Schneider Electric RUMC22B7 Octal Plug-in Relay Dpdt 24 Vac

Product Description

The SCHNEIDER ELECTRIC RUMC22B7 is an octal plug-in electromechanical general purpose relay designed for control panel and automation applications. Rated for 10 amps at 277 VAC and 30 VDC, this DPDT relay operates on a 24 VAC coil voltage, making it a standard fit for low-voltage control circuits in HVAC, building automation, and industrial control systems. The octal base configuration allows for quick insertion into a compatible octal relay socket, simplifying replacement and field servicing. Licensed electricians and controls technicians are the primary installers. The compact body measures 1.37 inches wide, 2.2 inches high, and 1.39 inches deep, fitting standard DIN-rail-mounted socket bases.

This relay is suited for residential and light commercial HVAC control panels, building management systems, and general-purpose industrial control applications where a DPDT switching configuration is required. The 24 VAC coil voltage aligns with common low-voltage thermostat and control circuit standards. It handles switching loads across a wide voltage range, making it versatile for mixed AC and DC control circuits. Controls technicians and licensed electricians commonly specify this relay for fan coil units, air handling units, and packaged rooftop equipment control panels.

Key Features

• DPDT contact form supports two independent switched circuits from a single coil
• 10 amp contact rating at 277 VAC handles standard control circuit loads
• 24 VAC coil voltage matches common low-voltage HVAC and BAS control circuits
• Octal plug-in base allows tool-free relay body replacement without rewiring the socket
• 3 VA power rating at 60 Hz reflects low coil power draw suitable for transformer-fed circuits
• Meets CSA, UL 508, UL Recognized, RoHS, REACH, and EN/IEC 61810-1 standards

Compatibility

Designed as a plug-in replacement for octal-base DPDT relay sockets in residential and commercial HVAC control panels and general-purpose industrial control applications. Requires a compatible octal relay socket base; socket sold separately.

Installation Notes

Installation should be performed by a licensed electrician or qualified controls technician in accordance with NEC requirements. De-energize and lock out the control panel before removing or inserting the relay body. Confirm the socket base is rated for the intended load voltage and current before inserting the relay. Do not exceed the rated contact current or coil voltage to avoid premature contact wear or coil failure.
