Electromechanical Relays for Hazardous Locations

[whycliffrussell]

I am looking for a single pole double throw electromechanical relay for:

Class 1, Zone 1, Gas Group IIC OR IIB+H2, Temp Code at least T3.

It needs a 120V coil.
Contacts rated at at least 120V and 8A.

I fairly certain you will need to use an explosion-proof enclosure to house the relay.

Another way is to house the relays outside of the Class 1, Zone 1 area! That way, you could use common relays and do away with explosion-proof enclosures!
