1SKV327041S0001 ABB EPX-CBXT1-4P Protecta Power MCCB Cover Blank XT1 4P 110 mm

Why Choose the ABB EPX-CBXT1-4P Protecta Power MCCB Cover Blank?

The ABB EPX-CBXT1-4P is a purpose-designed moulded case circuit breaker (MCCB) cover blank for use with the ABB Protecta Power electrical distribution system. As part of the ABB Protecta Power Enclosures range, this accessory is designed to cover unused outgoing device positions corresponding to the ABB Tmax XT1 four-pole MCCB format. Identified by ABB order code 1SKV327041S0001, the EPX-CBXT1-4P provides a manufacturer-specified blanking solution for compatible low-voltage distribution panelboards.

The EPX-CBXT1-4P helps electrical contractors, panel builders and maintenance engineers complete outgoing circuit sections where an MCCB position is not occupied. By covering the unused opening, the blanking accessory supports an organised panelboard layout and helps maintain the intended physical separation between the enclosure interior and its accessible front section when correctly installed.

With a manufacturer-specified blanking size of 110 mm, the ABB EPX-CBXT1-4P is matched to the XT1 four-pole MCCB outgoing position within compatible Protecta Power assemblies. It is particularly useful for distribution boards with spare outgoing ways, future circuit expansion requirements or panelboard configurations where selected MCCB positions remain unused.

Reliable MCCB Blanking for Electrical Distribution Panelboards

The ABB Protecta Power range provides a modular approach to low-voltage electrical distribution in commercial buildings and industrial facilities. Its panelboard system accommodates a selection of outgoing moulded case circuit breakers, including devices from the ABB Tmax XT family. The range also includes dedicated mounting accessories, base plates, covers and blanking plates to support different outgoing circuit configurations.

The ABB EPX-CBXT1-4P MCCB cover blank is specifically designed to fill an unused outgoing position corresponding to an XT1 four-pole circuit breaker. ABB specifies a 110 mm blanking size for this accessory. Correctly selected blanking plates help complete the front arrangement of a distribution assembly when a circuit breaker has not been installed in an available outgoing position.

Within the same Protecta Power accessory range, ABB offers the EPX-CBXT1-3P for XT1 three-pole positions with an 80 mm blanking size. Other four-pole alternatives include the EPX-CBXT2-4P at 120 mm, EPX-CBXT4-4P at 140 mm and EPX-CBXT5-4P at 190 mm. These different sizes allow panel builders to select a cover blank matched to the relevant outgoing MCCB position.

The EPX-CBXT1-4P is a mechanical blanking accessory and does not contain an MCCB, trip unit or current-carrying protection device. It should be fitted only to the appropriate unused position in a compatible Protecta Power assembly. Final installation must follow ABB's applicable panelboard assembly instructions, including requirements for covers, accessibility and enclosure protection.
