Shunt release, for capacitor unit
Optional accessories for the circuit-breaker series NZM offers a comprehensive portfolio of application options for use world wide. The mounting is always flexible and easy thanks to the modular function groups. Notes: 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 40ms. 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 (HIN) as N/O in series with the shunt release! Standard auxiliary contact not included as standard. Can be used for: NZM1(-4), N(N/O)1(-4), NZM2(-4), N(N/O)2(-4), NZM3(-4), N(N/O)3(-4), NZM4(-4), N(N/O)4(-4)
