Special features

Delay unit for combination with special undervoltage releases.

For use with emergency-stop devices in connection with an emergency-stop button.

not UL/CSA approved

Voltage dips of less than the setting between 0.06 – 16 s do not cause disconnection of the NZM circuit-breaker or N switch-disconnector.

Delay time can be set from: 70 ms – 4 s.

With additional external capacitor: 30,000 µF ≧ 35 V to 8 s, 90,000 µF ≧ 35 V to 16 s.

A special release is required.

Cannot be installed simultaneously with separate NZM...-XHIV early-make auxiliary contact or NZM...-XA... shunt release.

Delay unit for separate installation. Fixing: top-hat rail or screws.

For other operating voltages use a control transformer.
