Square D 8501RSD41P14V53 General Purpose Relay Spdt

Product Description

The SQUARE D 8501RSD41P14V53 is an electromechanical plug-in general purpose relay rated for 12 amps at 240 VAC with a 24 VDC coil voltage and a single-pole double-throw (SPDT) contact form. This relay is designed for control circuit switching in HVAC, industrial, and commercial electrical systems. The plug-in form factor allows fast field replacement without rewiring the socket base. It carries CE, CSA, and UL Recognized listings and is RoHS compliant, making it suitable for installations where certification compliance is required. Electricians and HVAC controls technicians are the primary installers of this relay type.

This relay is commonly used in low-voltage control circuits across residential and light commercial HVAC equipment, as well as general-purpose industrial control panels. Typical applications include switching loads such as fans, contactors, pilot lights, and small motor circuits. The plug-in terminal type simplifies installation in standard relay sockets and makes troubleshooting faster during service calls. It fits scenarios where a compact, certified relay is needed for control logic or interlock functions.

Key Features

• SPDT contact form supports both normally open and normally closed switching in a single relay
• 12 amp contact rating at 240 VAC for light load switching applications
• 24 VDC coil voltage compatible with common low-voltage control circuits
• Plug-in terminal type allows tool-free relay swap in compatible relay sockets
• CE, CSA, UL Recognized, and RoHS compliant for code-required installations
• Compact footprint at 2.1 x 1.3 x 1.0 inches

Compatibility

Designed as an OEM-style replacement plug-in general purpose relay for use in compatible relay socket bases that accept this form factor and terminal configuration. Verify socket base compatibility before installation.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC controls technician in accordance with applicable NEC requirements. De-energize and lock out the control circuit before removing or inserting the relay. Confirm the socket base matches the relay terminal layout prior to seating the relay. Do not exceed the rated contact current or coil voltage specified for this device.
