• How is the RIB023P different from the RIB013P?
  The main difference is the coil voltage. The RIB023P operates on 208–277 VAC, whereas the RIB013P uses 120 VAC. This makes the RIB023P ideal for high-voltage panels in commercial settings.
• Can the RIB023P be used with inductive loads?
  Yes. The relay is rated to handle inductive loads, including motors up to 7.5 HP (3-phase @ 480V) and ballast lighting (excluding electronic ballasts).
• Is this relay approved for use in plenum spaces?
  Yes, it is UL-listed and approved for plenum-rated applications. It features a NEMA 1 housing and meets multiple industrial safety standards.

• Tip: Confirm that your control signal is within the 208–277 VAC range before selecting this model. Lower voltages will not activate the relay.
• Tip: Suitable for commercial lighting, HVAC, and automation panels with high-voltage supply lines.
• Mistake to Avoid: Do not attempt to power this relay with 120 VAC — it won’t engage and may lead to troubleshooting delays.
• Mistake to Avoid: This model is not rated for outdoor or wet locations. It is NEMA 1 rated for dry, indoor use only.

"We spec the RIB023P for all our 277V lighting control panels. Reliable and easy to wire, especially with factory-mounted enclosures."
