Circuit Breakers are essential safety devices used in electrical circuits to protect against overloads and short circuits, which are possible causes of electrical fires or system damage. CELPK11-1-52-200.-21-V is a type of circuit breaker used in many different industrial applications and is a popular choice among contractors and electricians. In this article, we will explain the application field and operating principle of CELPK11-1-52-200.-21-V circuit breakers.

Applications

CELPK11-1-52-200.-21-V circuit breakers are widely used in industrial environments, due to their ability to easily handle high current loads. This type of circuit breaker is ideally suited for applications that require precise control over current or voltage and can operate reliably in harsh environments, such as extreme temperatures or a high level of vibration. CELPK11-1-52-200.-21-V circuit breakers can also be used in circuits that power motor drives, PLCs and other electrical equipment.

In addition to industrial applications, CELPK11-1-52-200.-21-V circuit breakers are suitable for use in residential, commercial and other settings. The circuit breaker can be used in both single and three-phase systems, providing reliable protection in each setup. This type of circuit breaker is also widely used in capacitor switching applications, as it can provide the necessary protection against inrush currents.

Working Principle

The CELPK11-1-52-200.-21-V circuit breaker operates using a thermal-magnetic tripping mechanism, which consists of a current sensing component and a bimetallic strip. The current sensing component measures the current flowing through the circuit, while the bimetallic strip, which is made up of two separate strips of metal, acts as a temperature sensor. When the current exceeds the pre-set limit, it causes a rapid increase in temperature in the bimetallic strip. As the temperature increases, the strips expand at different rates and this causes the switch to actuate.

The CELPK11-1-52-200.-21-V circuit breaker also includes an over-current detection coil. This coil is electronically connected to the current sensing component and rapidly increases in resistance when the pre-set current limit is exceeded. This will result in an increase in the tripping time of the breaker, allowing it to respond faster to an overload or short circuit situation and helping to protect the circuit.

Conclusion

In conclusion, CELPK11-1-52-200.-21-V circuit breakers provide an effective solution for protecting circuits against overload and short circuits. Suitable for both residential and industrial applications, the CELPK11-1-52-200.-21-V circuit breaker operates using a thermal-magnetic tripping mechanism which relies on a current sensing component and a bimetallic strip. Additionally, the circuit breaker also includes an over-current detection coil, which helps to reduce the tripping time of the breaker and to provide faster response in case of any malfunction.
