Thermal Overcurrent Circuit Breaker 1140-... (2-pole)
Description
Miniaturised double pole thermal circuit breaker with push-to-reset
tease-free, trip-free, snap action mechanism (R-type TO CBE to EN
60934). Threadneck panel mounting. Suitable for line and neutral
switching - the thermal actuator operating on one pole simultaneously
opens both poles under overload conditions. Approved to CBE
standard EN 60934 (IEC 60934).
Typical applications
Motors, transformers, solenoids, hand-held machines and appliances.
Especially suited to AC duties where the correct orientation of line/
neutral is not known/cannot be guaranteed.

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
