Circuit Breakers

Circuit breakers are electrical devices designed to stop the flow of electricity in an electrical circuit when too much current passes through. The JTEP-3-1REC4-52-3-F1-500 is an example of a thermal-magnetic circuit breaker, which is commonly used in homes and commercial buildings.

Application Field

The JTEP-3-1REC4-52-3-F1-500 has a rated current of 500A, making it suitable for a range of residential, industrial, and commercial applications. Typical uses of this breaker include low- and medium-voltage automotive, welding, motor, and machine applications. This circuit breaker is also commonly used in homes and other commercial buildings to protect against overloads and short circuits.

Working Principle

The JTEP-3-1REC4-52-3-F1-500 circuit breaker is a thermal-magnetic breaker, meaning it employs both thermal and magnetic operating principles. When the breaker is triggered, a thermal element trips the breaker immediately, while a magnetic element operates more slowly to prevent extended or sustained current overloads.

When the current level passes the rated current value, the bimetallic strip on the breaker expands and trips the breaker. This trip occurs in under 1/50 of a second, providing fast protection against overloads. The magnetic element simultaneously trips the breaker after a predetermined time, preventing further damage from sustained overloads.

The ability to trip quickly and provide protection against both overloads and short circuits makes the JTEP-3-1REC4-52-3-F1-500 circuit breaker a good choice for a variety of applications, including residential, industrial, automotive, and welding.
