Circuit Breakers

A circuit breaker, also known as a trip switch or isolator switch, is an electrical device designed to protect an electrical circuit from damage caused by overload or short circuit while providing a permitted current flow. One of the most widely used types of circuit breakers is the CMGBX6-1RLS4-70370-15-V. This article will discuss its application field and working principle.

Application Field

The CMGBX6-1RLS4-70370-15-V is a highly reliable and cost-effective circuit breaker. It is suitable for a wide range of applications including residential, commercial, industrial, and the oil and gas industry. It is designed to protect electrical circuits from excessive current, overload, and short circuit. This circuit breaker is available in both single pole and double pole configurations, making it a versatile solution for various power distribution systems. Additionally, it has a 40A-250V voltage rating and has an adjustable instantaneous trip setting.

Working Principle

The CMGBX6-1RLS4-70370-15-V circuit breaker operates on a thermal-magnetic principle. It works by using a thermal-magnetic circuit breaker element, which is composed of two main parts: a thermal relay and a bimetal strip. The thermal relay senses any increase in current and causes the bimetal strip to expand, which then trips the circuit breaker. The thermal relay monitors the thermal properties of the current and reacts to any sudden changes in load. The bimetal strip is made of two different metals that expand and contract at different temperatures, allowing it to trip the circuit breaker when necessary.

The CMGBX6-1RLS4-70370-15-V is designed with an adjustable instantaneous trip setting, which sets the maximum allowable current limit for the breaker. When the current reaches the maximum limit, the bimetal strip will expand and cause the circuit breaker to trip before it can cause any damage. The trip setting can be adjusted depending on the load and the type of electrical system.

Conclusion

The CMGBX6-1RLS4-70370-15-V is a reliable and cost-effective circuit breaker suitable for a variety of applications. Its thermal-magnetic circuit breaker element utilizes a thermal relay and a bimetal strip to protect electrical circuits from excessive current, overload, and short circuit. Additionally, it has an adjustable instantaneous trip setting for setting the maximum allowable current limit for the breaker. The CMGBX6-1RLS4-70370-15-V is an excellent choice for any circuit breaker application.
