Why Choose the Mersen ATMR12 Fast-Acting Class CC Fuse?
The Mersen ATMR12 is a compact fast-acting Class CC fuse designed to protect industrial control circuits, transformers, lighting systems and electrical equipment against short circuits and damaging overcurrents. As part of the established Mersen Amp-Trap ATMR fuse series, it provides rapid fault interruption and effective current-limiting performance for demanding industrial installations.
Its Class CC rejection-style construction helps prevent the installation of an unsuitable fuse when used with a compatible rejection fuse holder. This supports safer maintenance practices and helps ensure that the circuit retains the intended level of protection after fuse replacement.
With a rated current of 12 A and a maximum voltage rating of 600 V AC/DC, the ATMR12 is suitable for industrial machinery, control panels, auxiliary circuits and electrical distribution equipment. Its compact cylindrical format enables straightforward installation in compatible Class CC fuse holders and fused disconnect switches.
