MOTOR CIRCUIT-BREAKER TESYS 70-150A 55-75kW 400V 70KA

Reliable and robust motor protection circuit breakers up to 500A/250kW/400V with a wide-range protective relay. TeSys GV5 and GV6 motor protection circuit breakers are designed to protect motors against overload, short-circuit, phase imbalance, and phase loss. The breakers are specifically designed for demanding motor control and protection applications. ? 4 rated currents: 150A, 220A, 320A & 500A ? 2 short-circuit withstand ratings (Icu): 36kA & 70kA @ 400/415V AC ? Ics = 100% Icu ? Equipped with a Micrologic protective relay designed to protect the motor against overload and short-circuit conditions and to act as phase imbalance and phase loss protection. ? Adjustable overload protection setting range (Ir): 50...100% x In and starting time class setting (Class 5, 10 or 20) ? Adjustable short-circuit trip setting range (Isd): 5...13 x In with fixed time delay ? Instantaneous short-circuit trip (Ii): 15 x In (maximum relay current) ? Relay LED indication. Green LED: operational status (ready to trip). Red LED: predictive alarm signal, motor thermal state >95% of rated value ? Manual operation as standard ? Handle operation as optional accessory ? Wide range of electrical accessories and mechanical fittings ? Cable lug/bar connection as standard. Tunnel connectors optional. ? Standards: EN/IEC 60947-1; IEC 60947-2; IEC 60947-4-1; UL 60947-4-1; CSA C22.2 No 60947-4-1 ? Optional fault discrimination module (SDTAM) enabling detection of overload and triggering contactor opening (before tripping) in overload and phase imbalance conditions ? Type 1 and Type 2 short-circuit coordination for two-component motor starter solutions together with TeSys contactors This product description is an automated translation of the original Finnish description.
