Introduction:

Circuit breakers are safety devices used to shut off electric power in the event of a fault or overload in an electrical system. There are many different types of breakers, including the JLE-2-1-63-5-B4-250 circuit breaker, which is specifically designed for industrial and commercial applications. In this article, we will discuss the application field and working principle of the JLE-2-1-63-5-B4-250 circuit breaker.

Application field:

The JLE-2-1-63-5-B4-250 circuit breaker is designed for use in commercial and industrial facilities, including machine shops, garages, laboratories, shopping centers, hospitals, and even small businesses. The breaker is UL 1077-approved and CSA certified, making it suitable for high-power applications in areas with strict safety standards. The JLE-2-1-63-5-B4-250 is designed for use in three phase systems, and is rated for use in locations where the ambient temperature is between -5 to 55°C.

Working Principle:

The JLE-2-1-63-5-B4-250 circuit breaker is designed to work in two distinct ways - thermal (overload) and/or magnetic (short circuit). When confronted with an overload condition, the breaker trips to the “OFF” position via a bi-metallic strip which expands as the current levels increase and releases a locking mechanism. When confronted with a short circuit, the breaker trips the breaker to the “OFF” position via a separable magnetic field, which can also be released manually via the reset handle.The thermal setting of the breaker is adjustable via a dial located on the side of the breaker, allowing the user to selectively trip the breaker for specific load requirements. Furthermore, the breaker comes equipped with a built-in locking mechanism, allowing the breaker to be locked in either the “ON” or “OFF” position, preventing unauthorized tampering with the unit.The JLE-2-1-63-5-B4-250 also includes a built-in ground fault sensing feature that works in conjunction with a ground fault interrupter (GFI) to detect ground faults in the system and disconnect the circuit when an imbalance in current is detected. This feature is important for ensuring safe operations in any facility where ground faults could potentially occur.

Conclusion:

The JLE-2-1-63-5-B4-250 circuit breaker is designed to provide reliable protection from electrical overloads and shorts in commercial and industrial facilities. It is UL 1077-approved and CSA certified, designed to be used in three phase systems, and rated to operate in temperatures between -5 to 55°C. The breaker is capable of thermal and magnetic tripping with an adjustable thermal setting, and includes a locking mechanism to prevent unauthorized tampering. Additionally, the unit includes a ground fault sensing feature to detect ground faults and disconnect the circuit in a safe manner.
