Why Choose the ABB PVBX4423 XT4 Fixed 4-Pole RCD Installation Kit?
The ABB PVBX4423 is a purpose-designed vertical installation kit for 4-pole fixed Tmax XT4 circuit-breakers with residual current devices (RCDs). Part of the ABB System pro E Power distribution board system, this kit provides the mounting components required to integrate a compatible XT4 circuit-breaker and residual current protection arrangement into a low-voltage electrical switchboard.
Engineered for professional electrical panel builders and switchboard manufacturers, the PVBX4423 supports a structured and secure installation of circuit-breaker equipment. Its dedicated mounting components simplify assembly, promote consistent equipment positioning and help maintain an organised internal switchboard layout.
Designed for 400 mm-wide switchboard compartments, the PVBX4423 accommodates a 4-pole fixed XT4 circuit-breaker with RCD configuration in a vertical installation arrangement. The kit is specified for a 400 mm-high compartment, making it suitable for modular electrical distribution assemblies using ABB System pro E Power components.

Reliable Circuit-Breaker Integration for Electrical Distribution Systems
The ABB PVBX4423 provides a dedicated mounting arrangement for integrating a fixed, 4-pole Tmax XT4 circuit-breaker with residual current protection into a System pro E Power switchboard. Its vertical installation format supports efficient use of the available compartment space while helping panel builders maintain a consistent and accessible internal equipment layout.
The installation kit includes dedicated fixing brackets, a mounting plate and internal panels with quarter-turn fasteners. These components support mechanical installation and alignment of the circuit-breaker assembly within the distribution board. The PVBX4423 is a mounting accessory rather than a complete circuit-breaker or residual current protection device; the compatible protective equipment must be selected separately according to the electrical installation requirements.
Typical Applications
- ABB System pro E Power low-voltage switchboards.
- Main electrical distribution boards in commercial and industrial facilities.
- Vertical installation of fixed 4-pole Tmax XT4 circuit-breakers.
- Switchboard compartments incorporating residual current protection equipment.
- Electrical distribution panel manufacturing and assembly.
- Industrial electrical infrastructure and power distribution systems.
- Modular switchboard construction and equipment integration.
- Electrical panel upgrades and compatible switchboard modifications.
