Type 4230-T (UL 489)
Single pole and multipole thermal-magnetic miniature circuit breakers (MCBs) in accordance with EN 60947-2 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-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 UL 489 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.

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.
For most industries, the accepted norm for unplanned downtime is 5% of operating time, which represents a direct, significant loss of revenue and therefore profit. But have you ever stopped to consider the true cost of downtime? Read the latest white paper from E-T-A to see how the integration of electronic circuit control technology can reduce the downtime of your 24VDC system designs.
