Square D 8501RSD14P14V53 General Purpose Relay 4PDT

Product Description

The SQUARE D 8501RSD14P14V53 is an electromechanical plug-in general purpose relay rated for 5 amps at 240 volts AC with a 24-volt DC coil and a 4PDT contact configuration. This relay operates as a switching device in control circuits, directing low-voltage signal inputs to higher-power output loads. It is designed for plug-in installation, making it a practical choice for panel-mount relay sockets in industrial and commercial control applications. Electricians and controls technicians install this type of relay in automation panels, HVAC control circuits, and machine logic wiring. The 4PDT configuration provides four independently switched poles, offering flexibility in circuit design. Certifications include CE, CSA, UL Recognized, and RoHS compliance.

This relay fits residential and commercial HVAC systems, building automation panels, motor control centers, and general industrial control enclosures where a compact plug-in relay is required. The 24-volt DC coil voltage is common in low-voltage control circuits found in heating and cooling systems, lighting controls, and programmable logic controller output stages. Its plug-in terminal type allows for fast field replacement without rewiring the socket.

Key Features

• 4PDT contact form provides four poles of double-throw switching in a single relay body
• 5-amp contact rating at 240 volts AC suits a wide range of control-circuit load types
• 24-volt DC coil operates directly from common low-voltage control power supplies
• Plug-in terminal type enables fast swap-out from a compatible relay socket without rewiring
• Meets CE, CSA, UL Recognized, and RoHS standards for use in commercial and industrial installations

Compatibility

Designed as an OEM-style plug-in general purpose relay for use in compatible relay sockets accepting a 4PDT plug-in body of this form factor. Verify socket compatibility by contact arrangement and pin layout before installation.

Installation Notes

Installation is typically performed by a licensed electrician or qualified controls technician. De-energize the control panel and verify the circuit is at zero voltage before removing or inserting the relay. Confirm that the relay socket pin layout matches the 4PDT configuration of this relay body before seating. Follow applicable NEC guidelines for control wiring and panel assembly.
