Thermal Overcurrent Circuit Breakers 104/105/106-...
Description
Miniaturised single pole thermal circuit breaker with push-to-reset
tease free, trip-free, snap action mechanism (R-type TO CBE to EN
60934). Available in versions for PCB or panel mounting, snap-in or
threadneck, or as an integral type. Manual release facility optional for
type 105.
Approved to CBE standard EN 60934 (IEC 60934). For higher current
ratings see type 1140.
