeguarding connected equipment from damage. In contrast, the disconnect switch ensures safe handling during maintenance and operation.With various options available for amperage (30, 60, 100, or 150), voltage (120/240/480/600 Vac or 250 Vdc), and configurations of poles and wires, these receptacles are versatile. They support horsepower ratings from 1 to 75 and accommodate plug cable diameters ranging from .500 to 2.187 inches. Constructed from copper-free aluminum and reinforced polyester, these receptacles ensure durability and longevity in demanding applications.
