Description

Operating as a dedicated disconnect, the Siemens KM3S800 is a 3-pole, 800A molded case switch. Rated for 600VAC, this non-automatic unit provides manual circuit isolation without thermal overcurrent protection. The bolt-on design is compatible with Siemens P4, P5, S4, and S5 panelboards, plus motor control centers. It can be replaced by the HMD63S800 using a mounting kit. It features a rugged trip-free mechanism and magnetic-only architecture to ensure safe maintenance switching.
