Circuit Breakers

Circuit breakers are common and essential components of electrical systems. The application field and working principle of the PR11-51-25.0A-35425-25 circuitbreaker is outlined in this article.

What is a Circuit Breaker?

A circuit breaker is a device designed to protect an electrical circuit from short circuits, overloads, and other such occurrences. It works by disconnecting the circuit when it detects an abnormally high current flow. This protects both the system and the components of the circuit from being damaged.

Application Field

The PR11-51-25.0A-35425-25 circuit breaker is specifically designed for use in low voltage electrical systems. Its primary purpose is to protect against overcurrent and short-circuit fault conditions. This circuit breaker is rated for use with an AC operating voltage of 440V with a current rating of 25A.

Working Principle

The PR11-51-25.0A-35425-25 circuit breaker works in the same way as conventional circuit breakers. When it detects a fault condition, it acts to open the circuit by deactivating the contact between the two poles. This interrupts the flow of current and restores the system to a safe condition.

The circuit breaker works by monitoring the current passing through the circuit. If the current exceeds a certain threshold, the breaker trips and the contacts open, breaking the circuit. Additionally, the circuit breaker can be tripped manually by pressing a button. This allows the system to be shut down in the event of an emergency.

Maintenance Requirements

Circuit breakers like the PR11-51-25.0A-35425-25 should be regularly tested to ensure their reliability and effectiveness. The breaker should be tested approximately every 6 months. This involves measuring the current flow under both normal and fault conditions. The breaker should also be checked for any signs of damage or wear.

Conclusion

The PR11-51-25.0A-35425-25 circuit breaker is a low voltage, easily maintained circuit protection device. Its application field is for use in AC systems up to 440V and 25A and its working principle is to detect and interrupt any abnormal flow of current. As with all circuit breakers, it should be regularly tested and serviced to ensure its efficacy.
