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.
