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, one from 800 A to 3000 A and the other for 4000 A to 5000 A.
The Masterpact NW enables standardisation of electrical switchboards by providing unrivalled simplicity in terms of both choice and installation.
