Siemens / ITE KP3S120 – 1200A 3 Pole Molded Case Switch Last Chance

A robust solution for manual switching, the Siemens MP3S120 is a 1200A, 3-pole molded case switch. It functions purely as a non-automatic disconnect without thermal overcurrent protection. This unit mount switch is compatible with Siemens SB switchboards and S4/S5 power panelboards. For panel upgrades, it is replaced by the SND69120 electronic trip or ND63B120 breakers. It features a 600VAC maximum voltage rating and a fixed magnetic-only mechanism.
