Circuit Breakers: PR11-0-12.5A-XX Application Field and Working Principle

Circuit breakers are electrical switching devices that protect buildings, equipment and people from electric shock risks. They interrupt electric circuits to prevent overcurrent from causing excessive damage to wiring and electric components. The PR11-0-12.5A-XX circuit breaker is an example of a popular circuit breaker used in residential and commercial settings. This article explains the application field and working principle of PR11-0-12.5A-XX circuit breakers.

Application Field

The PR11-0-12.5A-XX circuit breaker is a dual-pole, multi-standard miniature circuit breaker with a rating of 12.5A. This circuit breaker is suitable for residential and commercial applications in buildings and electrical installations. The circuit breaker is designed to protect branch circuits that supply power to lighting, heating, air conditioning, bath facilities, air handling systems, and other large appliances. It is an ideal choice for protection of circuits in the general power network.Multi-standard circuit breakers, such as the PR11-0-12.5A-XX, are suitable for installation in many countries throughout the world. This type of circuit breaker is commonly used in countries that require different nationwide standards. Thanks to its versatile design, it can be used as an upgrade in place of other circuit breaker types in existing systems.

Working Principle

The PR11-0-12.5A-XX circuit breaker utilizes a thermal-magnetic trip. This type of circuit breaker combines two tripping elements that operate in tandem to ensure circuit protection: a thermal element and a magnetic element.The thermal trip element is activated by an increase in temperature due to operating current. This element features a bi-metal strip which, when heated sufficiently, causes the strip to bend and trip the circuit breaker. The magnetic trip element works by detecting an increase in the operating current and forcing the circuit breaker to trip. This is achieved through the use of a solenoid and an over-current release.The PR11-0-12.5A-XX circuit breaker also features a manual reset. After the circuit breaker trips due to an overcurrent, the reset switch must be manually moved to the off position to reset the trip function.

Conclusion

The PR11-0-12.5A-XX circuit breaker is a dual-pole, multi-standard miniature circuit breaker that is suitable for use in residential and commercial buildings and electrical installations. The circuit breaker features a thermal-magnetic trip, a bi-metal strip, a solenoid and an over-current release, and a manual reset switch. Thanks to its versatile design, it can be used as an upgrade in existing systems.
