Why Choose the ABB EPX-CBXT1-3P MCCB Cover Blank?
The ABB EPX-CBXT1-3P, manufacturer order code 1SKV327031S0001, is a dedicated MCCB cover blank for ABB Tmax XT1 three-pole circuit breaker positions within compatible ABB Protecta Power electrical distribution enclosures. Designed to cover an unused XT1 3P outgoing device opening, this accessory helps complete the distribution board's front cover arrangement when a circuit breaker is not installed in the designated position.
As part of the ABB Protecta Power Enclosures accessory range, the EPX-CBXT1-3P supports professional low-voltage switchboard assembly, enclosure finishing and circuit configuration changes. Its dedicated XT1 three-pole format allows panel builders to select a blanking component corresponding to the intended MCCB position rather than using a general-purpose cover.
The EPX-CBXT1-3P is a mechanical cover accessory, not a circuit breaker, mounting base or protective device. It is intended for compatible ABB Protecta Power arrangements incorporating outgoing positions designed for ABB Tmax XT1 3P moulded case circuit breakers.

Dedicated Blanking for ABB Tmax XT1 Three-Pole MCCB Positions
Low-voltage distribution boards are often designed with more outgoing circuit breaker positions than are initially required. Where an MCCB position remains unused, a compatible blanking accessory can be fitted to complete the front cover arrangement. The ABB EPX-CBXT1-3P is specifically identified for Tmax XT1 three-pole MCCB positions within the Protecta Power enclosure system.
The ABB Tmax XT1 is a compact moulded case circuit breaker family used in low-voltage distribution applications. Three-pole XT1 devices are designed for three-phase circuit arrangements, and their installation requires appropriately selected mounting and cover components. The EPX-CBXT1-3P serves a different purpose from an MCCB base plate and cover: it is intended to blank an unused device opening, not to mount an operational circuit breaker.
When selecting this accessory, installers should confirm that the existing enclosure has the appropriate XT1 3P cover opening and that the blank is compatible with the specific ABB Protecta Power assembly. The completed cover arrangement must meet the applicable requirements for access to live parts and the enclosure's intended protection characteristics. The cover blank itself does not establish an independent ingress protection or electrical rating.
