Product FAQs

7 answers
What does the D trip curve signify for this Eaton FAZ miniature circuit breaker?

The D-curve magnetic trip point operates at 10 to 20 times the rated current. This makes it ideal for highly inductive loads, transformers, and motors where high inrush currents are expected during startup.

Is the FAZ-D4/2-NA rated for branch circuit protection?

Yes, the FAZ-NA series is UL 489 listed for branch circuit protection. It can also be used in applications where UL 1077 supplementary protection is allowed.

How is the FAZ-D4/2-NA circuit breaker installed in a control panel?

This breaker is designed for installation on a standard 35mm DIN rail using a spring clip mechanism.

Is this Eaton circuit breaker considered current limiting?

Yes, the FAZ-NA series features a current-limiting design. It interrupts fault currents quickly to reduce the peak let-through energy that could otherwise damage the circuit.

Can the breaker be held in the ON position during a fault?

No, it features a trip-free mechanism. The breaker will trip and disconnect the power supply during an overload or short circuit even if the handle is physically held in the ON position.

Does this breaker have a contact position indicator?

Yes, it includes a color-coded visual indicator on the front. Red indicates the contacts are closed, and green indicates the contacts are open.

Can the Eaton FAZ-D4/2-NA be reverse fed?

Yes, these DIN rail miniature circuit breakers are suitable for reverse feed wiring configurations.
