HB1-C | Siemens

Why HB1-C?

The HB1-C is a generator circuit-breaker system, an all-in-one bolt-on solution for retrofit projects up to 72 kA. It adapts to power generation applications.

Retrofit projects often struggle with integrating new equipment due to space and design limits. Solve this with the HB1-C's extensive customization—mount it vertically or horizontally, and adjust its I-shape or L-shape design to match existing busbar connections for seamless integration.

The compact dimensions of the HB1-C match legacy GCB interfaces, simplifying upgrades. Reduce operational costs by up to 75% using maintenance-free vacuum technology. Enhance safety and compliance with integrated main-disconnectors and earthing switches, meeting IEC/IEEE 62271-37-013:2021 standards.
