Description
The Mersen ATMR8 is a fast-acting 8A Class CC fuse rated for 600V AC and 600V DC, designed to provide current-limiting branch-circuit protection and economical protection for control circuits and control circuit transformers. As part of the Amp-Trap ATMR series, this compact fuse is suitable for applications where available short-circuit currents exceed 10,000 amperes, while its rejection dimensions help prevent substitution with lower-rated fuses. The ferrule-style fuse features a tin-plated copper terminal connection and clip mounting for convenient installation.
Key Features
- 8A Fast-Acting Protection: Provides fast-acting overcurrent protection for general and control circuits.
- 600V AC/DC Rating: Rated for systems up to 600V AC and 600V DC.
- Class CC Fuse: Provides compact branch-circuit protection with rejection dimensions that help prevent substitution by lower-rated fuses.
- High Interrupting Rating: Offers a maximum AC interrupting rating of 200 kA for applications with high available short-circuit currents.
- Compact Design: Provides a small physical footprint while delivering 600V branch-circuit protection.
- Ferrule Connection: Features a ferrule terminal design with tin-plated copper connection material for reliable installation.
