Carlo Gavazzi offers a comprehensive range of solid state relays (SSR’s) featuring direct copper bonding technology for increased life and reliability. SSR’s are used extensively in the plastics, packaging, food processing, and HVAC industries - primarily for temperature control. They are the logical replacement for mercury contactors.

Other applications include lighting and pump switching. Furthermore, many of our solid state relays feature horsepower ratings making them suitable for controlling motorized dampers in HVAC control systems - where their long life and noise-free switching make them ideal replacements for mechanical contactors.

Carlo Gavazzi's solid state relays range includes single phase relays up to 125 amps and 3 phase relays up to 75 amps. They are available with both digital and analogue inputs (4-20 mA or 0-10 V) Furthermore, we also offer a complete range of SSR's with a built-in heatsink.
