A circuit breaker is a device used to protect circuits from damage caused by overloads, short-circuits, and other electrical faults. In the event of a fault, the circuit breaker will automatically disconnect the circuit, protecting it from further damage. JTEP-4-2REC4-31726-18 is one such circuit breaker. This article will discuss the application field and working principle of JTEP-4-2REC4-31726-18.

Applications

JTEP-4-2REC4-31726-18 is a high performance thermal magnetic circuit breaker designed for use in residential, commercial and industrial environments. It is suitable for use in a wide range of applications, including residential, commercial, and industrial lighting, air conditioning, and electrical equipment. The circuit breaker is designed to provide protection against overcurrents, short-circuit currents, ground faults, arc annihilation, and motor overloads, up to the maximum rating of the circuit breaker. The circuit breaker is also designed to meet the requirements of UL1077, UL489A, UL198C, and IEC/EN 60947-2.

Working Principle

The working principle of JTEP-4-2REC4-31726-18 is based on the combination of thermal and magnetic tripping. The thermal part of the circuit breaker protects the circuits from overloads. This is accomplished by a bimetallic strip which expands when subjected to heat, causing the contact points of the circuit breaker to move apart and disconnecting the circuit. The magnetic tripping portion trips the circuit breaker when there is too much current flowing through the circuit, which could lead to a dangerous situation. The magnetic tripping portion is made up of an electromagnet that is energized when the current reaches a certain level, causing a plunger to move and trip the circuit breaker.

In addition to the thermal and magnetic tripping, JTEP-4-2REC4-31726-18 also has an additional built-in safety feature. This safety feature is a shunt trip, which senses when the circuit breaker has over heated. If the thermal parts of the circuit breaker sense that the temperature is too high, they will trip the circuit breaker and disconnect the circuit to avoid further damage.

Conclusion

JTEP-4-2REC4-31726-18 is a high performance thermal-magnetic circuit breaker, designed for use in residential, commercial and industrial applications. It provides protection against overcurrents, short-circuit currents, ground faults, and other electrical faults. It is also designed to meet the requirements of UL1077, UL489A, UL198C, and IEC/EN 60947-2, and it has an additional safety feature of a shunt trip which trips the circuit if the temperature is too high.
