Spring-Loaded Automatic Single Phase Motor Centrifugal Switch

Spring-loaded automatic single phase motor centrifugal switch - 3 and 4 wire spring-loaded type automatic centrifugal switches for single phase motors, auto-reversing, pilot operated, complete with a single overhead momentary contact switch. Suitable for mains supply voltage up to 450 volts a.c.

The centrifugal switch is a three-phase motor protection device with spring-loaded automatic gap selection. The device has an internal lithium battery, which can provide corresponding protection to motor work in low voltage environments. Its reset button can operate the device when the power is turned on or off. It features good performance, great effectiveness and safety protection.

The centrifugal switch is designed to provide simple and reliable protection against short circuits, ground faults and overloads. It has a three position handle for manual rotation of the armature shaft.

This switch is designed for use with single-phase systems that include a motor, a thermal protector and one or more electric heaters. This switch automatically disconnects the power supply to the motor when the electric heater circuit trips. The thermal protector is located on the coil. It normally closes, but when energized it opens its contacts and allows no further current to flow through it.
