1SKV327035S0001 ABB EPX-CBXT5-3P Protecta Power MCCB Cover Blank XT5 3P 140 mm

Why Choose the ABB EPX-CBXT5-3P MCCB Cover Blank?

The ABB EPX-CBXT5-3P is a purpose-designed three-pole moulded case circuit breaker (MCCB) cover blank for ABB Protecta Power electrical distribution panelboards. As part of the ABB Protecta Power Enclosures range, this accessory is specifically developed to cover unused outgoing positions corresponding to ABB Tmax XT5 three-pole circuit breakers, helping maintain a neat, professional and appropriately enclosed low-voltage distribution assembly.

Designed for electrical contractors, switchgear manufacturers and panel builders, the EPX-CBXT5-3P provides a dedicated blanking solution for vacant XT5 three-pole outgoing device positions. Its frame-specific design allows installers to cover an unused circuit breaker opening without fitting an unnecessary MCCB, supporting the modular construction and flexible configuration of ABB Protecta Power panelboards.

With a three-pole (3P) XT5 configuration and an ABB-specified 140 mm nominal blanking size, the EPX-CBXT5-3P is suitable for compatible Protecta Power outgoing sections. Identified by ABB order code 1SKV327035S0001, this genuine ABB accessory is intended for commercial and industrial electrical distribution installations where unused MCCB positions require a correctly sized cover blank.

Reliable MCCB Blanking Solutions for Electrical Distribution Panelboards

Electrical distribution panelboards frequently include spare outgoing circuit breaker positions to accommodate future circuit additions, system modifications or changes in electrical demand. Where these positions are not occupied by an MCCB, suitable blanking accessories are used to close the unused openings and support the intended enclosure arrangement.

The ABB EPX-CBXT5-3P is specifically designed for this purpose within the ABB Protecta Power distribution system. Its 140 mm nominal blanking size corresponds to the space allocated to an ABB Tmax XT5 three-pole outgoing device, allowing the vacant position to be covered without installing a circuit breaker.

ABB Protecta Power panelboards feature modular outgoing device arrangements accommodating different circuit breaker frames and pole configurations. The manufacturer's MCCB cover blank range includes dedicated versions for A1, XT1, XT2, XT4 and XT5 device positions, allowing installers to select a blanking accessory appropriate to the circuit breaker opening.

For comparison, the ABB Protecta Power range specifies nominal cover blank sizes of 80 mm for XT1 3P, 100 mm for XT2 3P, 110 mm for XT4 3P and 140 mm for XT5 3P. The corresponding XT5 four-pole cover blank has a nominal size of 190 mm. Selecting the correct frame-specific and pole-specific blank helps maintain an organised panelboard layout and supports future expansion of the distribution system.

When correctly fitted to a compatible panelboard, the EPX-CBXT5-3P helps close the unused front opening and contributes to the enclosure's protective arrangement. The completed assembly's ingress protection and accessibility requirements depend on the panelboard design, correct installation and ABB assembly instructions. This accessory is a mechanical blanking component and does not independently provide electrical switching, isolation, overload protection or short-circuit protection.
