Description
Operating at 480Y/277VAC, this two-pole 30A miniature breaker delivers robust current-limiting performance for commercial environments. The device installs into standard DIN rail systems and industrial control panels without requiring specialized hardware. Equipped with a B-curve trip mechanism, it trips at 3 to 5 times the rated current to protect resistive loads. This UL 489 listed component includes a visual status indicator and features a trip-free mechanism.Specifications

Product FAQs
8 answersWhat does the B-curve trip characteristic mean for the FAZ-B30/2-NA?
The B-curve trip mechanism is designed to trip at 3 to 5 times the rated current. This makes it ideal for applications with low inrush currents, such as resistive loads, control instrumentation, and PLC I/O points.
Is the Eaton FAZ-B30/2-NA suitable for branch circuit protection?
Yes, the FAZ-B30/2-NA is a UL 489 listed miniature circuit breaker, which means it is approved for branch circuit protection in industrial control panels and DIN rail systems.
What wire sizes are compatible with the box lug terminals on this breaker?
The terminals accept 18 to 6 AWG for a single wire connection, or 18 to 10 AWG when connecting two wires.
Does the FAZ-B30/2-NA offer current limiting protection?
Yes, it features a current-limiting design that provides fast short-circuit interruption. This reduces the let-through energy that can potentially damage downstream circuit components during a fault.
Does this breaker require specialized hardware for mounting?
No, the FAZ-B30/2-NA is designed to snap directly onto standard 35mm DIN rail systems without the need for specialized mounting hardware or adapters.
Can the FAZ-B30/2-NA be used in DC control circuits?
Yes, this breaker is rated for use in DC systems up to 96VDC with an interrupting capacity of 10kAIC, making it suitable for various industrial control applications.
What does the -NA suffix indicate in the FAZ-B30/2-NA catalog number?
The -NA suffix designates that this breaker is designed for the North American market and complies with UL 489 standards for branch circuit protection, distinguishing it from IEC-only FAZ models.
What type of trip mechanism does the FAZ-B30/2-NA utilize?
It uses a fixed thermal-magnetic trip unit, providing both long-time delay for overload protection and instantaneous response for short-circuit protection.
