RIB Relays RIB2421B Enclosed Power Control Relay

RIB2421B Enclosed Power Control Relay delivers reliable power control for industrial circuits. This AC/DC operated unit uses a compact NEMA 1 enclosure with SPDT contacts, making it ideal for pilot duty, ballast loads, and other demanding control tasks.

With flexible coil options, the relay supports 24/208 to 277/120 VAC at 50/60 Hz, plus 24 VDC, enabling seamless integration with your control system. Contact ratings cover 5/20 A resistive, 16/20 A ballast, and 10 A tungsten across voltages up to 277/480 VAC (resistive) or 120/277 VAC (pilot and ballast).

UL 916/864, CUL, UL (Canada and US), and CE approvals, plus RoHS compliance, ensure safety and compatibility. The unit measures 3.2 x 1.8 x 2.3 inches and includes a built-in LED, 16-inch 600V-rated wiring, and a 0.5-inch threaded nipple for quick installation.
