That's the coolant output's spec docs:blackbox-x32:connect-coolant [OpenBuilds Documentation] Relay is something else. Max 6A (for BlackBox 4X per title of thread) , dry contact but keep to DC please
Not really rated, but documented for specific use cases. X32 is <3A (smaller than 4X to fit extra relay) Ps OP was asking about the 4Xs relay, the above is an X32 - different specs - see thread title
