Notes:

1.

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.
