To prevent hazardous situation in case of catastrophic contact failures like contact welding, please carefully evaluate the relay application parameters, to assure a fail-safe design. This is particularly important in case of over spec use and long periods of continuous use. 2. Use of a varistor in parallel over the coil is recommended to clamp reverse inductive voltage surges. Reverse blocking voltage should be about 3 times the surge voltage level. 3. A contact carrying currents higher than 10A, it is recommended to consider addition heat develop in the PCB contact tracks. 4. Specified values are valid in case of series connection of coils, by connecting pin 2 and 3, at Tamb 20C and at zero contact current. 2
