Circuit Breakers: LELHPK111-1REC4-31219-4-V Application Field and Working Principle

Circuit breakers are electric devices that protect electric circuits and equipment in the event of an overload or short circuit. They can interrupt a short circuit of up to 10,000 Amperes. They are commonly used in domestic, commercial and industrial settings, and protect users from the risk of electric shock.

The LELHPK111-1REC4-31219-4-V is a miniature circuit breaker (MCB) and is commonly used in a variety of electrical applications. Typically, MCBs are used to protect low voltage circuits and protect both personnel and equipment. This model is used in domestic, commercial and industrial applications and is designed to provide protection against overvoltage, short circuits, and overloads.

MCBs are usually mounted in consumer units, distribution boards, and in switchgear. They come in different amperage ratings and trip current ratings. The LELHPK111-1REC4-31219-4-V has a rated voltage of 230V/50Hz, and is rated at 6A and 10A. It is suitable for protection of single-pole and double-pole circuits.

In terms of the working principle, MCBs have a manual on-off switch and two main types of action: thermal and magnetic. When the current in the system exceeds set levels, the MCB trips and disconnects the circuit. This prevents damage to the electrical components due to overload or short circuit.

Thermal action MCBs use an electromagnet connected to a bimetallic strip which is heated by the current. The bimetallic strip bends when it reaches a particular temperature and trips the breaker. Magnetic action MCBs use a solenoid which is connected to the switch. When the current exceeds a particular level, the armature of the solenoid is pulled in which trips the breaker.

In summary, the LELHPK111-1REC4-31219-4-V is a miniature circuit breaker that is used in a variety of electrical applications. It is rated at 6A and 10A and is suitable for protection of single-pole and double-pole circuits. It works by either thermal or magnetic action, depending on the type. When the current exceeds a set level, the MCB trips and disconnects the circuit.
