Thermal-magnetic Miniature Circuit Breaker 4230-T...
Description
Single pole and ꢁultipole therꢁal-ꢁagnetic ꢁiniature circuit breakers
(MCBs) in accordance with EN 60947-2, UL 1077 and UL 489 for
DIN rail ꢁounting, with toggle actuation, visual status indication and
high rupture capacityꢀ A positively trip-free snap action ꢁechanisꢁ
ensures reliable switching behaviourꢀ A range of trip characteristics
and add-on ꢁodules allow a great variety of applicationsꢀ
Typical applications
Protection of cables, ꢁotors, generators and transforꢁers, thyristors
and silicon rectifiersꢀ Protection of coꢁputers and their peripheral
equipꢁent, industrial process control systeꢁs, telecoꢁꢁunications
equipꢁent, power suppliesꢀ
