Square D 8501KPDR12V51 Octal Relay Dpdt 12 Vdc 10A

Product Description

The SQUARE D 8501KPDR12V51 is an octal electromechanical plug-in general purpose relay designed for industrial and commercial control circuit applications. It operates on a 12 VDC coil and features a DPDT contact form rated at 10 amps at 250 VAC. The relay draws just 3 VA of coil power, making it compatible with low-current control circuits. Its 8-pin octal base allows fast plug-in installation without the need for tooled wire terminations. Horsepower ratings are 1 hp at 277 volts and 1/3 hp at 120 volts, covering a range of small motor and general switching loads. Electricians and control panel builders are the primary installers.

This relay is suited for use in residential, commercial, and light industrial control panels where a socketed DPDT switching element is needed. Typical applications include HVAC control circuits, building automation systems, motor starter logic, and general-purpose switching duty in ladder-logic panels. The plug-in octal format allows quick relay swaps during troubleshooting or routine maintenance without disturbing field wiring connected to the socket.

Key Features

• DPDT contact form provides two independent switched circuits in a single relay body
• 12 VDC coil voltage for compatibility with common low-voltage DC control circuits
• 10 amp contact rating at 250 VAC for reliable general-purpose switching
• 3 VA coil power draw for use with low-current control transformers and PLCs
• Octal plug-in base enables tool-free relay replacement in a standard octal socket
• Meets CE, CSA 22.2 No. 14, UL 508, IEC 61984, and RoHS compliance standards

Compatibility

Designed for use with standard octal relay sockets. Compatible with control systems requiring a DPDT plug-in relay with a 12 VDC coil and 10 amp contact rating at 250 VAC.

Installation Notes

Installation should be performed by a licensed electrician in accordance with NEC requirements and any applicable local codes. De-energize the control circuit and verify the coil voltage matches the relay before inserting into the socket. Align the 8-pin octal base carefully with the socket to avoid bent pins. Do not exceed the rated contact current or voltage during operation.
