Functional Devices RIB043P Enclosed Relay 20A 3PST 480VAC

Dependable high-voltage switching for security, surveillance and industrial monitoring systems. The Functional Devices RIB043P enclosed relay is engineered to provide reliable control for access control panels, HVAC, machine control and remote monitoring applications. With a 20A switching capacity and a 3PST-N/O contact arrangement, the RIB043P lets technicians safely isolate multiple circuits or phases while maintaining consistent performance.

This relay features a 480 VAC coil for direct compatibility with common commercial power systems and an enclosed housing that reduces dust and moisture exposure — extending service life in demanding environments. Its compact 4" x 2" footprint eases panel layout and retrofit work, while RoHS and WEEE compliance and U.S. manufacturing ensure responsible sourcing and regulatory alignment.

Choose the Functional Devices enclosed relay when you need robust, space-saving switching that integrates cleanly into security, surveillance, monitoring and industrial control systems. Order the RIB043P to upgrade reliability and simplify installation in your next project.

• Dependable high-current switching: delivers up to 20A capacity to protect and control critical circuits without overheating or nuisance trips.
• Three-pole isolation for cleaner system design: 3PST-N/O contacts let you switch multiple phases or separate loads in security and industrial panels.
• Enclosed, rugged construction: sealed housing reduces dust and moisture ingress for longer life in monitoring, surveillance, and outdoor equipment.
• High-voltage compatibility: 480 VAC coil support simplifies integration into commercial power and HVAC control systems.
• Compact, panel-friendly footprint: 4" x 2" size saves space in enclosures and simplifies retrofits and new installations.
