A50P / 500V

The A50P / 500V is part of the Mersen (formerly Ferraz Shawmut) semiconductor fuses line, distributed by Gross Automation.

A50P / 500V

A50P Amp-trap® Form 101 Semiconductor Protection 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.

Catalog Numbers

How to choose

Each catalog number is one fuse; the number spells out its choices:

  1. Amps: the Amps column (the number after A50P).
  2. Mounting: -1 is a ferrule fuse; -4 has bolt-in blades.
  3. Indicator: TI at the end adds a trigger indicator, TA a trigger actuator (integral blown-fuse indicators).

Reading a number: A50P100-4TI is rated 500 V, 100 A, bolt-in blades, with trigger indicator.
