JLE-2-1REC4-36977-100 Circuit Protection

Circuit breakers are commonly used devices in many areas of electrical engineering and control engineering. They are designed to protect electrical circuits from damage due to overcurrent, short circuit, and other conditions of high electrical loads. The JLE-2-1REC4-36977-100 is a circuit breaker specifically designed for medium-voltage applications. It is an intelligent, four-pole circuit breaker that has been certified for medium-voltage applications up to 6.9 kV.

The JLE-2-1REC4-36977-100 is a thermomagnetic circuit breaker that is capable of controlling line currents of up to 7200 A at an operating temperature range of -25°C to +60°C. In addition, it offers protection for motors, feeders, and transformers and includes an electronic trip unit with adjustable operating time and current settings. This device also features a modular design, which allows for the direct addition of various components, such as motorized trip unit, harmonic filters, and phase loss protection. Moreover, this device can be used as part of a host of applications, including for remote monitoring, protection coordination, and on-site automation.

The JLE-2-1REC4-36977-100 employs a thermomagnetic tripping system. This system uses a combination of thermomagnetic and electronic principles to detect overcurrents, either caused by faults or inrush current. In the event of an overcurrent, the breaker will open its contacts, which effectively shuts off the current flow through the circuit. This system also has the capability of detecting short circuits and earth faults as well as providing protection in the event of an overvoltage. The thermomagnetic tripping system also has an adjustable current setting, which can be used to customize the breaker’s response to different levels of electrical load.

The JLE-2-1REC4-36977-100 is designed to meet a wide range of electrical needs. Its modular design allows for the direct addition of various components, such as motorized trip unit, harmonic filters, and phase loss protection. This circuit breaker is also capable of providing protection from both overcurrents and short circuits, as well as providing protection against earth faults and overvoltages. Furthermore, the adjustable current settings enable this device to be optimized for varying levels of electrical load. This makes it an ideal choice for medium-voltage applications up to 6.9 kV.
