Circuit Breakers

Circuit Breakers are an important component in an electrical circuit to protect it and the devices plugged into it. They are also known as safety switches, circuit interruptors, air circuit breakers, and fuse cutouts. Circuit breakers are designed in various sizes and types for home, office, industrial, and other purposes.LELHK11-32848-1-V is a circuit breaker with an application field of industrial usage. This circuit breaker is a thermal-magnetic type, with a rated current of 120A and a rated voltage of 400V AC-3. It is rated according to IEC/EN 60947-2 and is designed to protect a circuit against an overload or a short circuit. The LELHK11-32848-1-V is composed of a magnetic core and electromagnet coil assembly, thermoplastics enclosure, terminals, and other parts. The key components are the thermoplastics enclosure and the other parts that make up the thermal-magnetic system. The enclosure contains a variable current transformer (VCTF) and an Overload Relay with contacts. The thermoplastics enclosure also contains a tripping coil that operates a solenoid plunger, which operates the trip mechanism.The working principle of the LELHK11-32848-1-V circuit breaker is that the current through the circuit is detected by the VCTF. When the current exceeds the pre-set current level, the VCTF produces a voltage, which is then sent to the Overload Relay. The Overload Relay then contacts are opened, causing the circuit to be disconnected. On the other hand, if the current exceeds the defined current level for a prolonged period, the Overload Relay will activate the tripping coil in the thermoplastics enclosure. The tripping coil will in turn activate the plunger and trip mechanism, causing the circuit to be disconnected.In addition, this circuit breaker has a test button that can be used to manually activate the tripping mechanism. When this button is pressed, the circuit will be disconnected to check the functionality of the circuit breaker. It also has a release button to manually reset the circuit breaker after a tripping event.The LELHK11-32848-1-V circuit breaker is an important component for electrical system safety in industrial applications. It is designed to protect electrical circuits from overloading or short-circuiting, ensuring safe and reliable electrical power delivery.
