Optional accessories for the NZM circuit breaker series offer an extensive portfolio of application options for worldwide use. Installation is flexible and simple thanks to modular function groups. Notes: Capacitor device 230V 50/60 Hz in conjunction with shunt release NZM..-XA208-250AC/DC. Housing: Protection class IP20. Not UL/CSA approved. Enables the safe use of the circuit breaker as a mesh network switch in the range 0-110% Un with a constant switch-off time of 40ms. If there is no mains voltage, the built-in capacitor supplies the energy required to operate the shunt release for at least 12 hours. The capacitor device is arranged independently of the switch. Connect the capacitor device on the feed side. Project planning note: Connect the standard auxiliary switch (HIN) as a normally open contact in series with the coil of the shunt release! Standard auxiliary switch not included in delivery. Can be used for: NZM1(-4), N(S)1(-4), NZM2(-4), N(S)2(-4), NZM3(-4), N(S)3(-4), NZM4(-4), N(S)4(-4)
