Circuit Breakers

A circuit breaker is a device designed to protect electrical, electronic and mechanical equipment from damage caused by the abnormal flow of current. Circuit breakers are used to regulate the flow of electricity, protect from overload and short circuit, and to detect and isolate faults on the circuit. Unlike fuses, which are designed to protect from overcurrent, circuit breakers are designed to reset and are reusable.

The PR11-2-11.5A-25044-13-V is a circuit breaker that is designed to protect electrical, electronic and mechanical equipment from damage caused by the abnormal flow of current. This circuit breaker has a rated voltage of 250V and a rated current of 11.5A. The circuit breaker is a miniature breaker, meaning it is significantly smaller than regular breaker switches. In addition, this circuit breaker is designed with a thermal-magnetic trip mechanism, allowing it to safely trip with a short circuit of up to 10x rated current.

Application Field

The PR11-2-11.5A-25044-13-V circuit breaker is typically used in home and office appliances, including electric ovens, microwaves, coffee makers, and toasters. It is also used in industrial control systems and motor drives, such as elevator control systems, and industrial robots. As a miniature circuit breaker, it is also used in portable electronic devices requiring protection from overloads, short circuits and other faults. The circuit breaker is also commonly used in automotive applications, such as in electric and hybrid vehicles.

Working Principle

When the current flowing through the circuit breaker exceeds its design limit, the circuit breaker trips, interrupting the current and protecting the circuit from further damage. The PR11-2-11.5A-25044-13-V circuit breaker is a thermal-magnetic breaker which means it has two built-in protection systems. The thermal protection system is responsible for detecting excessive temperature changes that can occur when there is a high current flowing through the circuit, while the magnetic protection system detects excessive current surges.

When a high current is flowing through the circuit, the current flows through the thermal element which then burns out, disconnecting the circuit. The magnetic element also trips at a lower current, so if a short circuit occurs, the circuit breaker will immediately disconnect the circuit. If a circuit breaker is overloaded, then the magnetic element will trip after a time delay, allowing the user time to disconnect the source of the overload.

The PR11-2-11.5A-25044-13-V circuit breaker is designed to reset automatically when the overload or short circuit condition has ended. This helps to limit the down time of the circuit and hence is significantly more efficient than replacing fuses.
