General Carlo Gavazzi process control

Carlo Gavazzi 2 and 3 pole relays offer mercury-free switching solutions.

Carlo Gavazzi introduced its RMD Hybrid Relays that are mercury-free and designed for controlling the heating element inside of food ovens, warmers, fryers, rotisseries and other food equipment. They are one of the few products of their type available on the market which is capable of switching up to 20 cycles per minute, with a 4 million electrical cycle life expectancy.

The RMD Series combines solid state and electromechanical technology to eliminate contact arcing and provide full amperage rating up to 60°C. The RMD3H switches heaters on three legs while the lower cost RMD2H switches two poles and the third pole is directly connected between L2 and T2. The relays are rated for 4 million electrical cycles and 20 cycles per minute with three common control voltages: 24VAC, 120VAC, 240VAC.
