SUA-440-ASA | Elevator Phase Monitor Relay – Fixed 440 VAC, Phase Loss & Reversal Protection

SUA-440-ASA | Elevator Phase Monitor Relay

The SUA-440-ASA Phase Monitor Relay protects 3-phase elevator traction and control circuits against phase loss, under-voltage, and phase reversal on fixed 440 VAC lines (430–480 VAC range).

Featuring a robust SPDT electromechanical relay output and a compact polycarbonate housing, the SUA-440-ASA mounts easily on an octal 8-pin socket. UL-recognized for U.S. and Canada use, it operates from 32 °F to 131 °F and is RoHS compliant for safe, long-term service.

• Monitors phase loss, under-voltage, and phase reversal on 440 VAC 3-phase lines
• Fixed 440 VAC operation (430–480 VAC range)
• SPDT relay output rated 10 A @ 240 VAC resistive
• Compact polycarbonate housing; mounts on octal 8-pin socket
• Operating temperature: 32 °F to 131 °F (0 °C to 55 °C)
