Sensata | Crydom Solid-State Relay, 50A Current Rating, Screw Terminals - Series 1 Series - A2450


Use this solid-state relay from Sensata | Crydom to turn power on and off in your electric circuits. As it has no physical contacts, this unit transmits the electrical signals in an optical form. This helps to minimise the risk of wear, giving you an extended service life. For durability, anti-rotation barriers in the housing help prevent misalignment in the event of heavy vibrations. Thanks to its maximum turn-on time of 20ms and turn-off time of 30ms, you can use this SSR with devices that need rapid power switching. It's commonly used in lighting and heating applications.

• Broad operating temperature range between -40°C and +80°C to withstand use in harsh environments
• Compact dimensions of 57.3 (H) x 23.3 (W) x 44.5mm (D) to maximise space in your setup
• Durable aluminium baseplate resists impact and corrosion
• Load voltage range between 24 and 280V AC for use in low-voltage systems

What's the current rating of this SSR?


This SSR has a current rating of 50A for use in heavy-duty applications.
