TeSys U control and diagnostic unit to be inserted in advanced power bases LUB320, LUB380 to form a TeSys U starter controller, for 3-phase motor applications up to 7.5kW@400V. It provides full protection to motors with a rated current Ir 4.5-18A (Ir adjustable), overload tripping class 20, short circuit at 13 x Irmax, overcurrent at 14.2 x Ir, phase loss, insulation fault (protection of equipment only). For diagnostics, it provides a thermal overload alarm to be managed with an additional function module (to be ordered separately) and a test push button for overload simulation. To be used with a 110-240V AC / 110-220V DC 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), Green Premium compliant (RoHS/REACh).
