Eaton XTCEXMLD Mechanical Interlock Accessory

Product Description

The EATON XTCEXMLD is a mechanical interlock accessory designed for use with compatible EATON contactor assemblies. Mechanical interlocks physically prevent two contactors from engaging simultaneously, providing a reliable hardware-level safety mechanism in reversing or transfer switching applications. Electricians and panel builders install this accessory to enforce exclusive operation between paired contactors without relying solely on control-circuit logic. It mounts directly between two contactors and couples their actuator mechanisms so that closing one contactor mechanically blocks the other from closing.

This interlock is suited for industrial and commercial electrical control panels where motor reversing starters, transfer switches, or other dual-contactor configurations require positive mechanical lockout. It is used in applications where a single phase or three-phase motor must be switched between two sources or directions of rotation. The XTCEXMLD is an add-on accessory and does not include contactors; it installs as part of a matched contactor pair in a control assembly.

Key Features

• Provides positive mechanical lockout between two paired contactors
• Prevents simultaneous energization of both contactors at the hardware level
• Add-on accessory design mounts directly to compatible EATON contactors
• Supports reversing starter and transfer switching applications
• Supplements control-circuit interlocking for increased reliability

Compatibility

Designed as an OEM-style add-on accessory for compatible EATON contactor assemblies used in reversing or dual-contactor control panel configurations. Consult EATON documentation to confirm contactor frame size compatibility before installation.

Installation Notes

Installation should be performed by a licensed electrician in accordance with applicable NEC requirements and the equipment manufacturer instructions. De-energize and lock out the control panel before installing or removing the interlock accessory. Confirm that both contactors in the pair are compatible with this interlock before assembly. Do not energize the circuit until the interlock is fully seated and secured per the manufacturer guidelines.
