Frequently Asked Questions
- What’s the difference between the RIB013P and RIBU1C? The RIB013P is a 3PST relay rated for 20A with a 120 VAC coil. The RIBU1C is a universal-voltage SPDT relay designed for more general-purpose switching.
- Can the RIB013P handle motor or ballast loads? Yes, it is rated for up to 7.5 HP at 480 VAC (3-phase) and 20A ballast loads up to 480 VAC. It is not rated for electronic ballasts.
- Is this relay suitable for plenum installations? Yes, the RIB013P is UL-listed and approved for use in plenum spaces with a NEMA 1 enclosure.
Installation Tips & Mistakes to Avoid
- Tip: Always confirm your control voltage matches the coil. The RIB013P requires 120 VAC to activate the relay.
- Tip: Use proper strain relief when mounting the conduit nipple into a panel or junction box.
- Mistake to Avoid: Do not use this model with LED drivers or electronic ballasts — choose a model rated for that type of load.
- Mistake to Avoid: Avoid mounting outdoors or in unsealed areas. This relay is NEMA 1 rated for dry, indoor locations only.
Common Applications
1. HVAC Equipment Control
The RIB013P is an excellent choice for switching high-power loads such as air handling units, compressors, exhaust fans, and electric heaters. Its 3PST contact arrangement is ideal for breaking three separate circuits simultaneously, making it effective for systems where multi-phase equipment is common.
2. Lighting Control in Commercial Spaces
With a 20A ballast rating up to 480 VAC, the RIB013P is commonly used in lighting panels for warehouses, gymnasiums, and parking structures. It is not, however, rated for electronic ballasts or LED drivers — for those loads, a relay rated for electronic ballasts should be used instead.
