Circuit breakers are electrical devices used to protect circuits against overcurrent, undercurrent and/or short-circuit conditions. They serve a critical safety purpose in helping to protect circuits and systems that are used in a variety of applications. The CMB-103-27G3N-B-A Circuit Breaker is a type of molded-case circuit breaker (MCCB) that offers a high level of protection against overcurrent and short-circuit conditions.

The CMB-103-27G3N-B-A offers an unprecedented level of customization and performance within a power circuit breaker. The CMB-103-27G3N-B-A is designed to provide optimal protection in applications requiring reliable and maintenance-free performance. It is suitable for applications in industrial and commercial facilities, power distribution systems, heating, ventilation and air conditioning (HVAC) systems, and process control systems.

The CMB-103-27G3N-B-A is built with a trip unit system with many features such as manual reset, thermal magnetic trip element, phase balancing, neutral balancing, adjustable short-time delay and adjustable instantaneous trip off. The trip unit system provides complete power protection with high short-circuit current ratings, adjustable installation trip curves and adjustable ground fault current settings. This offers the CMB-103-27G3N-B-A maximum flexibility with a wide range of applications.

The CMB-103-27G3N-B-A’s enclosure is designed for use in indoor and outdoor installations. The contact housing and bushings are designed for enhanced contact reliability that helps to prevent arcing and provide superior short-circuit protection. The CMB-103-27G3N-B-A also offers an optional external contact position indicator which provides visual indication of the breaker’s status.
