I like that the DEC DU1PU 246A 250VAC model keeps things simple for wiring and setup.
1Pce PA66-GF33 Automotive Relay for Car 4Pins DC12V 35A
With a 48V model, you get a relay that feels steady, even when loads shift during normal operation.
You will find that wiring the Clipsal L5512RVF is straightforward even on a busy board.
With the black color, the relay blends in well, which can make the whole panel look more cohesive.
