Motor circuit breaker, TeSys GV4, 3P, 50A, Icu 25kA, thermal magnetic, Everlink terminals
Description
TeSys GV motor circuit breaker, 3 poles (3P), 50A/690V, for protection of 3-phase motors 11-22kW@400V. It provides thermal magnetic protection and additional motor protection functions, breaking capacity Icu 25kA@400V, start-stop control by toggle, connection by Everlink BTR screw terminals. Thermal protection adjustable by dials with a setting current Ir in range 20-50A and a selectable tripping class 10 or 20, magnetic protection at 17 In. Additional protections have fixed pick-up and include short time delay protection Isd at 13 Ir, phase unbalance and loss protection, ground fault protection. It makes internal locations available for additional auxiliary contact blocks (OF, SD), and voltage trip units (MN, MX). Multi standards certified (IEC, UL, CSA, CCC, EAC, Marine, ATEX), Green Premium compliant (RoHS/REACh).
