TeSys Giga circuit breakers are specifically designed for demanding motor control and protection applications.
● 4 current ratings: 150A, 220A, 320A & 500A
● 2 breaking capacities (Icu): 36kA & 70kA @ 400/415V AC
● Ics = 100% Icu
● Equipped with advanced Micrologic trip unit which provides over-load and short circuit protection along with phase-unbalance or phase-loss protections
● Adjustable overload protection (Ir): 50..100% x In, includes trip class selection (Class 5, 10, or 20)
● Adjustable Short-time protection threshold (Isd): 5…13 x In with fixed time delay
● Short-Circuit instantaneous protection (Ii): 15 x In (max rating of the trip unit)
● Front LED indications: Green LED for pre-alarm before the event of a fault and Red LED for motor operation
● Suitable for isolation, as per IEC standards
● Control by the direct rotary handle as standard, by the door-mounted extended rotary handle as an option
● Wide range of auxiliaries for control and additional protection
● Connections: busbars/ cables with lugs
● Compliance with standards: EN/IEC 60947-1; IEC 60947-2; IEC 60947-4-1; UL 60947-4-1; CSA C22.2 No 60947-4-1
● Optional Thermal Fault module (SDTAM) to indicate over-load and to open contactor (before breaker tripping) in event of overload or phase unbalance
