Weidmuller CB4200 Series Supplementary Circuit Breakers Overview

Circuit breakers are necessary components of any electricity-driven network, protecting devices and machinery from damages due to overvoltage and/or overcurrent. There are several types of circuit breakers, however, with respect to the CB4200, we are concerned with the thermal-magnetic family.

Thermal-magnetic CBs are characterized by two switching mechanisms, namely an electromagnet and a bimetallic switch, with the latter serving as a means of handling over-currents. The Weidmuller CB4200 has the following major features:

The CB4200 can be mounted on 32mm or 35mm DIN-rail, making up for easy installation. The device has a trip-free design, essentially meaning that the breaker wouldn’t automatically reclose in case of a fault. Specific technical information can be referred from here.
