Square D 8501RS42P14V20 Relay Overview

The Square D 8501RS42P14V20 is a general-purpose relay designed for industrial electrical controls and automation. It features a square base with an 8-pin flat quick-connect socket mounting style. The unit operates on a 120V AC coil voltage and provides DPDT contact form with a 15 A current rating. A transparent enclosed body includes an LED status indicator and a mechanical flag for visual monitoring.

Suited Applications and Limitations

This relay suits control panels and automation systems requiring 15 A switching at 120V or 277V AC and 28V DC. It also handles motor loads up to 1/2 hp at 120V AC and 1/10 hp at 240V AC. Installers needing a push-to-test button for manual actuation should look elsewhere, as this model has no button. Applications requiring higher coil voltages or different pin configurations are not supported.

Capacity and Headroom

The contact ratings provide headroom for 15 A resistive loads across 120V AC, 277V AC, and 28V DC circuits. Motor loads are limited to 1/2 hp at 120V AC and 1/10 hp at 240V AC. The 0.18 in flat pins fit standard 8-pin sockets, while the 1.4 in body depth and 2.09 in height determine enclosure clearance. Circuits exceeding these voltage, current, or horsepower ratings will exceed the relay's capacity.

Questions about this item

Which socket accepts the 8-pin flat-pin base on the 8501RS42P14V20?

The relay uses an 8-pin square socket with 0.18 in flat pins, so a matching 8-pin square-base socket is required for installation.

Will the 120V AC coil operate correctly on a 240V AC control circuit?

No, the coil is rated for 120V AC only; applying 240V AC would exceed the coil voltage and could damage the relay.

How do I verify the relay is switching after wiring it up?

The built-in LED indicator lights when the 120V AC coil is energised, and the mechanical flag moves to show contact position.
