Thermal Overcurrent Circuit Breaker 1657-...
Description
Single pole thermal reset circuit breaker in a miniaturised design
intended for thread neck mounting. Easy and quick reset after
tripping due to overcurrent. Trip-free mechanism and automatic
disconnection in the event of an overcurrent, even with a blocked
actuator button. R-Type TO CBE to EN60934. Very cost effective
design to meet international requirements.
l Manual reset, trip free mechanism
l Extremely small and lightweight
