Circuit breakers are essential elements in the electrical system, serving as the main protective device for personnel, equipment, and facilities. The LELK1-1REC4-31810-40-V circuit breaker is one type of circuit breaker listed as UL 1077 (Supplement SB) supplementary protectors. This particular model is a dedicated circuit breaker designed to meet stringent safety requirements and rigorous testing criteria. It is suitable for use in a wide range of applications, from residential to industrial, as well as high voltage systems.

In order to understand its past, present, and future applications, it is important to understand its construction and working principle. Its construction consists of two major components: a coil, a switch, and a trip mechanism. The coil and switch form the heart of the circuit breaker, as they are responsible for opening and closing the circuit upon an overload or short-circuit condition. The trip mechanism detects the overload or short circuit condition and triggers the switch to open the circuit, thereby disconnecting the circuit from the power supply.

As a single-pole device, the LELK1-1REC4-31810-40-V can be used in both residential and commercial settings. It can be used in UL 489 listed equipment, including motor starters, light duty switches, and motor controllers. Additionally, it can be used in UL 1077 listed applications. It is also suitable for use in high voltage systems. The voltage range for the device is 250VAC-600VAC, with an interrupting rating of 10,000A.

The most common application for the LELK1-1REC4-31810-40-V is as an auxiliary overload protector or trip unit. It is designed to detect abnormal conditions associated with overcurrent, short-circuits, and ground faults. It automatically opens the circuit when its trip time setting has been exceeded. The trip time is adjustable and can be changed to accommodate the specific requirements of the application.

The LELK1-1REC4-31810-40-V also functions as a filtering device. It can be used to limit the frequency of external electric noise which can affect sensitive equipment. It also serves as an excellent device for power factor improvement. As a result, the device can be used in a variety of applications, such as motor protection, lightning protection, motor start-up, and vari-speed drives.

The LELK1-1REC4-31810-40-V is designed to provide ultimate safety, reliability, and convenience. It can be used in a variety of applications, from residential to industrial, to meet a variety of safety and performance requirements. Its superior features, such as its adjustable trip time setting, make it an excellent choice for any application.
