Description
Part of Eaton's FAZ-NA series, this 25A miniature circuit breaker is designed for robust branch circuit protection. It is specifically built to handle resistive and slightly inductive loads in demanding commercial environments. The FAZ-B25/2-NA mounts securely onto standard DIN rails, making it ideal for high-density control panels. It features a common trip linkage and accepts 18-6 AWG wiring. Operating at up to 480Y/277VAC, the breaker offers a B-curve trip profile and HACR rating.Specifications

Product FAQs
8 answersWhat applications are best suited for the B-curve trip characteristic on this breaker?
The B-curve trips at 3 to 5 times the rated current. It is designed for resistive or slightly inductive loads with low inrush currents, such as PLC control wiring, lighting circuits, and business equipment.
Is the FAZ-B25/2-NA approved for branch circuit protection?
Yes. The -NA suffix designates it as a UL 489 listed device, meaning it can be used for primary branch circuit protection in industrial control panels, unlike UL 1077 supplementary protectors.
Does this miniature circuit breaker limit let-through energy during a fault?
Yes, it features a current-limiting design that interrupts fault currents within one half cycle. This reduces peak let-through current and energy, providing superior protection for downstream components.
Can power be reverse fed through the FAZ-B25/2-NA?
Yes, the feed-thru design allows power to be supplied from either the line or the load side terminals without affecting the breaker's protective functions.
How do the box lug terminals accommodate multiple conductors?
The captive box lug terminals can accept a single conductor from 18 to 6 AWG, or two conductors from 18 to 10 AWG, making it easier to wire multiple arrays in control panel assemblies.
How can I quickly verify the contact status of this breaker?
The front of the breaker includes a color-coded indicator that displays red when the contacts are closed (ON) and green when they are open (OFF), allowing for immediate visual verification.
Is this breaker suitable for DC voltage applications?
Yes, in addition to its AC ratings, it is rated for use in DC circuits up to 96VDC with a 10kA interrupting capacity.
What type of DIN rail is required to mount this breaker?
It is designed to snap directly onto a standard 35mm DIN rail, which is the industry standard for industrial control panels and automation equipment.
