Circuit breakers are the lifeblood of any power electronic system. They provide protection for shorts and overloads, and are used to prevent the spread of fires. The JLE-2-1-53-3-B1-125 is a type of circuit breaker that is used by industry professionals and can be considered the industry standard. Its unique features and robust design make it a suitable choice for many applications.

The JLE-2-1-53-3-B1-125 is a two pole, circuit breaker that is rated for 125A. It is a UL 1077 listed device that meets the requirements of UL 489 above. It is also CSA listed and tested for use in both residential and commercial applications. It has a factory mounted auxiliary contact, which can be used to control additional devices such as alarms and lights. The JLE-2-1-53-3-B1-125 also has an adjustable trip handle that allows for fine adjustment of the tripping mechanism.

The JLE-2-1-53-3-B1-125 is designed for AC and DC applications, making it a versatile choice for a number of uses. It is rated for use at 50/60 Hz and can be used up to 277 volts. The operating temperature range is -25°C to 65°C and it features a short-circuit breaking capacity of 10 kA.

The most important feature of the JLE-2-1-53-3-B1-125 is its application field and working principle. In AC circuits, the JLE-2-1-53-3-B1-125 acts as an over-current protection device. It senses and interrupts the current flow when it exceeds the set trip value. This is done via a mechanism that includes an electromagnet, a set of bimetallic strips, and a trip handle. When the current exceeds the set limit, the electromagnet pulls the trip handle which causes the bimetallic strips to bend and separate, thus interrupting the current flow.

In DC applications, the JLE-2-1-53-3-B1-125 acts as a current controlling device. This is done by using a magnetic field which fluctuates in opposition to the current. When the current exceeds the set trip value, the magnetic field will cause the trip handle to move and interrupt the current flow. This type of breaker is also more reliable in low temperature scenarios as it is less likely to trip due to thermal expansion.

This type of circuit breaker offers reliable protection from overloads and shorts and is a suitable choice for many applications. It is important to remember that any circuit breaker can be damaged if used incorrectly. Therefore, it is essential to understand the application field and working principle before installing. When done correctly, the JLE-2-1-53-3-B1-125 can provide the peace of mind and safety that are essential in all electrical installations.
