Thermal Overcurrent Circuit Breaker 127-...
Description
Single pole thermal circuit breaker with push-to-reset, tease-free,
trip-free, snap action mechanism (R-type TO CBE to EN 60934; M-type
when fitted with optional manual release feature). Available in versions
for plug-in or integral mounting, track mounting, or with a frame for
snap-in panel mounting. The optional -KF housing is particularly suited
to high humidity and other damp conditions.
Approved to CBE standard EN 60934 (IEC 60934).
Typical applications
Motors, transformers, solenoids, battery chargers, extra low voltage
systems.
