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.
Typical applications
Motors, transformers, solenoids, printed circuit boards, hand-held
machines and appliances, marine applications, caravans.
