TeSys U standard control unit to be inserted in power bases LUB12, LUB32, LUB38 to form a TeSys U starter controller, for 3-phase motor applications up to 1.5kW@400V. It provides full protection to motors with a rated current Ir 1.25-5A (Ir adjustable), overload tripping class 10, short circuit at 13 x Irmax, overcurrent at 14.2 x Ir, phase loss, insulation fault (protection of equipment only). To be used with a 24V AC voltage for the control of the starter (through the control terminals A1/A2 located in the power base). Certified when used in conjunction with a LUB power base (IEC, UL, CSA, CCC, EAC, Marine).
