Description

Rated for 15 amps at 277VAC, this single-pole miniature circuit breaker provides essential protection for commercial, industrial, and marine motor control circuits. It fastens onto standard DIN rail systems and acts as a seamless replacement for the legacy WMZT1D15 model. The D-curve thermal-magnetic trip technology allows for high inrush currents without nuisance tripping. This UL 489 listed component also includes SWD and HACR ratings, along with a convenient visual trip indicator.

Product FAQs

8 answers
What does the D trip curve signify on the FAZ-D15/1-NA-SP?

The D curve indicates a magnetic trip point of 10 to 20 times the rated current. This high threshold prevents nuisance tripping in applications with significant inrush currents, such as motors, transformers, and highly inductive loads.

Is the Eaton FAZ-D15/1-NA-SP approved for branch circuit protection?

Yes. The FAZ-NA series is UL 489 listed, which qualifies it for branch circuit protection in industrial control panels and equipment. It can be used in place of UL 1077 supplementary protectors.

What type of mounting hardware is required for this breaker?

This miniature circuit breaker snaps directly onto a standard 35mm DIN rail inside control cabinets and enclosures.

Does this breaker feature a trip-free mechanism?

Yes. The internal trip-free design ensures the breaker will open the circuit during an overcurrent or short-circuit event, even if the toggle handle is physically held in the ON position.

Can I install the FAZ-D15/1-NA-SP in a standard residential load center?

No. This is a DIN rail mounted breaker designed specifically for industrial control panels and automation enclosures. It will not fit into plug-on or bolt-on residential panelboards.

What does the -SP suffix mean in the catalog number?

The -SP suffix indicates that the breaker is packaged as a single unit (Single Pack) rather than in bulk quantities for OEMs.

Is the FAZ-NA series considered current limiting?

Yes. The current-limiting design interrupts fault currents within one-half cycle. This rapid response reduces peak let-through energy, offering superior protection for sensitive downstream components.

Can power be fed from either direction on the FAZ-D15/1-NA-SP?

Yes. Power can be supplied to either the line or load side terminals. The breaker is reverse-feed capable without compromising its protective functions or safety ratings.
