Powerful Circuit Protection

Choose the right Weidmuller miniature circuit breaker (MCB)*

When considering the UL 489 and UL 1077 Series MCBs, always assess the application for the following: voltage rating, maximum interrupting capacity, continuous current rating, frequency, and atypical operating conditions (ambient temperature, moisture, vibration, altitude, installation or operation orientation, and field maintenance). The MCBs are intended to protect the circuit cables as well as motors, generators and transformers, thyristors and silicon rectifiers. They also provide additional protection of computers and their peripheral equipment, industrial process control systems, telecommunications equipment and power supplies.

* Always refer to the NEC before installing any device.
