Siemens HCP327HT – 800A, 3-Pole Panelboard Switch (Class T) – HCP Series

The Siemens HCP327HT – 800A, 3-Pole Panelboard Switch (Class T) from the proven HCP Series is engineered for the most demanding panelboard and switchboard applications. It delivers reliable load isolation and robust overcurrent protection, acting as a dependable backbone for high-current feeders and main circuits in industrial electrical distributions.

What it delivers and why it matters

In facilities with large three-phase loads, the HCP327HT provides synchronized, complete disconnection of all three phases. This holistic isolation enhances maintenance safety, reduces arc-flash risk, and helps prevent uneven phase conditions during fault clearing. Built to operate under load transients and fault conditions with predictable performance, it stands up to the rigors of continuous industrial service.

Key features and benefits

• 800A current rating supports large feeders and significant load centers, minimizing the need for multiple sectionalizers in demanding facilities.
• Three-pole isolation ensures simultaneous disconnection of all phases, improving maintenance safety and fault response.
• Class T designation reflects Siemens’ stringent design standards for reliability, longevity, and predictable operation in industrial environments.
• Integrated overcurrent protection aligned with industrial requirements, providing dependable protection for panelboards and switchboards.
• Seamless HCP Series integration—works cohesively with other Siemens switchgear components for streamlined installation, service, and system-wide reliability.
• Durable, field-ready construction designed to perform in harsh industrial settings where uptime matters.
