Circuit Breakers

LMG1-1RLS4-40160-30 Application Field and Working Principle

Circuit breakers are electrical devices that protect electrical systems from overcurrent, short-circuit and other overload conditions. The LMG1-1RLS4-40160-30 circuit breaker is designed to protect industrial and commercial equipment and machinery from damage caused by excessive current, overload or short-circuit.

The LMG1-1RLS4-40160-30 is a single-pole, three-phase, 200 amp, Class C-frame, 480V circuit breaker. It is rated for AIC ratings of 10k, 25k or 65k. It features an adjustable overload trip range from 0.9 to 1.2 times the nominal current. The circuit breaker has a thermal-magnetic trip element for overload and ground fault protection, a current monitoring system, an electronic status indicator and a lockout/reset capabilities.

The principle of operation of a circuit breaker is based on the concept of an electrical fuse, which protects the wiring system from prolonged exposure to harmful electrical magnetic fields due to either overload or a short circuit. When an overcurrent or short-circuit condition is detected in the circuit, the circuit breaker reacts to break or trip and thus disconnect the affected portion of the circuit from the power source. The device itself de-energizes the wiring that it is connected to, preventing further damage or a potentially dangerous situation.

The LMG1-1RLS4-40160-30 circuit breaker is widely used in various industrial and commercial applications due to its reliable performance, flexibility and cost-effectiveness. It is suitable for use in circuits and equipment such as fan motors, air conditioning systems, lighting controls, appliances, and other electrical systems and components that require protection from overcurrent or short-circuit conditions. It is also often used as an alternator in stationary, portable and mobile generating sets.

The LMG1-1RLS4-40160-30 circuit breaker has a current monitoring system, which can detect and trip the breaker in the event of an overcurrent or short-circuit condition. The current monitoring system also provides protection against low-voltage faults. The device also includes an adjustable overload trip range from 0.9 to 1.2 times the nominal current, which allows the user to set the breaker to trip at the exact value that is required for the application.

The LMG1-1RLS4-40160-30 circuit breaker can also include various additional features, such as a shunt trip, which will trip the breaker in the event of an overload or ground fault condition. Another common feature is the lockout/reset capabilities, which allows the breaker to be reset after it has been tripped by the current monitoring system.

The LMG1-1RLS4-40160-30 circuit breaker is a reliable and cost-effective solution for protecting industrial and commercial machinery and equipment from damage caused by overload or short-circuit conditions. Its adjustable overload trip range, current monitoring system, lockout/reset capabilities, and other features makes it an excellent choice for any application.
