Chint NDK-250VA Circuit CT 250VA

The NDK-250VA is a Chint open-frame control circuit transformer designed to provide safe and stable voltage transformation for industrial and building control applications. It steps down or steps up mains voltage to lower control voltages suitable for relays, contactors, timers, indicators, and other control devices used in electrical panels. It is commonly used in distribution boards and automation systems where reliable isolated control power is required.
