The ABB VD4/P 12.12.32 Vacuum Circuit Breaker (VCB) is a high-capacity, medium-voltage indoor breaker designed for 11kV systems. It has a rated current of 1250A and a short-circuit breaking capacity of 31.5kA, offering robust protection for power distribution networks.

This model integrates ABB’s advanced vacuum interrupter technology for fast, safe, and arc-free interruption with a long electrical lifespan and reduced maintenance.

The /P suffix indicates a product variant tailored for enhanced panel compatibility. The inclusion of a female socket (L=0.8) allows for quick and secure plug-in connections within modular switchgear systems, facilitating faster installation and maintenance.

Equipped with:

• MO1 – Spring-operated mechanical operating mechanism

• MC – Mechanical interlock for safe operation

• MS – Mechanical shutter protecting live terminals

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

• Female Socket (L=0.8) – Plug-in connector for streamlined switchgear assembly

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