Circuit breakers are an essential component in many electrical systems, especially in residential and commercial setups. They are used to protect the circuit from being overloaded by either current or voltage, and to protect the user from potential electric shocks. The LELK1-1REC4-51-40.0-01-V is an example of a type of circuit breaker specifically designed for those purposes.

The LELK1-1REC4-51-40.0-01-V circuit breaker is a device that is comprised of two principal parts: a contactor and an arcing device. The contactor is a spring-loaded device that opens and closes the circuit to maintain a pre-determined level of current or voltage. The arcing device is a current- or voltage-control circuit that senses the current or voltage level and triggers the contactor in response. Once triggered, the contactor opens the circuit or parts of it, thus protecting users from electrical shocks and overload.

This particular circuit breaker is suitable for use in a range of different applications and environments. It is designed to protect circuits rated up to 40.0A, and can safely handle both alternating current (AC) and direct current (DC) of up to 277 VAC or 480 VDC. It is capable of operating at temperatures ranging from -35°C to +65°C, and is UL Recognized and CSA Certified.

In terms of working principle, the LELK1-1REC4-51-40.0-01-V circuit breaker utilizes an efficient and robust design which comprises of two principal parts: a contactor and an arcing device. The contactor opens and closes the circuit, while the arcing device is a current- or voltage-control circuit that triggers the contactor. When either the current or voltage exceeds the pre-determined threshold, the arcing device triggers the contactor, which then opens the circuit overall or parts of it, thus preventing overload and protecting the user from potentially dangerous electric shocks.

The LELK1-1REC4-51-40.0-01-V circuit breaker is therefore a reliable and efficient device that has many applications across different industries and environments. It is designed to withstand various temperature, current, and voltage levels, and to ensure that users are properly protected from any overload or shocks. As such, it is an essential component for any electrical system.
