YCP5 Motor Protection Switch

YCP5 Motor Protection Switch

The YCP5 Manual Motor Protection Switch is a manually operated protective device designed for low-voltage AC motors. It combines manual switching, overload protection, short-circuit protection, and phase failure protection in a single unit. With robust mechanical construction and adjustable thermal settings, it protects motors against overcurrents and ensures safe isolation during maintenance. The switch complies with IEC/EN 60947-4-1 / IEC/EN 60947-1 standards and is suitable for industrial motor control circuits, machinery feeds, and motor starter panels.
