Siemens HCP328HT – 1200A, 3-Pole Panelboard Switch (Class T) – HCP Series

Engineered for the most demanding industrial power routes, the Siemens HCP328HT 1200A, 3-Pole Panelboard Switch (Class T) from the HCP Series is a purpose-built solution for serious load isolation and robust overcurrent protection. Designed to live in panelboards and switchboards, it delivers reliable performance where uptime and safety matter most.

Why the HCP328HT stands out

With a true 1200-ampere rating across three poles, this switch is built to handle high‑current, three‑phase feeders without compromise. The Class T construction is tailored for harsh industrial environments, delivering dependable interruption when faults occur while resisting wear from continuous operation. As part of the Siemens protection family, it integrates smoothly into existing protection schemes and distribution architectures, reducing integration friction and enabling consistent protection across the facility.

What it does for your operation

• High-current reliability: 1200 A in a 3‑pole configuration ensures heavy loads and motor circuits can be isolated cleanly without derating.
• Rugged Class T protection: Built to withstand industrial conditions, providing durable fault interruption when and where it’s needed.
• Panelboard and switchboard readiness: Seamless compatibility with standard distributions and Siemens protection ecosystems for straightforward installation and maintenance.
• Safe load isolation: Fast, dependable disconnection safeguards downstream equipment and minimizes fault propagation.
• Precise overcurrent handling: Clear interruption characteristics minimize stress on downstream gear during fault events.
• Scalable, durable architecture: Designed to support expansion within larger distributions while preserving performance consistency.

Ideal for

Electrical engineers, panel builders, and maintenance teams who manage facilities relying on heavy 3‑phase power will find the HCP328HT indispensable. It’s well suited for data centers, manufacturing floors, and large commercial or institutional buildings where a single, reliably isolating 3‑pole switch must safeguard critical circuits and maintain uptime under fault conditions.

Practical deployment tips

• Plan for full three‑phase isolation during maintenance to ensure complete de‑energization of targeted circuits.
• Coordinate with upstream protection devices to calibrate protection curves around the 1200 A capacity for optimal selectivity and minimal disruption.
• Schedule periodic inspections of linkage and terminal connections to sustain reliable operation in high‑load environments.
• Align integration with your existing Siemens protection ecosystem to simplify diagnostics, serviceability, and spare‑part compatibility.

Why choose this solution over lighter‑duty options

The HCP328HT is purpose‑built for industrial‑scale power distribution. Its 1200A three‑pole capability paired with Class T robustness provides a dependable, long‑term foundation for demanding applications.
