Eaton / Cutler-Hammer FAZ-D1/3-NA Miniature Circuit Breaker

The D curve indicates a magnetic trip point between 10 and 20 times the rated current. This makes it ideal for highly inductive loads with significant inrush currents, such as motors, transformers, and power supplies, preventing nuisance tripping during startup.

Yes, the -NA suffix designates this breaker as UL 489 listed for branch circuit protection. It can be used in applications where UL 1077 supplementary protectors are allowed, but it provides full branch circuit protection for industrial control panels and feeder circuits.

This miniature circuit breaker snaps directly onto a standard 35mm DIN rail. It features a trip-free design and can be fed from either the line or load side for flexible panel wiring.

Yes, this breaker is current limiting. It interrupts fault currents within one half cycle, which significantly reduces the peak let-through energy and provides superior protection for downstream circuit components.

The breaker includes a color-coded visual position indicator on the front face. It displays red when the contacts are closed (ON) and green when the contacts are open (OFF), ensuring safe isolation verification.

Yes, this breaker is dual-rated for both AC and DC applications. It supports up to 96VDC with a 10kA interrupting rating, making it suitable for various control instrumentation and DC power supply circuits.

This model comes equipped with standard box lug terminals that accept conductors ranging from 18 AWG to 6 AWG. The captive screw design ensures the terminal screws cannot be lost during installation or maintenance.
