Circuit Breakers

The LELPK11-31698-1-V is a type of circuit breaker designed to protect circuits from unusual or unchecked levels of current. It is most commonly seen in industrial settings, and it is employed to limit the current within a given circuit. As its name implies, it “breaks” the circuit connection when it is triggered in order to protect the system.

Application Field and Working Principle

The primary application field of the LELPK11-31698-1-V circuit breaker is to provide protection to electrical systems from overloading or short circuit conditions. When these conditions occur, the breaker trips itself, breaking the circuit that was supplying the electrical current. The breaker trips when a predetermined amperage level is exceeded, preventing further damage to any components that are connected downstream.The LELPK11-31698-1-V has three primary components which enable it to perform its protective role. The first is its heater element. This element is designed to sense the current running through the circuit, and it produces resistance when the current exceeds a set limit. The resistance heats up the element, or bimetal strip. The heat produced by the resistance causes the bimetal strip to bend, activating the circuit breaker\'s tripping mechanisms.The second component is the trip mechanism itself, which houses a pair of springs connected to the bimetal strip. As the bimetal strip bends, the springs move apart which allows the circuit breaker\'s contacts to separate and break the circuit\'s connection. The third component is the contact points, which are designed to open and close on demand. These contacts also enable the circuit breaker to be reset manually.The LELPK11-31698-1-V circuit breaker comes with a UL listed optional auxiliary contact, designed for use with alarms and indicators. This auxiliary contact is housed separately from the main contacts and can be wired independently from the main circuit breaker contact points.The LELPK11-31698-1-V is approved for use in North American households, commercial buildings and industrial settings, as well as other hazardous environments in which equipment protection is a must. It provides reliable protection from short circuits and helps prevent erratic operation of equipment and other system malfunctions due to current overloads.
