WATTSTOPPER HDR-9 LOW VOLTAGE LIGHTING CONTROL RELAY, 1-POLE, 120/277/347V, 20A

I appreciate black housing for its understated style, which keeps the focus on the wiring and layout.

If you prefer a low profile look, the black color should make it easy to integrate without clashing.

You will find that the PLC-RSC-24UC/21 behaves predictably during long runs, which brings peace of mind.
