Greeting to all, Our company makes Laboratory Instrumentation which many employs a small furnace. In case the furnace control circuit fails, we have a secondary Over Temperature Protection Circuit (OTPC) which opens a double pole relay to shut power off to the heater coils.
In a new design we are working on, the Relay in the OTPC only has an Open Contact dielectric strength rating of 1000VAC. Basic insulation according to EN61010-1 would be 1350VAC or 1900VDC. The relay does meet Reinforced insulation requirements between the contacts (primary mains 230VAC) and the Secondary Coil. Does this relay have to have an Open Contact dielectric rating that meets Basic Insulation requirements to be used in a OTPC circuit?
