Why Choose the Mersen ATMR4 Class CC Fast-Acting Fuse?
The Mersen ATMR4 is a compact and reliable Class CC fast-acting fuse designed to provide dependable branch circuit protection for industrial control panels, control circuits and control transformers. As part of the established Mersen Amp-Trap® ATMR series, it delivers rapid fault interruption and effective current-limiting protection for demanding electrical applications.
The ATMR4 features Class CC rejection dimensions that help prevent substitution with lower-rated or unsuitable fuse types. Its compact cylindrical construction saves valuable space inside electrical enclosures while providing reliable protection where available short circuit currents exceed 10,000 amperes.
With a rated current of 4 A and voltage ratings of 600 V AC and 600 V DC, the Mersen ATMR4 is suitable for industrial control circuits, automation equipment, machinery and control transformer applications requiring fast-acting overcurrent protection.
