Product Identity

The Eaton XTPAXCLKA4 is a three-phase commoning link designed to connect up to four compatible devices within an electrical panel. It serves installers and maintenance teams who need a factory-made busbar for distributing 63 A AC current across multiple XT-series units.

Sustained Load Behaviour

Rated for 63 A AC continuous current, the link maintains its cross-section without derating when mounted in a Frame Size B enclosure. The transparent housing allows visual confirmation of conductor seating while the 8.100 mm² conductor area handles prolonged thermal stress without hotspots.

Upgrade Context

This accessory replaces field-fabricated copper jumpers that require cutting, bending and insulation taping on site. The jump is worthwhile when panel build time must be reduced, when repeatable torque values are specified, or when inspection standards demand a listed component rather than a handmade connection.

Questions about this item

How much heat or noise does the XTPAXCLKA4 commoning link generate when running continuously at 63 A?

As a passive busbar accessory it has no moving parts or electronics, so it produces no audible noise and negligible heat beyond normal conductor losses at its rated current.

What existing Eaton XT-series components are required to install this 3-phase 4-device commoning link?

It is designed to connect up to four compatible Eaton XT frame-size B devices such as circuit breakers or switch-disconnectors that share the same mounting footprint.

Will the .5 in high by 1.5 in wide link fit alongside older Eaton XT frame-size B breakers already mounted in my panel?

Yes, the commoning link matches the standard XT frame-size B profile, so it aligns with existing breakers of that frame size without requiring panel modifications.
