Eaton εκλυτήρας υποτάσης NZM2/3-XU24DC 24V DC (259509)

In industrial power distribution, a voltage dip can cause motors to stall, contactors to chatter, or processes to drop out unexpectedly. The Eaton NZM2/3-XU24DC undervoltage release solves this by automatically tripping the connected NZM2 or NZM3 circuit breaker when the control voltage falls below a safe threshold. This protects downstream equipment from undervoltage conditions and enables safe re-energization sequences.

Who is it for

Electrical engineers, panel builders, and maintenance teams working with Eaton NZM2 or NZM3 moulded case circuit breakers in industrial control panels, machine tools, or building infrastructure. It is particularly useful where automatic load shedding or safety interlocks are required on voltage loss.

Main features

Tips

Always verify that the control voltage matches the supply voltage of your application. For safety circuits, combine with a shunt release or auxiliary contact to signal the tripped state to a PLC or monitoring system.
