Function and Usage
The NXC-XMG series AC contactors are mainly used for AC 50Hz (or 60Hz), rated working voltage up to 690V, frequently connecting and disconnecting circuits under AC-1 and AC-3 usage categories at 400 (380V) AC. They can be combined with appropriate thermal overload relays to form electromagnetic starters. The product has an IP50 dust protection rating (excluding terminal wiring), and the normally closed auxiliary contacts are of weak signal conduction type; customized normally open auxiliary contacts of weak signal conduction type or both normally open and normally closed auxiliary contacts of weak signal conduction type are available, suitable for scenarios with sensitive conduction requirements for auxiliary contacts.
