Sensata | Crydom Solid-State Relay, Zero-Cross Switching Type, 48 to 530V AC Load Voltage Range - CKR Series - CKRD4820

Keen to switch your your equipment on and off in a snap? Choose this Sensata | Crydom solid-state relay. By opening and closing your circuit in response to electrical signals, it makes light work of standard control tasks. Wear is no problem for this device, as it has no moving parts. A handy LED indicator glows when the unit is receiving power, making status monitoring a breeze. As its box clamp terminals hold your wires securely in place, the component stops vibrations from pulling the plug on your process. You'll find relays like this used in plastic processing systems and automotive manufacturing.

• Compact dimensions of 81.9 (H) x 22.5 (W) x 99mm (D) for installation in tight spaces
• Broad load voltage range between 48 and 530V AC for versatility
• Quick turn-on and turn-off time of half a cycle for lightning-fast switching
• Thermally conductive epoxy encapsulation helps the unit keep its cool

How do I mount this SSR?

This device simply snaps onto a standard DIN rail, making for quick and tool-free installation.
