Special features

Capacitor unit 230 V 50/60 Hz in conjunction with NZM...-XA208-250 AC/DC shunt release

Enclosure: degree of protection IP20

not UL/CSA approved

Enables the safe use of circuit-breakers as mesh network circuit-breakers in the range from 0 – 110 % Un with constant switch-off time of 40 ms.

If the mains voltage is absent, the installed capacitor supplies power for actuating the shunt release for at least 12 hours.

The configuration of the capacitor unit is undertaken independently of the circuit-breaker.

Connect capacitor unit to the supply side!

Engineering Guidelines: Connect a standard auxiliary contact as N/O in series with the shunt release!

Standard auxiliary contact not included as standard.
