PXD63B160 - 1600 Amp Circuit Breaker

PXD63B160 - 1600 Amp Circuit Breaker

Built for heavy‑duty electrical installations, the Siemens PXD63B160 is a high‑capacity 3‑pole molded‑case circuit breaker engineered to deliver dependable protection for industrial and large‑scale commercial power systems. With a 1600A rating and a thermal‑magnetic trip unit, this breaker gives you accurate overload and short‑circuit protection when it matters most. Whether you’re upgrading an existing panel or designing a new distribution setup, the PXD63B160 offers the performance and compliance you need to keep things running smoothly and safely.

Key Features and Benefits

• Thermal‑Magnetic Trip Unit: Combines thermal overload detection with magnetic short‑circuit protection for precise interruption of dangerous fault conditions.
• High Interruption Capacity: Handles fault currents up to 25 kAIC at 600 V and 50 kAIC at 480 V, giving you strong fault‑current protection for demanding electrical systems.
• Non‑Interchangeable Trip Mechanism: Helps ensure system integrity by preventing unauthorized or accidental changes to the trip settings.
• 3‑Pole, 1600A Capacity: Designed for large-scale installations, delivering consistent power demand support without unnecessary system stress.
• Heavy‑Duty Frame (PD Frame): Built to accommodate the load and environmental demands typical of industrial and commercial power distribution setups.
