Type: 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.

The 4230 is a thermal-magnetic MCB in a standard enclosure in accordance with DIN 43880. Its conformity with the relevant standards IEC 60947-2, UL1077 and UL 489 makes the 4230-T ideally suitable for worldwide use.
Due to its high rupture capacity of 63 A, the 4230 is suitable for use as »Branch Circuit Protection« and also 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.

Differences and Similarities Between K Curve and D Curve Breakers

A Miniature Circuit Breaker (MCB) is a resettable protective device that prevents electrical circuits from catching fire and causing damage to personnel and property. It is a device designed to isolate a circuit during an overcurrent event without using a fusible element. There are two types of overcurrent events; a thermal overload and a short circuit.
