Description

Designed for commercial and industrial applications, this single-pole 8A miniature breaker provides reliable protection for highly inductive circuits. It installs into standard DIN rail systems and industrial control panels, replacing the older FAZ-D8/1-NA model. The D-curve trip characteristic handles high inrush currents typical of motors and transformers, while the current-limiting design ensures enhanced safety and compliance with UL 489 standards.

Product FAQs

7 answers
What does the D curve signify on the FAZ-D8/1-NA-SP?

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

Is the FAZ-D8/1-NA-SP rated for branch circuit protection?

Yes, the FAZ-NA series is UL 489 listed for branch circuit protection, unlike standard UL 1077 supplementary protectors.

What type of DIN rail is required to mount this breaker?

This miniature circuit breaker mounts on a standard 35mm DIN rail.

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

The NA designation indicates the breaker is designed for the North American market and meets UL 489 standards for branch circuit protection. The SP suffix stands for Single Pack packaging.

What are the alternate part numbers or UPC for the FAZ-D8/1-NA-SP?

The UPC for this breaker is 015081636697. It may also be cross referenced as part number 19YG07.

Is the FAZ-D8/1-NA-SP a current limiting breaker?

Yes, it features a current limiting design that interrupts fault currents within one half cycle, reducing let-through energy that could damage the circuit.

Can power be fed from either direction on this breaker?

Yes, the FAZ-NA series features a reverse feed capable design, allowing power to be fed from either the line or load side.
