SHAWMUT A70P700 FUSE TYPE 4

Description:

The SHAWMUT A70P700 Fuse Type 4 is a high-speed semiconductor protection fuse designed to protect power electronic equipment from short circuits and overload conditions. Commonly installed in AC/DC drives, UPS systems, inverters, reduced-voltage motor starters, and industrial power conversion equipment requiring fast fault clearing and low let-through energy. Maintenance teams, OEMs, and system integrators use this fuse for repair, retrofit, expansion, or replacement of existing semiconductor protection devices. 

Applications:

The SHAWMUT A70P700 Fuse Type 4 is used in industrial applications requiring high-speed protection of sensitive semiconductor devices. It is commonly found in variable frequency drives (VFDs), DC drives, UPS systems, inverters, soft starters, and industrial power supplies where minimizing fault energy and protecting SCRs, diodes, IGBTs, and thyristors is essential. The Amp-Trap Form 101 series is specifically engineered for high-voltage AC and DC power electronic applications.
