TeSys Giga Circuit-breakers
TeSys Giga Circuit-breakers
Product Description
Circuit-breakers, coordinated with TeSys D and TeSys F contactors, to protect motors up to 500 A (250 kW / 400 V).
Part of TeSys.
*TeSys GV5 & GV6 range of motor circuit breakers are designed for protecting motors from over-load, short circuit faults, phase unbalance or phase-loss.
Features
- 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
Benefits
- The universal fixing arrangement makes installation simple: Screw fixing.
- Incorporated an ingenious combination of advanced electronics and electromechanical technology that provides more effective protection and is ideal for demanding applications.
