Capacitor unit 230 V 50/60 Hz
in conjunction with shunt release
NZM...-XA208-250 AC/DC
Enclosure: degree of protection IP20
Not UL/CSA approved
Enables the reliable use of circuit-breakers as mesh network
circuit-breakers in the range from 0 – 110 % U
n
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 capacitor unit is arranged independently of the circuit-breaker.
Connect NZM‐XCM to the power feed side.
Note on engineering:
Connect a standard auxiliary contact (HIN) as N/O in series with the
coil of the shunt release!
Standard auxiliary contact not included as standard.
