Circuit breakers are a type of device used to protect electrical circuits from damage due to overcurrent, overvoltage, or overloads. The LELK11-1-63-2.00-AF-01-V circuit breaker is a single-pole, two-pole, or three-pole circular mounted, high interrupter-rated short-term circuit protection device. It is designed for thermal-magnetic operation and rated for 125A.

The LELK11-1-63-2.00-AF-01-V is intended for indoor use in residential and small commercial applications where thermal-magnetic protection is required. The breaker is compliant with CSA Certification for Canada and UL Ratings for the United States. It is UL (Underwriters Laboratories) Listed and meets the requirements of the National Electrical Code (NEC).

The LELK11-1-63-2.00-AF-01-V circuit breaker operates in two independent modes. The first mode is the thermal-magnetic or time-delay mode. This mode senses overcurrents and shuts off power to the circuit if the amount of current exceeds the predefined settings. The time-delay feature allows the breaker to ignore momentary overloads that are common in typical residential and light-commercial applications such as reclaiming motors.

The second operating mode is the instantaneous operation or short-circuit protection. This mode is used to protect against overvoltages, short-circuits, and overloads. This mode will immediately open the circuit if the incoming current exceeds the breakers predefined settings.

The LELK11-1-63-2.00-AF-01-V circuit breaker is designed to trip only in the event of an overcurrent or overload, and is not designed to trip on a short circuit. The breaker will not open unless the overload exceeds its normal operating range. For this reason, it is important to install a correctly rated surge voltage protector, conductivity tester, or other voltage monitor devices as an additional safety measure.

The LELK11-1-63-2.00-AF-01-V circuit breaker is designed to be used in conjunction with other circuit protection devices. It should be connected between the overcurrent device and the power distribution system. Depending on the application, the breaker may also be connected to a fusing device. The breaker should be located at or near the point of use and in an area accessible for periodic testing and maintenance.

In summary, the LELK11-1-63-2.00-AF-01-V circuit breaker is a single-pole, two-pole, or three-pole circular mounted, high interrupter-rated short-term circuit protection device intended for indoor use in residential and small commercial applications where thermal-magnetic protection is required. It operates in two independent modes, the thermal-magnetic or time-delay mode for sensing overcurrents and the instantaneous operation or short-circuit protection against overvoltages, short-circuits, and overloads. It should be connected to other circuit protection devices and located at or near the point of use.
