Eaton FAZ-D16/1-SP Circuit Breaker

The D curve indicates a high magnetic trip point designed for applications with high inrush currents. This prevents nuisance tripping in highly inductive loads like motors, transformers, and power supplies.

No. The FAZ series is recognized under UL 1077 as a supplementary protector. It is designed for use within appliances or electrical equipment where branch circuit protection is already provided or not required. For UL 489 branch circuit protection, an Eaton FAZ-NA series breaker is required.

This device snaps onto a standard 35mm DIN rail. It features a compact module width of 17.5mm per pole and allows power to be fed from either the line or load side.

The -SP suffix indicates that the supplementary protector is sold in a single package. Eaton uses this designation for single-pole breakers in select amperages that are individually packaged.

Yes. The breaker features a color-coded contact position indicator that provides immediate visual status. It displays red when the contacts are closed and green when they are open. It also utilizes a trip-free mechanism, meaning the breaker will trip under a fault even if the handle is held in the ON position.

Yes. Eaton FAZ series supplementary protectors feature a current-limiting design. This provides fast short-circuit interruption that reduces the peak let-through energy, helping to prevent damage to the downstream circuit.
