Residual current release, 300mA, 4-pole, down 104614

Optional accessories for the NZM range of circuit breakers include a wide range of devices suitable for international use. Installation is flexible and easy thanks to modular functional groups.

Notes: Complies with IEC/EN 60947-2 without UL/CSA approval. Can be used in three- and single-phase installations. Sensitivity to impulse current according to the principle of summation currents. For 3- and 4-pole NZM1(-4) ACBs and N1(-4) load breakers. Dependent on mains voltage Ue = 200 .. 415 V 50/60 Hz. At I △n = 0.03 A: Delay time t v always set to 10ms. Warning message > 30 % I △n via yellow LED. Trip message via up to 2 attachable auxiliary switches (HIAFI): S = M22-K01, ZR = M22-K10 is reset using the reset rocker. When using tripping auxiliary switches in the FI block, the NC contact works as a NO contact and the NO contact as an NC contact. Double contact is not allowed. Cannot be combined with an insulating housing or a main switch mounting kit for mounting on a side wall with a mounting bracket. NZM1-XFI..R not to be used in combination with NZM1-XUSA bottom cover. NZM1-XFI..U Cannot be combined with insulating housing or main switch mounting kit for side mounting with mounting bracket. The rated ultimate short-circuit breaking capacity is defined by NZM1, NS1. In the case of the N1 switch-disconnector, by the applied pre-protection. See technical data. Applicable to: NZM1-4, N1-4
