CMB-203-11C3N-B-A Circuit Breaker

Circuit breakers are a core component of any electrical system, providing protection against overcurrents, short circuits, and ground-faults. The CMB-203-11C3N-B-A Circuit Breaker is a type of low-voltage two-pole molded-case breaker offering protection against overcurrents, short circuits, and ground-faults. It is ideal for applications in commercial, industrial, and residential settings. This article will discuss the application field and working principle of the CMB-203-11C3N-B-A circuit breaker.

Application Field

The CMB-203-11C3N-B-A Circuit Breaker is designed for use in low-voltage applications, and is suitable for use in residential, commercial, and industrial settings. It is made with two poles and can be used in either single or three-phase AC installations. It is also suitable for directly connecting to motors and other equipment with a rated voltage of up to 600V AC. The circuit breaker can be mounted on a DIN rail, wall mount panel, or floor mount panel, offering a variety of installation options.

Working Principle

The CMB-203-11C3N-B-A Circuit Breaker uses a bi-metal material to detect overcurrents. When an overcurrent is detected, the bi-metal material heats up and causes the switch contacts to open, thereby de-energizing the circuit and preventing further damage. When the overcurrent is rectified, the switch contacts close again and the circuit is re-energized.The CMB-203-11C3N-B-A Circuit Breaker also has a thermal overload device, which trips the switch in the event of a overload. When the overload device trips, it cuts off power to the load and prevents damage and injury. This thermal device is adjustable, allowing it to be adjusted to the specifics of the system.

Conclusion

The CMB-203-11C3N-B-A Circuit Breaker is an ideal choice for a variety of low-voltage applications, offering protection against overcurrents, short circuits, and ground-faults. Its bi-metal detector and adjustable thermal overload device protect the system from overloads and damages. Its versatile installation options make it suitable for a wide range of applications, from residential to commercial and industrial settings.
