Earth-fault release 30mA, AC/DC sensitive, 4p
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: AC/DC current sensitivity according to the core-balance principle (in range 0 … 100 kHz). Observe response threshold dependence on frequency! See “Frequency response” characteristic curve. Adjusting buttons can be sealed. Can be used for NZM2-4, N2-4

Description	Core-balance principle with AC/DC sensitivity (in range 0 - 100 kHz) For 4 pole NZM2-4 circuit-breakers and N2-4 switch-disconnectors Internal power supply Us = 50 - 400 V
Contact sequence
Contact sequence
For use with	NZM2-4 N2-4
Pole	4 pole
Notes	Observe response threshold dependence on frequency! See “Frequency response” characteristic curve Auxiliary contacts (1 N/O, 1N/C integrated) are reset via the reset button. Not in combination with plug-in units, insulated enclosure or main switch assembly kit for side panel mounting with mounting bracket. Rated ultimate short-circuit breaking capacity is determined by the fitted NZM2. If a switch-disconnector N2 is applied by the back-up fuse to be used ￫ Technical data.
