SCHNEIDER SDDR-DZ7 Shutdown Auto Restart Relay

The Schneider Electric SDDR-DZ7 Shutdown Auto Restart Relay is an industrial protection and control relay designed to monitor power conditions and automatically restart equipment after temporary power interruptions or voltage drops. It is commonly used in motor control systems to prevent downtime caused by short “voltage dips” (brownouts) and to ensure smooth automatic recovery of industrial machines after shutdown conditions.

This device is widely applied in factories where continuous operation is critical, such as production lines, pumps, conveyors, compressors, and automated machinery systems.
