Square D 8501CO16V24 General Purpose Relay Dpdt 240 Vac

Product Description

The SQUARE D 8501CO16V24 is a double-pole double-throw (DPDT) electromechanical general purpose relay rated for 10 VA coil power and 240 VAC coil voltage at 50/60 Hz. Built with screw clamp terminal connections, this relay provides secure, vibration-resistant wiring terminations suited to industrial and commercial control panel applications. Contact ratings reach 40 amps at 277 VAC and 5 amps at 600 V, covering a wide range of switching loads. At 2.6 inches wide, 2.4 inches high, and 3.2 inches deep, it fits standard enclosure footprints without modification. Licensed electricians and controls technicians are the primary installers of this device.

This relay is appropriate for commercial and light industrial control circuits where DPDT switching logic is required. Typical applications include HVAC control panels, motor starter auxiliary circuits, machine control interlocks, and building automation systems. The 240 VAC coil voltage makes it compatible with standard single-phase control power found in many commercial mechanical rooms and electrical panels. Its compact screw clamp design also suits retrofit and replacement work in existing relay sockets or panel assemblies.

Key Features

• DPDT contact form supports two independently switched circuits from a single coil
• Screw clamp terminals provide vibration-resistant, tool-secured wire termination
• 10 VA coil power rating at 240 VAC, 50/60 Hz for broad coil compatibility
• Contact rating of 40 amps at 277 VAC for substantial load switching capacity
• RoHS compliant and UL Listed (File E78351); CSA certified (File 218139 Class 3211 04)
• Compact footprint at 2.6 x 2.4 x 3.2 inches for standard panel integration

Compatibility

Designed as an OEM-style general purpose control relay for use in commercial and industrial control panel applications requiring a 240 VAC DPDT electromechanical relay with screw clamp termination.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements and local codes. De-energize and lock out the control panel before removing or installing this relay. Verify coil voltage matches the control circuit supply before energizing. Confirm wire gauge and terminal torque specifications meet the panel documentation and applicable code requirements.
