Schneider Electric 8501X040 Timing Relay

Schneider Electric's Square D 8501X040 Timing Relay is a Type X NEMA‑style timing relay designed for robust AC control in industrial panels. Built for 110–120 V AC coil operation, it integrates with the 8501 family to provide timed control within standard control circuits. Use cases include sequencing and interlocking tasks such as motor‑start sequences, conveyor timing, and other automation steps where a precise delay is needed between input signals and a switched output. The device shares the rugged, modular philosophy of Square D relays, enabling straightforward installation and compatibility with other 8501‑series components in the same control scheme. When selecting a timing relay, verify the coil voltage matches the control power (110–120 VAC) and confirm it fits the enclosure and wiring practices used for Square D/NEMA relays in your panel.
