Circuit Breakers

A circuit breaker is a switch designed to interrupt an electrical circuit for safety regulations or protection purposes. A circuit breaker automatically trips when a circuit exceeds the current level it can handle or when there is a short circuit that could cause damage to the system or the connected appliances. Circuit breakers can be manual or automatic and are used in both low-voltage and high-voltage components of electrical systems.

PP11S-62-15.0A-XX-C-T Application Field and Working Principle

The PP11S-62-15.0A-XX-C-T circuit breaker is a type of low-voltage device that works with a short-circuit, overload, and fault protection system. This device consists of a current transformer, thermal tripping device, and contact system.

The current transformer is responsible for constantly detecting the current flow in the circuit and adjusting its output to the thermal tripping device according to the preset limit. The output of the current transformer is in the form of a sine wave, and the amplitude of the wave is proportional to the current flowing in the circuit.

The thermal tripping device is designed to trip the circuit breaker in the event of an overload or a short-circuit. This is achieved by sensing the current passing through the transformer and then comparing it to a preset limit. If the current passing through the transformer exceeds the preset limit, then the thermal tripping device triggers the circuit breaker contact to open, thereby cutting off the supply of electricity.

The contact system is also essential for the proper functioning of the PP11S-62-15.0A-XX-C-T circuit breaker. This device consists of two contacts: one which remains open and one which stays closed. The open contact is responsible for opening the circuit and cutting off the power supply, while the closed contact is responsible for closing the circuit and restoring the power supply.

The PP11S-62-15.0A-XX-C-T circuit breaker is commonly used in residential and commercial applications, providing short-circuit, overload, and fault protection. It is also used in industrial applications to protect motors and other critical components from damage due to overload or short-circuits.
