Thermal Overcurrent Circuit Breaker 2-4100-...
Description
Single pole thermal circuit breaker with push-to-reset, tease-free, trip-
free, snap action mechanism (R-type TO CBE to EN 60934). Options
include an additional unprotected circuit tap (-A3) and -KF housing
particularly suited to high humidity and other damp conditions.
Designed for threadneck panel mounting.
Approved to CBE standard EN 60934 (IEC 60934).

The time/current characteristic curve depends on the ambient temperature
prevailing. In order to eliminate nuisance tripping, please multiply the circuit
breaker current ratings by the derating factor shown below. See also
