Why Choose the Mersen ATMR20 Fast-Acting Class CC Fuse?
The Mersen ATMR20 is a premium fast-acting Class CC fuse engineered to provide reliable branch circuit and overcurrent protection for industrial control circuits, machinery, transformers and electrical equipment. As part of the trusted Mersen Amp-Trap ATMR fuse series, it delivers rapid fault interruption and outstanding current-limiting performance in a compact rejection-style design.
Its rejection-style Class CC construction helps prevent incorrect fuse replacement when installed in compatible fuse holders, improving electrical safety while maintaining the intended level of circuit protection. The fast-acting characteristic rapidly clears fault currents, helping minimise equipment damage and reduce costly downtime.
With a rated current of 20 A and a 600 V AC/DC voltage rating, the ATMR20 is ideal for industrial control panels, machinery, branch circuits, control transformers and general electrical distribution. Its compact cylindrical design allows simple installation in compatible Class CC fuse holders and fused disconnect switches.
