Circuit breakers are an essential part of electrical circuits, designed to protect against a range of voltage and current fluctuations that could lead to damage or fire. These devices are often referred to as circuit protectors and provide a level of protection from overloading and short-circuiting. The specific type of circuit breaker in question here is the CLB-203-11-B-3-A-B-A, which is designed for three-phase applications, and has a current rating of up to 125 amps.

Application Field

The CLB-203-11-B-3-7-A-B-A circuit breaker is designed to be used as an overload, short-circuit and ground fault protection device in three-phase applications. It can be used in a wide range of applications, including single and dual-phase motors, air conditioning systems, variable frequency drive inverters, pumps, water heaters, medical equipment, HVAC systems and more. Its 125 amp rating makes it suitable for most standard applications, but for larger or specialized applications it may be necessary to select a different model or size.

Working Principle

The CLB-203-11-B-3-7-A-B-A circuit breaker uses a combination of two fundamental principles for protection; these are thermal and magnetic. The thermal element responds to an overload, meaning that as the current increases, it will trip the circuit breaker and protect the connected equipment from sustained current. The magnetic element is designed to trip the circuit breaker in the event of a short-circuit, providing fast-acting protection in the event of sudden drops in voltage or current.

In order to provide ground fault protection, the circuit breaker may be used in conjunction with specialized ground fault sensors or incorporated into the breaker itself. The integrated circuit will respond to ground fault current and open the circuit breaker to protect the connected devices.

Conclusion

The CLB-203-11-B-3-7-A-B-A circuit breaker is a versatile and reliable device, providing thermal and magnetic protection for many three-phase applications. It has a 125 amp current rating, making it suitable for a range of standard electrical systems, and its integrated ground fault protection makes it an essential part of any safety system.
