Circuit breakers are safety devices that are used to turn a circuit either on or off by interrupting electric current. Circuit breakers come in a variety of types and sizes for different purposes, with the most common being the LELB1-1REC5-37567-100-V type. In this article, we will discuss the application fields and working principle of the LELB1-1REC5-37567-100-V circuit breaker.

The LELB1-1REC5-37567-100-V circuit breaker is designed for use in residential, commercial, and industrial applications. It is suitable for use in single-phase, two-phase, and three-phase circuits, and can be used with either ac or dc current. The LELB1-1REC5-37567-100-V circuit breaker is capable of interrupting currents up to 100 amps in either standard or modified modes. It is rated for use at a working voltage of up to 250V and can break a circuit regardless of its current state.

The LELB1-1REC5-37567-100-V circuit breaker works by detecting an overload, short-circuit, or ground-fault in the circuit and then automatically opening the circuit to interrupt the electric current flow. This prevents damage to the circuits from overheating, fire, and other hazards. The LELB1-1REC5-37567-100-V circuit breaker features a thermal-magnetic trip system, which uses a combination of a current detector and a thermal element. The current detector measures the current flow of the circuit, and if it detects an excessive current flow, a electromagnet is activated which trips an armature to open the circuit.

The thermal element also works to remove excessive current from the circuit. The thermal element is made of a heat-sensitive material that will expand and contract based on the amount of heat within the circuit. When the circuit is overloaded and begins to heat up, the thermal element expands, which trips a switch to open the circuit.

The LELB1-1REC5-37567-100-V circuit breaker is designed for safety and reliability, with features including an overload trip indicator, an automatic reset function, and an audible trip signal. The overload trip indicator is an LED that glows red when the breaker has tripped. The automatic reset feature allows the breaker to reset itself once the current within the circuit has been reduced, while the audible trip signal alerts users to a tripped breaker.

In conclusion, the LELB1-1REC5-37567-100-V circuit breaker is a reliable and safe device that is suitable for use in residential, commercial, and industrial circuits. It features a thermal-magnetic trip system and several safety features, making it an ideal choice for protecting circuits from overcurrent, short-circuit, and ground-fault.
