Square D 8501XB20 Relay Latch Attachment 600V

Product Description

The SQUARE D 8501XB20 is a relay latch attachment designed to provide mechanical latching functionality for compatible relay assemblies. Rated at 600 volts AC, this attachment locks a relay in its energized or de-energized state without requiring continuous coil power, making it well suited for control panel applications where holding current is a concern. Licensed electricians and industrial control technicians typically install this accessory when configuring relay-based logic circuits that require a maintained contact state. It is a direct add-on component, not a standalone relay.

This latch attachment is intended for use with Type X relays in industrial and commercial control applications. It is commonly installed in motor control centers, machine control panels, and process automation enclosures where relay latching is required as part of the control logic. The compact form factor keeps panel layout clean when multiple relay positions are used side by side.

Designed for use with SQUARE D Type X relays as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified electrician in accordance with the National Electrical Code (NEC) and applicable local codes. De-energize and lock out the control panel before attaching or removing relay accessories. Confirm that the relay type and voltage rating of the panel circuit are compatible with this attachment before installation. Do not force the latch mechanism onto relay assemblies outside the specified Type X series.
