Description
Built for high-capacity applications, the Eaton HND312WK is a 3-pole, 1200A molded case switch that delivers reliable circuit isolation. It mounts into Series C panelboards, switchboards, and motor control centers. While it lacks automatic thermal protection, this N-frame disconnect includes a high instantaneous override for short-circuit safety up to 100 kAIC at 240V. The unit is supplied without terminals (WK suffix) and is replaced by the NGK3120KSE for newer Series G installations.Specifications
