Square D 8501RS42V14 General Purpose Relay Dpdt 10A 24VAC

Product Description

The SQUARE D 8501RS42V14 is an electromechanical plug-in general purpose relay designed for control circuit switching in commercial and industrial electrical applications. It features a double-pole double-throw (DPDT) contact form with a 10 amp rating at 240 VAC and a 24 VAC coil rated for both 50 Hz and 60 Hz operation. The plug-in terminal type simplifies installation and replacement without rewiring the socket base. Motor load ratings are 1/2 hp at 240 volts and 1/3 hp at 120 volts, making it suitable for light motor control duties. Licensed electricians and HVAC controls technicians are the typical installers for this class of relay.

This relay fits general purpose control panel and equipment relay socket applications across commercial HVAC systems, industrial control panels, and building automation circuits. Its compact footprint and plug-in design make it a common choice for relay logic boards, fan coil units, and low-voltage control circuits where a DPDT switching function is required at a 24 VAC coil voltage. The 50/60 Hz dual-frequency rating suits both domestic and international control circuit applications.

Key Features

• DPDT contact form provides two independent switching circuits in one relay body
• 10 amp contact rating at 240 VAC handles light resistive and motor loads
• 24 VAC coil voltage compatible with standard low-voltage HVAC control circuits
• Plug-in terminal type allows fast field replacement without disturbing socket wiring
• Motor load rated: 1/2 hp at 240 volts, 1/3 hp at 120 volts
• Meets CE, CSA, UL Recognized, and RoHS compliance standards

Compatibility

Designed as an OEM-style plug-in replacement relay for general purpose relay sockets accepting DPDT plug-in relays with a 24 VAC coil in commercial HVAC, industrial control, and building automation panel applications.

Installation Notes

Installation should be performed by a licensed electrician or qualified controls technician in accordance with the NEC and applicable local codes. De-energize and lock out the control panel before removing or inserting the relay. Verify the socket base pin configuration matches the 8501RS42V14 before seating the relay. Do not exceed the rated contact current or motor horsepower load for the relay contacts.
