Square D 8501KPR13P14V20 General Purpose Relay 3PDT

Product Description

The SQUARE D 8501KPR13P14V20 is a 3PDT octal plug-in electromechanical relay rated for general-purpose control applications. It features 11 pins in an octal base configuration and operates on a 120 VAC coil at 50/60 Hz with a 3 VA power draw. Contacts are rated at 10 amps at 250 VAC, with motor load ratings of 1 hp at 277 volts and 1/3 hp at 120 volts. Licensed electricians and HVAC controls technicians install this relay in low-voltage control panels, motor control circuits, and automated switching applications. The plug-in design simplifies replacement without rewiring the socket base.

This relay is suited for residential and light commercial control systems where a socketed, replaceable relay is required. Typical applications include HVAC control panels, industrial automation cabinets, and building automation switching circuits. The 3PDT contact arrangement allows three separate circuits to be switched simultaneously from a single coil, making it useful in sequencing and interlock logic. It is designed to mount in a standard 11-pin octal relay socket, which must be ordered separately if not already installed.

Key Features

• 3PDT contact form switches three independent circuits from one coil
• 11-pin octal plug-in base for tool-free relay replacement in compatible sockets
• 120 VAC coil at 50/60 Hz with a 3 VA coil power rating
• 10 amp contact rating at 250 VAC for resistive loads
• Motor load ratings: 1 hp at 277 volts, 1/3 hp at 120 volts
• Certified to UL 508, CSA 22.2 No. 14, IEC 61984, CE, and RoHS Compliant

Compatibility

Designed as an OEM-style plug-in replacement for 11-pin octal general-purpose relay sockets in HVAC control panels and industrial switching applications. A compatible 11-pin octal relay socket base is required for installation and must be sourced separately.

Installation Notes

Installation should be performed by a licensed electrician or qualified controls technician. De-energize and lock out the control panel before removing or inserting the relay. Verify the socket base pin configuration matches the 11-pin octal layout before seating the relay. Follow applicable NEC requirements for control circuit wiring and panel assembly.
