Taian CU-18RHN-10 Contactor With Overload Relay

Description:

The Taian CU-18RHN-10 Contactor with Overload Relay is used in industrial motor control systems to start and stop three-phase AC motors while providing overload protection through the integrated RHN-10 thermal overload relay. Commonly installed in motor control centers, conveyor systems, pumps, compressors, fans, machine tools, and manufacturing equipment, it provides reliable switching and motor protection for continuous industrial operation. Maintenance teams, OEMs, and system integrators use this magnetic contactor assembly for equipment replacement, control panel assembly, and industrial automation upgrades.

Applications:

The Taian CU-18RHN-10 Contactor with Overload Relay is designed for direct-on-line (DOL) motor starting applications requiring dependable motor switching and overload protection. It is widely used in conveyors, pumps, air compressors, HVAC equipment, machine tools, packaging machinery, and industrial automation systems where reliable motor control helps improve equipment performance and reduce downtime. The CU-18 contactor is designed to operate with the RHN-10 thermal overload relay, providing integrated motor protection against overload and phase-loss conditions.
