Circuit breakers are components used to protect the electrical circuits from over currents, short circuits and overvoltage significantly. By allowing the current travelling through them to be mostly blocked, they are capable of cutting off the power supply to the investigated circuits when a certain threshold of current surpasses the imposed values. LELK1-34980-50-V is a type of circuit breaker capable of breaking an electrical circuit under a prescribed unfaulty current, usually rated between two and five times its typical full load current.

The main distinction between LELK1-34980-50-V and its counterparts is the presence of an indicator system. It features an integrated bi-stable voltage indicator to signal whether the circuit is open or closed and a thermal-magnetic indication to signal whether the circuit is overloaded or safe. The indicator system is capable of determining the up-stream status of the investigated circuits and signal them to the operator to guide him appropriately. Additionally, this circuit breaker is equipped with a built-in open-contact mechanism for adjustable short-circuit and overload protection.

The working principle of the LELK1-34980-50-V circuit breaker starts with an engine starter. It is an electromagnetic device that is capable of producing a pull force when an electrical current passes through its coils. This pull force can be used to move the contacts of the circuit breaker, thus allowing the current to be completely blocked. Until the current reaches its preset threshold, the engine starter will be working normally and the contacts of the circuit breaker will be kept closed. Once the preset threshold is met, the contacts of the circuit breaker will start to open. As soon as the contacts open, the preprogrammed electrical strength will be instantly cut off, thus preventing the further development of an unsafe situation.

The LELK1-34980-50-V circuit breakers are usually used in various industrial applications such as transport and machinery work. In these applications, they act as a safeguard in order to protect the whole system from over-currents, over-voltages and short circuits. This is particularly useful when dealing with high-risk scenarios such as large machines, as it ensures that the current flowing through the system never exceeds the preset values. As such, it is possible to reduce the risk of having an emergency situation occurring due to the failure of the electrical circuit.

To sum up, the LELK1-34980-50-V circuit breaker offers adjustable short-circuit and overload protection, as well as an integrated bi-stable voltage indicator that signals whether the circuit is open or closed. It is mainly used in various industrial applications as a tool to protect the electrical system from overcurrents, short circuits and overvoltages. By allowing the current travelling through them to be blocked, they are capable of cutting off the power supply to the investigated circuits when the preset threshold of current exceeds the imposed values.
