LUCA18FU
Details
TeSys U standard control unit to be inserted in power bases LUB32, LUB32, LUB38 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 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 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).
