Miniaturised single pole thermal-magnetic circuit breakers with trip-free mechanism and toggle actuation (S-type TM CBE to EN 60934). Two designs provide the option of either printed circuit board or threadneck panel mounting. A separate shunt tap terminal and auxiliary contacts are available. Fast acting, medium or long delay characteristics can be specified for both models.
Suitable for use in distribution rails.
Complies with CBE standard EN 60934 (IEC 60935).

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.
