Product Description

Application

LC1-D series AC contactors (hereinafter referred to as simplified AC contactors) are suitable for 50Hz or 60Hz power supply frequencies, with rated voltages up to 660V and rated currents up to 95A. This type of contactor is mainly used for remote control circuit connection and disconnection, and can frequently start and stop AC motors to meet the needs of industrial automation and electrical control systems.

The design of the LC1-D series contactor enables it to be used in combination with accessories such as auxiliary contact groups, air delay devices, and mechanical interlocking devices to form a time-delay contactor. This combination not only improves the flexibility of the circuit, but also enhances the safety and reliability of the system. The mechanical interlocking contactor can be used in combination with a star-delta starter and a thermal relay to form the mechanical structure of an electromagnetic starter. This configuration can effectively reduce the starting current during the motor starting process, extend the service life of the equipment, and improve the operating efficiency of the overall system.

LC1-D series AC contactors are widely used in various industrial equipment and automation systems due to their high performance and versatility, providing a reliable solution for electrical control.
