Eaton FAZ-C32/1-NA-SP 32A 1-Pole 277 V Circuit Breaker Current-Limiting Potential Transformer

The Eaton FAZ-C32/1-NA-SP is a compact, high-performance protection device designed for 277 V circuits. This 32 A, 1-pole circuit breaker combines current-limiting capabilities with an integrated potential transformer, delivering both robust overcurrent protection and scalable sensing in a single, space-saving package. Built for commercial and light-industrial environments, it simplifies protection schemes while preserving accurate monitoring of voltage and current.

Why this unique combination matters

In one integrated unit, you get reliable fault interruption and immediate energy control, plus a built-in sensing element that feeds metering and protection relays. The current-limiting feature minimizes fault energy, reducing arcing and component stress during faults, which can extend equipment life and improve overall electrical reliability. The embedded potential transformer provides clean, scaled signals for monitoring and protective relays without needing separate sensing devices, helping you streamline wiring and panel layout.
