The Eaton Industries MCCB circuit-breaker series NZM offers a range of optional accessories that are suitable for global usage due to its international approval standards, excluding UL/CSA. These accessories allow for flexible and easy mounting due to their modular functions, and they are designed for use in both three- and single-phase systems. The system operates according to the core-balance principle and it can be used for 3 and 4 pole NZM1(-4) circuit-breakers and switch-disconnectors N1(-4). The circuit breaker operates independently of mains voltage, ranging from 200 to 415 V, 50/60 Hz. It has an adjustable delay time, a warning system to indicate fault levels via a yellow LED, and the option to fit up to two auxiliary contacts. It does not support units with double contact, insulated enclosure, and a few other components as specified in the original description. Its short-circuit breaking capacity is defined by the fitted NZM1, NS1. The back-up fuse will define it when using a switch-disconnector N1.
