Technical data
Single pole press-to-reset thermal circuit breaker with extremely fast
overload switching performance (R-type TO CBE to EN 60934). Single
hole threadneck, PCB or integral mounting with a choice of designs.
Miniaturised construction minimises PCB real estate required. Type
1410-L2 and 1410-G1 versions feature changeover contacts suitable for
providing status output signals. Largely temperature-insensitive.
Motors, transformers, solenoids, PCBs, hand-held machines, appliances,
instrumentation.
