Square D 8501CDO16V53 General Purpose Relay Dpdt 24 Vdc

Product Description

The SQUARE D 8501CDO16V53 is an electromechanical general purpose relay designed for industrial and commercial control applications. It operates on a 24 VDC coil voltage and carries a 10 VA power rating. The relay features a DPDT (double-pole, double-throw) contact form with screw clamp terminal connections, providing secure, vibration-resistant wiring terminations. Rated at 40 amps at 277 VAC and 5 amps at 600 V, it handles a broad range of load types. Licensed electricians and control panel technicians are the primary installers of this component in relay panels, motor control circuits, and automation enclosures.

This relay is suited for use in light commercial and industrial control systems where a reliable DPDT switching element is required. With a 1-1/2 hp motor load rating, it is commonly installed in HVAC control panels, conveyor systems, and general-purpose machine control enclosures. Its compact screw clamp design fits standard relay mounting arrangements and is compatible with DIN rail or panel-mount configurations typical in commercial electrical installations.

Key Features

• DPDT contact form supports two independent switched circuits in one relay body
• 24 VDC coil voltage for integration with low-voltage control circuits
• Screw clamp terminals for secure, tool-tightened wire termination
• Rated 40 amps at 277 VAC and 5 amps at 600 V for broad load compatibility
• 1-1/2 hp motor load rating for direct motor switching applications
• RoHS compliant and UL Listed (File E78351); CSA certified (File 218139)

Compatibility

Designed as an OEM-style replacement for general purpose electromechanical relay applications requiring a DPDT configuration with 24 VDC coil voltage and screw clamp termination.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the NEC and applicable local codes. De-energize and lock out the control panel before removing or installing the relay. Screw clamp terminals require a small flat-blade screwdriver for proper wire seating and should be torqued to the terminal manufacturer specifications found in the product documentation. Confirm coil voltage supply matches the 24 VDC rating before energizing the circuit.
