Square D 8501RSD43V53 General Purpose Relay 3PDT 24 Vdc

Product Description

The SQUARE D 8501RSD43V53 is an electromechanical plug-in general purpose relay designed for control circuit switching in a wide range of industrial and commercial applications. It features a 3PDT (triple-pole double-throw) contact configuration rated at 10 amps at 250 VAC, with a 24 VDC coil voltage. The plug-in terminal type allows for fast, tool-free installation into a compatible relay socket base. This relay suits licensed electricians and control panel technicians working on automation, HVAC controls, lighting circuits, and similar low-voltage switching applications.

This relay is suited for use in residential, commercial, and light industrial control panels where reliable electromechanical switching is required. Typical install scenarios include HVAC unit controllers, building automation panels, motor starter auxiliary circuits, and general-purpose switching logic. Its compact footprint and plug-in design make it practical for retrofit and new-installation work in DIN-rail or panel-mount socket assemblies.

Key Features

• 3PDT contact configuration for flexible switching in multi-circuit control applications
• 10-amp contact rating at 250 VAC supports a broad range of control loads
• 24 VDC coil voltage compatible with common low-voltage control circuits
• Plug-in terminal type enables fast replacement without rewiring the socket
• CE, CSA, UL Recognized, and RoHS Compliant for use in code-required installations

Compatibility

Designed as an OEM-style plug-in general purpose relay for use with compatible relay socket bases accepting 3PDT plug-in relay footprints in control panel and automation applications.

Installation Notes

Installation should be performed by a licensed electrician following applicable NEC guidelines. De-energize and lock out the control panel before removing or inserting the relay into its socket base. Verify coil voltage and contact rating match the circuit requirements before energizing. Do not exceed the rated contact current or voltage under any operating condition.
