Circuit Breakers

The LMLK1-1RS4-29172-30 is a piece of circuit breaking equipment that is designed to prevent circuits from becoming overloaded and to protect the switchgear from damage. It works by automatically disconnecting any system from the power supply when a certain level of current or voltage is exceeded.

The LMLK1-1RS4-29172-30 is a molded case circuit breaker that provides protection against both overloads and short circuits. It is rated for a maximum of 2000 Amps and a maximum of 1000 Volts. It is available in three sizes: 2-pole, 3-pole, and 4-pole. The device is also equipped with a trip indicator that can be used to provide additional protection against overloads.

The LMLK1-1RS4-29172-30 has a number of uses in commercial and industrial applications. It is commonly used as a main switch in low voltage power systems, as well as to provide overcurrent protection in high current applications. It can also be used as a branch circuit breaker in residential applications, such as for air conditioning and heating systems.

Working Principle

The LMLK1-1RS4-29172-30 operates on a thermal-magnetic operating principle. The thermal-magnetic operating principle is based on the idea that when a circuit breaker is exposed to an overload current, it will heat up. When the temperature reaches a set point, the magnetic field that is generated by the electric current causes the contacts to separate, thus disconnecting the circuit.

The LMLK1-1RS4-29172-30 also has a trip indicator that is designed to provide short-circuit protection. The trip indicator works by measuring the magnitude and instantaneous value of the current that is flowing through the circuit breaker. When the current exceeds a set level, the trip indicator triggers, which causes the contacts to open, thus disconnecting the circuit.

The LMLK1-1RS4-29172-30 also has a built-in overload protection. This overload protection is triggered when the current that is flowing through the circuit breaker exceeds a preset level. When this occurs, the contacts open and disconnect the circuit from the power supply, thus protecting the switchgear from damage.

The LMLK1-1RS4-29172-30 is UL 1066 Certified and is tested for dielectric and temperature withstand tests, as well as being tested for electrical endurance, short circuit protection, and ultimate power interruption tests. It has also been designed with built-in short-circuit protection, so it can be used safely in industrial, commercial, and residential applications.
