Masterpact NW Air Circuit Breakers

The market leading Air Circuit Breaker, for high performance applications:

Rated performance: 800-6300A, Icu=ics=42-150kA at 220/415Vac
Voltage rating: up to 1000 V
Only 2 frame sizes and 2 pole pitches (800-4000A and 4000-6300 A), to simplify mechanical assembly in switchboard
3- and 4-pole versions
5 types of Micrologic control units with added measurement, energy-management and network-analysis functions
Earth leakage protection built into the control unit
Wide range of common auxiliaries and accessories interchangeable on site
Compliance with international standards IEC 60947-1 and 2, IEC 68230 for type 2 tropicalization, UL489 and ANSI/UL1066, as well as CCC and GOST certifications
Compliance with specifications of marine classification bodies: Bureau Veritas, Lloyd’s Register of Shipping, Det Norske Veritas, etc.

Benefits

The worldwide benchmark for high-current circuit-breakers, known everywhere
The Masterpact NW circuit-breaker range features optimised dimensions: not only is it more compact, but even better two sizes are sufficient to cover requirements from 4000 to 6300 A.
At a time when installations are becoming increasingly complex, Masterpact NW enables standardisation of electrical switchboards by providing unrivalled simplicity in terms of both choice and installation.

Applications

Protection, measurement and communication of LV electrical networks
Generator protection
Motor protection
DC networks
Protection of installations in highly corrosive industrial environments
Mines (special 1000V version of NW)
Navy
Earthing switch
High short-circuit current limiting (ultra-rapid Masterpact UR)
