Schneider Electric motor-protective circuit-breaker GV6P320H: further details
TeSys GV motor-protective circuit-breaker, 3 poles (3P), 320A/690V, for the protection of 3-phase motors 132-160kW at 400V. It offers thermal magnetic protection and additional protective functions, breaking capacity Icu 70kA, start-stop control by rotary handle. It also offers connection for bars or cables with cable lugs (direct connection of cables with additional plugs). Thermal protection adjustable by dials with a setting current Ir in the range 160-320A and a selectable tripping class 5, 10 or 20, magnetic protection at 15 In. Additional fixed-tap protection functions are short-time delay protection Isd at 13 Ir, phase unbalance and failure protection. It provides internal locations for additional auxiliary contact blocks (OF, SD) and voltage releases (MN, MX). Certified to several standards (IEC, UL, CSA, CCC, EAC, Marine), Green Premium compliant (RoHS/REACh).
