Circuit Breakers

A circuit breaker is a device used to interrupt an electrical circuit when necessary, either to protect against an overload or short circuit, or to reset and start the circuit again. The JTEP-2-1-51-1-B1-400 is an example of such a device. It is a type of molded-case circuit breaker designed for protection of commercial, industrial, and residential electrical systems. This circuit breaker can be used to protect against both overload and short circuit conditions.

Application Field

The JTEP-2-1-51-1-B1-400 is a general-purpose circuit breaker with a wide range of uses. It can be used in a wide variety of applications, including commercial, industrial, and residential electrical systems. The circuit breaker also has a wide range of voltages, ranging from 220V to 440V. It is also capable of operating under a variety of different load conditions, including but not limited to single phase, three phase, and four phase.

This circuit breaker is suitable for various residential electrical systems, including HVAC systems, air conditioners, refrigerators, ceiling fans, and washers. It is also suitable for industrial applications, such as electrical and motor control panels, power switchboards, and equipment control. This circuit breaker can also be used as a protection device for various commercial installations, such as computer systems, telecommunications systems, and machinery.

Working Principle

The JTEP-2-1-51-1-B1-400 circuit breaker is based on the principle of thermal-magnetic tripping. This type of circuit breaker employs the combination of magnetic and thermal components to detect and interrupt an electrical fault. The thermal component consists of a bimetallic strip which, under normal conditions, prevents the circuit breaker from tripping. When the current flowing through the circuit becomes excessive, the bimetallic strip expands due to the Joule heating effect and causes the circuit breaker to trip to disconnect the current. The magnetic component is a solenoid-type electromagnet which creates a lifting force to open the circuit breaker contacts when the current exceeds a certain preset value.

Thermal-magnetic tripping also allows for selectivity. This means that the circuit breaker can differentiate between various overload currents, allowing it to select the appropriate circuit breaker to trip for the required application. Moreover, the circuit breaker is designed to withstand harsh environmental conditions, such as dust, humidity, and extreme temperatures. This ensures that it will function properly during a wide range of conditions.

The JTEP-2-1-51-1-B1-400 circuit breaker is an effective solution for protecting an electrical installation from overload and short circuit conditions. It is suitable for commercial, industrial, and residential applications, and can be used in a variety of conditions. Thanks to its thermal-magnetic tripping design, the circuit breaker is able to select the appropriate circuit breaker to trip for the required application. This ensures that it can provide effective protection for electrical installations from both overload and short circuit conditions.
