Schneider Electric TeSys U LUB12 Non-Reversing Power Base 12A 690V 3-Pole 5.5kW

Product Description

The Schneider Electric LUB12 is a TeSys U non-reversing power base designed for compact three-phase motor starter applications. Rated at 12 A with an operational voltage of up to 690 V AC, it supports motor loads up to 5.5 kW at 400 V when combined with a compatible TeSys U LUC control unit. The three-pole power base incorporates power contacts, a rotary operating handle, control terminals, and integrated auxiliary contacts in a compact 45 mm wide housing. Its modular plug-and-play architecture allows protection, control, and communication functions to be added according to application requirements, making it suitable for machinery, conveyors, pumps, fans, and industrial motor-control panels.
