Circuit breakers are a type of important switchgear used to protect electrical circuits and equipment from damage caused by overloads or short circuits. The JLE-2-39018-150 is an example of a quick-make, quick-break, dual-pole circuit breaker. This circuit breaker is designed for low voltage power distribution applications. This article will discuss the application field and working principle of the JLE-2-39018-150.

The JLE-2-39018-150 circuit breaker is a type of miniature circuit breaker (MCB), meaning it is intended for low-voltage overhead and underground distribution systems. It is suitable for use in residential, commercial, and industrial applications. Its small size and low cost make it popular for low power-consuming applications. Moreover, due to its ability to monitor and shut off power to an overloaded or short circuit, it is often used to protect circuits and equipment from potential damage.

The JLE-2-39018-150 has two connection points of contact. One contact point is a quick-make, and the other is a quick-break. The quick-make contact opens first when the overload or short-circuit occurs, and the quick-break closes after the circuit has been shut down. It is designed with an adjustable release time, so the user can set the release time to a desired duration, making it suitable for a variety of applications.

When the load on the circuit exceeds the circuit breaker’s rated current, a relay coil is activated that pushes down on the armature, which in turn trips the circuit breaker. This causes the quick-make contact to open before the quick-break contact closes, which has the effect of reducing the arc travel. This also helps contain and dissipate any sparks that might otherwise cause a fire or other hazardous event.

The JLE-2-39018-150 is designed with a built-in thermal sensor that triggers the circuit breaker when the ambient temperature rises above a certain level. This feature is intended to protect the circuit breaker from any potentially hazardous conditions that may be present. Additionally, the circuit breaker may be equipped with optional features such as an indicator light, a manual reset, and a remote reset feature.

In summary, the JLE-2-39018-150 is a type of circuit breaker designed for low voltage applications. It is equipped with a quick-make, quick-break dual-pole contact system and an adjustable release time. Additionally, it has a built-in thermal sensor for temperature sensitivity and can be equipped with optional features such as indicator lights, manual resets, and remote reset features.
