Eaton FAZ-B63/2 63A 2-Pole 240 V Circuit Breaker Potential Transformer

Meet the Eaton FAZ-B63/2 — a dependable 63-amp, two-pole circuit breaker designed for 240-volt distribution in commercial and industrial panels. As a genuine Eaton part (FAZ-B63/2), it delivers precise protection and compatibility within Eaton’s protection ecosystem, including configurations that integrate with potential transformer monitoring where required.

Key specifications at a glance

• Current rating: 63 A
• Poles: 2
• Voltage rating: 240 V
• Part number: FAZ-B63/2
• Type: Circuit breaker, two-pole protection
• Safety benefit: Simultaneous disconnection of both conductors for enhanced safety during faults

Why this model stands out

• Precise overcurrent protection: The 63 A rating is ideal for feeding medium-load circuits, preventing wiring damage and equipment failure due to overload.
• Dual-pole reliability: With two poles, the device interrupts both live conductors together, reducing arc and ensuring safer shutdown behavior in fault conditions.
• Built for Eaton environments: Designed to integrate smoothly with Eaton panelboards, switchgear, and protective schemes, providing predictable performance and ease of replacement.
• Compatibility with sensing systems: The model name hints at compatibility within protection setups that may use potential transformer monitoring, helping your system achieve coordinated protection in larger installations.

Ideal use cases

• Feeder protection for commercial spaces such as offices, retail centers, and data rooms where 240 V distribution is standard.
• Motor control feeders and distribution circuits requiring reliable two-pole disconnection at 63 A max.
• Replacement or retrofits in existing Eaton panels and switchgear that call for the FAZ-B63/2 specification.
• New installations that prioritize Eaton’s proven protection ecosystem and straightforward maintenance.

Practical guidance and value

For best results, install by following standard electrical practices and the manufacturer’s torque and wiring guidelines. The two-pole design helps ensure safe, synchronized tripping, which can reduce downtime and protect downstream equipment. When planning installations that involve protection relays or monitoring instrumentation, consider configurations that leverage potential transformer sensing to optimize protection coordination.
