Square D TeSys Ultra Incoming Line Phase Barrier

Square D TeSys Ultra Incoming Line Phase Barrier

The Square D TeSys Ultra incoming line phase barrier is an accessory engineered for use with TeSys U power bases LUB12, LUB32, LUB38, LUB120, LUB320, and LUB380, as well as the LUALB1 limiter block. It provides complementary electrical insulation between phases at the incoming line, and is compulsory for installations on a 690V AC network and a 440V AC network. Part of the Square D TeSys Ultra range (Compatibility Code LU9), this barrier helps maintain safe phase-to-phase separation in motor starter and power base assemblies.
