Discovering Masterpact
The Masterpact NW range of circuit breakers and switch-disconnectors offer current ratings from 800 A to 6300 A. Five different performance levels are available: b N1: standard with total discrimination b H1: high performance with total discrimination b H2: a compromise between current limiting and discrimination b H3: high breaking capacity and discrimination, without current limiting b L1: high level of current limiting, with some discrimination.
