Eaton FAZ-S10/2 10A 2-Pole 400 V Circuit Breaker Potential Transformer

Meet the Eaton FAZ-S10/2 10A 2-Pole 400 V Circuit Breaker Potential Transformer — a purpose-built protection device designed to safeguard industrial and commercial electrical panels. With a 2-pole configuration and a 400 V rating, this unit delivers reliable disconnect capability across both conductors, helping keep wiring and connected equipment safe during faults. Its compact form and compatibility with Eaton’s protection and metering ecosystem make it a practical upgrade for panels that demand precise protection and accurate monitoring.

Key advantages that matter in real-world installations

• Dual-pole protection — interrupts both live conductors to prevent hazardous backfeed and ensure comprehensive circuit isolation at 400 V systems.
• 10 A current rating — ideal for protecting smaller distribution circuits, control circuits, or motor protection on shared feeders without oversizing the protection device.
• Compatibility with Eaton ecosystem — designed to integrate smoothly with Eaton protection relays, metering equipment, and related accessories for a consolidated control and monitoring solution.
• Reliable performance — engineered for consistent trip response and dependable operation in demanding environments found in industrial settings, commercial facilities, and data-center auxiliary circuits.
• Space-conscious design — a compact footprint that fits standard panel spaces, enabling more efficient panel builds and easier retrofits.

Use cases and practical applications

• Main distribution panels where 400 V three-phase or two-phase feeds require robust overcurrent protection with simultaneous disconnect of both lines.
• Motor control centers and feeder circuits where 10 A protection provides precise current limiting for smaller motors or control gear.
• Panel retrofits or new installations in facilities using Eaton protection and metering components, enabling streamlined diagnostics via compatible potential-transformer interfaces.
• Commercial and light-industrial electrical boards that demand reliable protection without unnecessary downtime due to nuisance trips.

What you gain with the FAZ-S10/2

• Clear protection strategy — consistent disconnection behavior reduces arc exposure and helps protect cables, devices, and personnel.
• Operational clarity — when paired with compatible monitoring equipment, you can track current flow and fault conditions to inform preventative maintenance.
• Efficient panel planning — the 2-pole, 400 V profile fits common industrial distribution schemes, enabling neat, orderly panel layouts.

Whether you’re upgrading an aging panel, expanding a distribution network, or deploying a new control system, the Eaton FAZ-S10/2 10A 2-Pole 400 V Circuit Breaker Potential Transformer delivers precise protection, straightforward integration, and dependable performance. Rely on its targeted specifications — current rating of 10 A, two poles, and 400 V voltage rating — to keep your circuits safeguarded while maintaining clear visibility into your electrical protection strategy.
