Thermal-magnetic Miniature Circuit Breaker 4230-T...
Description
Single pole and multipole thermal-magnetic miniature circuit breakers
(MCBs) in accordance with EN 60947-2, UL 1077 and UL 489 for
DIN rail mounting, with toggle actuation, visual status indication and
high rupture capacity. A positively trip-free snap action mechanism
ensures reliable switching behaviour. A range of trip characteristics
and add-on modules allow a great variety of applications.
Typical applications
Protection of cables, motors, generators and transformers, thyristors
and silicon rectifiers. Protection of computers and their peripheral
equipment, industrial process control systems, telecommunications
equipment, power supplies.
