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.
