Littelfuse PSR031FL0315

The PSR Flush End Series is engineered to offer high-speed protection for various power semiconductor devices, including diodes, triacs, IGBTs, SCRs, and MOSFETs. With an ampere rating of 315, these fuses are specifically designed to safeguard sensitive components in power conversion and conditioning equipment.

Typical applications include variable frequency drives, inverters, uninterruptible power supplies (UPS), rectifiers, and soft-starters, all of which require rapid protection against line surges and overcurrent conditions. The PSR Series features an interrupting rating of 200kA at 700VAC, ensuring effective circuit protection at the extremely fast response times necessary for modern technology.

These fuses are commonly utilized in a variety of industries, such as pulp and paper production, heavy-lifting equipment, processing industries, and wastewater treatment facilities, making them essential in large factories and maintenance, repair, and operations (MRO) environments. The very fast-acting (FF) opening characteristic enables immediate response to fault conditions, protecting critical equipment from damage.
