Circuit Breakers

A circuit breaker is an electrical device designed to protect an electrical circuit from damage caused by overload or short circuit. The LELHPK11-1RS4-31840-150-V circuit breaker is a double pole, thermal magnetic circuit breaker commonly used in household and industrial electrical systems to provide overload and short circuit protection.

Application Field

The LELHPK11-1RS4-31840-150-V circuit breaker is designed for use as a main power and control circuit breaker for industrial machinery and equipment, including industrial gas furnaces, duct heaters, welding equipment, air cleaners, furnaces and similar applications. It is also suitable for use as a branch circuit breaker in industrial and commercial buildings.

Working Principle

The LELHPK11-1RS4-31840-150-V circuit breaker combines two functions in one unit: a thermal and a magnetic trip circuit. The thermal circuit works by sensing sudden increases in temperature caused by overloads and short circuits. The built-in thermal sensors detect the increase in temperature of the circuit and trips the breaker, disconnecting the circuit and protecting it from any further damage. The magnetic trip circuit works by sensing sudden increases in current caused by short circuits and peak loads. The magnetic sensors detect the increased current in the circuit and trips the breaker, again disconnecting the circuit and protecting it from damage.

In addition, the LELHPK11-1RS4-31840-150-V circuit breaker features an adjustable trip-threshold setting. This allows users to set the breaker\'s trip-threshold at the desired level to avoid false trips due to momentary overloads. It also features an adjustable thermostat which allows users to calibrate the thermal sensing threshold of the breaker in order to ensure optimum protection for the circuit.

Maintenance

The LELHPK11-1RS4-31840-150-V circuit breaker requires minimal maintenance. In order to ensure reliable and accurate operation, users should periodically inspect and clean the contacts, and lubricate them on a regular basis with a non-conductive lubricant. Additionally, it is important to maintain an unobstructed air flow around the breaker to ensure proper ventilation and cooling, as this prevents the circuit breaker from heating up too much or tripping due to an excessively high temperature.

Conclusion

The LELHPK11-1RS4-31840-150-V circuit breaker is a reliable and highly versatile device that provides effective overcurrent and short circuit protection for a wide range of industrial and commercial applications. It features a combination of thermal and magnetic trip circuit protection, adjustable trip-threshold settings, and an adjustable thermostat which ensures optimum protection for any connected circuit. Finally, it requires minimal maintenance and should be periodically inspected and lubricated in order to ensure proper operation.
