A70P / 700V
The A70P / 700V is part of the Mersen (formerly Ferraz Shawmut) semiconductor fuses line, distributed by Gross Automation.
A70P Amp-trap® Form 101 Semiconductor Protection fuses were developed for higher voltage AC and DC drives, UPS systems, reduced voltage motor starters and similar applications where lower I2t and superior reliability were needed. A70P is a very popular fuse, available in a wide range of ratings.

Catalog Numbers
How to choose
Each catalog number is one fuse; the number spells out its choices:
- Amps: the Amps column (the number after A70P).
- Mounting: -1 is a ferrule fuse; -4 has bolt-in blades.
- Indicator: TI at the end adds a trigger indicator, TA a trigger actuator (integral blown-fuse indicators).
Reading a number: A70P300-4TI is rated 700 V, style P, 300 A, bolt-in blades, with trigger indicator.
