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 1 and silicon rectifiers. Protection of computers and their peripheral 4230-T... equipment, industrial process control systems, telecommunications UL 489 version IEC/EN60947-2 & UL1077 version equipment, power supplies.
