The ABB VD4/P 12.12.25 Vacuum Circuit Breaker (VCB) is a high-performance indoor medium-voltage breaker rated at 11kV, 1250A, with a short-circuit breaking capacity of 25kA. This model incorporates ABB's proven vacuum interrupter technology to ensure safe, arc-free interruption and long operational life.

The /P designation refers to a specific variant designed for easy integration with modern switchgear panels. The inclusion of a female socket (L=0.8) facilitates secure plug-in connections, enabling faster installation and maintenance.

Equipped with:

• MO1 – Spring-charged mechanical operating mechanism

• MC – Mechanical interlock system for safe operation

• MS – Mechanical shutter protecting live parts

• BB1-2 – Busbar and interlocking modules for panel integration

• Female Socket (L=0.8) – Plug-in connection for compact switchgear assemblies

Ideal for utilities, industrial plants, and commercial infrastructure requiring reliable high-capacity breakers with compact and modular designs.
