JLE-3-1-63-5-B4-175 Circuit Protection

Introduction

JLE-3-1-63-5-B4-175 is a type of circuit breaker, also known as an electric switch, that is used to protect electrical circuits from overcurrent, overvoltage, or overload conditions. Circuit breakers are typically used in low-voltage systems, especially with residential applications. They are designed to be electrically operated and manually operated, and can be either a single-pole or double-pole design.

Application field

JLE-3-1-63-5-B4-175 circuit breakers are primarily used in low-voltage systems, such as those found in commercial and residential buildings. They are used to disconnect the power supply to an electrical circuit or appliance in the event of an overcurrent, overvoltage, or overload condition. They are typicallyinstalled in a switchboard, distribution board, service panel, or load centre.

Working Principle

When an overcurrent, overvoltage, or overload condition is detected, the JLE-3-1-63-5-B4-175 circuit breaker will trip and, either mechanically or electronically, open the circuit. The trip action of the breaker is triggered by a thermal element in the circuit breaker that will expand when the current or voltage reaches a set level, triggering the breaker to trip. This will cause the electrical contacts in the circuit breaker to open, thus preventing any further current from flowing through the circuit.

In addition to providing overcurrent, overvoltage, and overload protection, the JLE-3-1-63-5-B4-175 circuit breaker may also provide other protective functions, such as short-circuit protection and ground-fault protection. Short-circuit protection is designed to trip the breaker if the current exceeds a certain amount, while ground-fault protection is designed to trip the breaker when the current between the live conductor and the earth is greater than a set value. The overload protection is necessary to protect the circuit from being overloaded or from too much current being consumed by the circuit.

Conclusion

The JLE-3-1-63-5-B4-175 circuit breaker is an important safety device for low-voltage electrical systems. It is designed to automatically and instantly protect the electrical circuit from overcurrent, overvoltage, or overload conditions. This breaker can provide short-circuit and ground-fault protection in addition to overload protection, making it a versatile and useful device in many low-voltage applications.
