Do you have any General-purpose Relays with a rated coil voltage of 380 or 400 VAC?
Answer
Relays can be used for a rated coil voltage of up to 200 VAC, and Contactors can be used for up to 400 VAC. There are no Relays with a rated coil voltage of over 240 VAC. To operate at 400 VAC, use a transformer to reduce the voltage or use Contactors.
