Circuit breakers are an essential part of an electrical system, providing protection against overloads and short circuits. One type of circuit breaker is the CMLHPB111-1RLS4-37029-250. This particular circuit breaker is designed to provide overload protection on single-phase three-wire systems with an instant thermal-magnetic trip system. The breaker is rated for 120/240VAC up to 50A.

The CMLHPB111-1RLS4-37029-250 circuit breaker has a wide range of applications. It is suitable for residential, commercial, and industrial applications, such as power distribution panel boards, branch circuits, motor control centers, and machine tools. In addition, the circuit breaker is rated to UL 1077, CSA 22.2, and IEC/EN 60947-2 standards, making it a reliable and safe choice.

The working principle behind the CMLHPB111-1RLS4-37029-250 circuit breaker is based on both thermal and magnetic operation. The thermal operation works by heating a bimetal strip, which then causes the circuit breaker to trip if it exceeds the rated amperage. Meanwhile, the magnetic operation works by magnetizing a metal core, which then triggers an electromagnet attached to a trip mechanism, which in turn trips the breaker should the current become too high.

The CMLHPB111-1RLS4-37029-250 circuit breaker also features a unique feature called “load limiting.” This feature works by reducing the current that the breaker can handle in the event of an overload. The load limiting feature ensures that the breaker will not overheat and cause an eventual electrical fire. As such, the load limiting feature is very useful in protecting circuits from dangerous overcurrent conditions.

Overall, the CMLHPB111-1RLS4-37029-250 circuit breaker is a reliable and safe option for providing overload protection in single-phase three-wire systems. It is suitable for a wide range of applications and is rated to UL 1077, CSA 22.2, and IEC/EN 60947-2 standards. It works by both thermal and magnetic operations, and features a unique load limiting feature which helps to protect against dangerous overcurrent conditions. As such, the CMLHPB111-1RLS4-37029-250 circuit breaker is an excellent choice for many applications.
