The LELK2-30482-3-V, also commonly referred to as a circuit breaker, is a versatile and cost-effective safety device, commonly found within a wide variety of electrical distribution systems. It provides an important function in the protection of sensitive equipment, facilities and personnel by providing short-circuit, overload and other fault protection. In order to fully understand the function of the LELK2-30482-3-V circuit breaker, one must first understand its application field and working principle.

Application Field

The most common application of the LELK2-30482-3-V circuit breaker is the protection of electrical circuits. This is done by the circuit breaker detecting any abnormal amounts of current (usually greater than normal) and then quickly opening the circuit, thereby interrupting the excess current and restoring the normal functioning of the circuit. It can also detect other faults, such as shorts and ground faults, as well as protect from overvoltage, which is when a voltage level is higher than necessary. The LELK2-30482-3-V can be also used to isolate circuits for maintenance and testing. In addition, the circuit breaker is an economical solution for providing protection against loss of life and property due to short circuits, intentional overloads and other hazardous conditions.

Working Principle

The LELK2-30482-3-V circuit breaker uses an integrated system of components and mechanical elements to respond to a variety of conditions. In its most basic form, the circuit breaker includes a contact arm that opens and closes electrical circuits when it is operated by an internal solenoid or electromagnet. The contact arm is spring loaded and normally held in a “closed” position when the power is on so that electricity can flow through the circuit. But when the current exceeds the rated limit, the contact arm is moved in the opposite direction, opening the circuit and interrupting the current. The circuit breaker also includes an arc chute and other components to muffle the sound of an electrical arc and prevent the arc from causing harm. The circuit breaker also includes a pressure control switch which prevents the contact arm from closing the circuit again until the current is reduced to a safe level.

The LELK2-30482-3-V circuit breaker is a reliable, cost-effective solution for the protection of electrical circuits, offering the highest level of safety and compliance with industry standards. It is essential in providing protection from excessive current, short circuits and other hazardous conditions, thus reducing the risk of property damage, injury and loss of life.
