Sensata | Crydom Solid-State Relay, Zero-Cross Switching, SCR Output - H12WD Series - H12WD4850PG

Turn your system off and on with this solid-state relay from Sensata | Crydom. This component features overvoltage protection to prevent sudden surges from damaging your circuits. The DBC substrate offers superior thermal performance thanks to the ceramic base, which dissipates heat to keep the device working efficiently. Its LED status indicator makes it easy to monitor and troubleshoot. You'll find it used in lighting and heating applications.

• Broad operating temperature range between -40°C and +80°C for use in demanding environments
• Compact dimensions of 44.5 (L) x 22.6 (W) x 57.3mm (H) for installation in tight spaces

How do I install this SSR?

You can easily install this SSR on a panel using the included SEMS screws and washers. The anti-rotation housing barriers will prevent vibrations or impact from loosening the screws for secure installation.

What accessories work with this device?

You can add a protective cover (789-8475) to prevent electric shock during handling. This SSR also accommodates a heat sink (703-4558) and a thermal pad (743-4860) to keep your system from overheating for efficient performance.
