Frequently Asked Questions

What is the ATC DIVERSIFIED ELECTRONICS SUA440ASA phase monitor relay used for?

The SUA440ASA phase monitor relay protects three-phase industrial equipment by detecting phase loss. When a phase is lost, the relay triggers a response to shut down or alarm connected machinery, preventing damage to motors, compressors, and pumps in manufacturing, HVAC, and process control applications.

What are the specifications of the ATC DIVERSIFIED ELECTRONICS SUA440ASA?

The SUA440ASA is a socket-mounted relay from the SUA Series. It monitors for phase loss with an input voltage of 430 to 480V AC. The manufacturer part number is SUA440ASA, and it is designed for protecting three-phase equipment from phase-loss conditions.

Where to buy the ATC DIVERSIFIED ELECTRONICS SUA440ASA worldwide?

3G Electric supplies the ATC DIVERSIFIED ELECTRONICS SUA440ASA phase monitor relay worldwide. As a global industrial distributor, we handle full logistics, customs clearance, and delivery to your site. Contact us for availability and lead time on this socket-mounted relay.

How to install the ATC DIVERSIFIED ELECTRONICS SUA440ASA phase monitor relay?

Install the SUA440ASA by mounting it into a compatible socket and wiring the three-phase input voltage (430 to 480V AC) per the wiring diagram. Ensure power is off during installation. Follow standard relay socket-mounting best practices and verify phase rotation before energizing the monitored equipment.
