The Eaton NZM2/3-XU24DC is an Alarm Contact (or Trip Indicator Contact) accessory module designed for the NZM2 and NZM3 frame sizes of Eaton's NZM series molded case circuit breakers (MCCBs).
This device is a special type of auxiliary contact that provides a remote electrical signal specifically and only when the breaker has tripped automatically due to an overload or a short-circuit fault. It is mechanically designed to differentiate between a manually switched OFF breaker and one that has tripped on a fault.
