Type 4230-T (UL 1077 / EN 60947-2)

Single pole and multipole thermal-magnetic miniature circuit breakers (MCBs) in accordance with EN 60947-2 and UL 1077 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.

The 4230-T is a thermal-magnetic MCB in a standard enclosure in accordance with DIN 43880. Its conformity with the relevant standards IEC 60947-2 and UL1077 makes the 4230-T ideally suitable for worldwide use.
Due to its high rupture capacity of 63 A, the 4230-T is suitable for use as »Supplementary Protector«. Later product extensions by add-on modules such as an auxiliary contact module or a working current module offer high flexibility for the user. In addition, the device features reliable switching behaviour through a snap action  mechanism and it is positively trip-free.
