ATMR CLASS CC
SMALL FUSE - BIG PROTECTION
FOR GENERAL CIRCUITS
Amp-trap® ATMR fuses, in the Class CC family,
are the smallest dimension 600VAC/DC fuses suitable
for branch circuit protection. The ATMR is a popular
choice for economical protection of control circuits and
control circuit transformers where available short circuit currents exceed 10,000 amperes. ATMR’s rejection dimensions prevent substitution by lesser rated
fuses. These fast acting fuses give current limiting
protection to general circuits.
