Notes
1) For NA switch switching capacity with NZM…1-…(C)NA the following applies: 480 Y/277 V from 60 A
2) For AC-3 rated operational current with NZM4 the following applies: 400 V: max. 650 kW; 690 V: max. 600 kW
3) For NA switch switching capacity with NZML2 and NZML3 the following applies: Current Limiting switch to UL489
4) For 3-pole system protection circuit-breaker the AC-3 specification is not applicable
5) For NA switch switching capacity with NZML4 at 240 V 60 Hz the following applies: on request
6) For current heat loss per pole the specification refers to the maximum nominal current of the frame size.
7) For 3-pole system protection circuit-breaker the following applies: 400/415 V 7500 switching operations
8) Maximum back-up fuse, if the expected short-circuit currents at the installation location exceed the switching capacity of the circuit-breaker.
9) F 1600 A
10) Higher switching capacity on request
