Eaton NSB XTCEXMLD Mechanical Interlock Accessory

The Eaton NSB XTCEXMLD Mechanical Interlock Accessory is a purpose-built component designed to integrate with Eaton’s NSB XTCEXMLD starter and contactor assemblies, adding reliable mechanical interlock functionality to paired devices. Intended for use within the NSB XTCEXMLD Starter and Contactor Accessories lineup, this interlock provides a physical lock between related components to support correct sequencing and safer operation in motor control circuits. In panel installations, it helps enforce proper engagement order between a starter and its companion contactor, reducing the risk of incorrect actuation in dual-device configurations. Typical applications include electrical control panels and switchgear that deploy NSB XTCEXMLD equipment whenever interlocked operation is required to prevent simultaneous energization. This accessory is a focused, manufacturer-backed solution for implementing interlock behavior within Eaton’s NSB XTCEXMLD system, avoiding the need for ad hoc modifications and helping maintain consistent electrical safety practices.
