Square D 8501RSD42V53 General Purpose Relay Dpdt 24 Vdc

Product Description

The SQUARE D 8501RSD42V53 is an electromechanical plug-in general purpose relay rated for 10 amps at 240 volts AC with a 24-volt DC coil. It features a double-pole double-throw (DPDT) contact form, making it suitable for switching two independent circuits simultaneously. The plug-in terminal design allows for fast installation and replacement without hardwiring. Licensed electricians and HVAC technicians commonly install this relay in control panels, motor control circuits, and low-voltage switching applications. It carries CE, CSA, UL Recognized, and RoHS Compliant certifications.

This relay is used in residential and light commercial control circuits where reliable electromechanical switching is required. Typical applications include HVAC control boards, industrial automation panels, building automation systems, and general-purpose relay panels. The 24-volt DC coil voltage is common in low-voltage HVAC and building control circuits. Its plug-in form factor suits relay sockets and panel-mounted relay bases, making it a practical replacement component in existing control assemblies.

Key Features

• 10-amp contact rating at 240 volts AC for reliable load switching
• DPDT contact form switches two circuits from a single coil signal
• 24-volt DC coil compatible with standard low-voltage control circuits
• Plug-in terminal type for tool-free insertion and fast field replacement
• CE, CSA, UL Recognized, and RoHS Compliant certifications

Compatibility

Designed as an OEM-style plug-in replacement relay for use in relay sockets and control panels accepting DPDT plug-in relays with a 24-volt DC coil and 10-amp contact rating.

Installation Notes

Installation should be performed by a licensed electrician or qualified HVAC technician in accordance with the NEC and applicable local codes. De-energize and lock out the control panel before removing or inserting the relay. Verify the socket base accepts a DPDT plug-in relay and that the coil voltage supply matches the 24-volt DC rating before energizing. Do not exceed the 10-amp contact rating for the connected load.
