Ordering information Technical data
Single pole thermal circuit breaker with press-to-reset, tease-free, trip-
free, snap action mechanism. Type 2-5000 is available with optional
manual release (-H), type 2-5700 can be supplied as a push-push
switch/circuit breaker (R-type TO CBE to EN 60934 in press-to-reset
configuration; M-type when fitted with manual release -H; S-type with
push-push operation). Fitted with flange or threadneck for panel
mounting. Options include an additional unprotected circuit tap (-A3).
Approved to CBE standard EN 60934 (IEC 60934).
Motors, transformers, solenoids, battery chargers, power supplies,
appliances, machinery, extra low voltage systems.
