LELK11-1REC4-38878-100-V Circuit Protection

Circuit Breakers

Circuit breakers are essential elements of any electrical circuit; as electrical current passes through them, the circuit breaker either interrupts this current completely or diverts it to another circuit. The specific circuit breaker model designated LELK11-1REC4-38878-100-V is an electromagnetic motor circuit-breaker and is typically used to protect low-voltage power equipment and circuits, preventing electric shocks and fire hazards from occurring. It is classified as a 3-pole circuit breaker with a breaking capacity of 10kA at a 240V AC line voltage.

An electromagnetic motor circuit breaker uses a magnetic field to act as an impulse switch that operates an internal switch mechanism. It protects the circuit by interrupting the electric current when it becomes too excessive. This is done with the help of a solenoid actuator which moves with an energy release function. A fragment of a magnetic field created by a small current in the solenoid actuator coil is stored energy and unleashed, opening the contact points when the current becomes too strong.

The contacts of a motor circuit breaker are designed to operate with a load that carries a variable current. As the current passes through it, two small contact points, or blades, move away from each other, breaking the circuit. When the current drops again and the load is no longer energized, the two blades return to their original position. This re-closing action takes place only if no damage has occurred to the contacts due to the high current.

The LELK11-1REC4-38878-100-V model circuit breaker is designed for indoor installation in panels and switchboards up to a maximum voltage of 600V AC and 250V DC.

The circuit breaker can be used in a variety of applications, including power distribution systems, motor control centers, industrial machinery, HVAC systems, electrical drives, and lighting systems.

The LELK11-1REC4-38878-100-V model is packaged with an extensive array of features to ensure maximum safety and protection. These features include adjustable current protection trip settings, Overcurrent Protection (OCP) technology, and voltage surge protection. It also has the ability to detect and inhibit inrush currents, and can be equipped with sensors to monitor circuit temperature.

The LELK11-1REC4-38878-100-V model has a high fault-withstanding capacity, making it suitable for a wide range of industrial and commercial applications. Additionally, the circuit breaker is capable of accommodating heavy loads, resisting short circuits and voltage transients, and is energy-efficient. Once installed, the breaker can be used for 12 to 18 months before it needs to be replaced.

The LELK11-1REC4-38878-100-V motor circuit breaker is designed to protect electrical circuits from damage due to overloads and short circuit faults. It is suitable for a variety of commercial and industrial applications, and is a reliable and energy-efficient solution to ensure the safe operation of electrical circuits.
