If used in combination with the SASY 60i busbar system, Eaton's NZM series of circuit breakers covers rated currents from 20 to 630 A – with only three frame sizes. They are also optimally matched to each other and meet the demands of a wide range of applications. We took a close look at what customers really want and designed the product accordingly. What stands out, for example, is the comprehensive portfolio of accessories, which can be individually assembled and easily installed in line with specific application requirements. The same goes for the innovative SASY 60i adapters up to 630 A, which offer increased safety for operators. The NZM circuit breakers up to 630 A are tested and verified in combination with the SASY 60i MCCB adapters with a short-circuit breaking capacity of up to 50 kA.
