Circuit Breakers

A circuit breaker is an electrical device designed to protect an electrical circuit from damage caused by overload or short circuit. Circuit breakers are usually either fuses or special switches that open or “trip” in response to an overload or short circuit in the circuit. The LELH11-33218-15-V is a circuit breaker specifically developed for automotive applications.

Application Field of the LELH11-33218-15-V

The LELH11-33218-15-V is designed for automotive applications such as protection against battery overloads, alternator failure, and starting motor failure. The circuit breaker offers versatile protection for both under-voltage and over-voltage conditions. It can be connected to a current sensing circuit to detect and respond to an overvoltage or under-voltage situation in the circuit. In addition, its compact size and robust construction makes it suitable for automotive applications where space is a consideration.

Working Principle of the LELH11-33218-15-V

The LELH11-33218-15-V circuit breaker operates on the principle of "thermal" interruption. The circuit breaker\'s sensing element, typically made from a bimetallic strip, is selectively and gradually heated as current passes through it. When the preset maximum is exceeded, the bimetallic strip will bend suddenly and initiate the opening of the contacts. This interrupts the circuit breaker providing protection.

The LELH11-33218-15-V has an adjustable mechanism with built-in thermal compensation to maintain a consistent trip-point for the circuit breaker. This eliminates the need for frequent trip-pointadjustments which improves safety and makes the circuit breaker more reliable. The circuit breaker also has a built-in indicator light which alerts the user when the contacts are open.

The LELH11-33218-15-V is designed to protect electrical circuits from overload and short-circuit damage. It is an ideal choice for automotive applications as it is compact and offers reliable protection. The circuit breaker has a built-in thermal compensation system and indicator light which makes it more reliable and user-friendly. The circuit breaker is designed to trip quickly and provide protection when necessary.
