Product FAQs
9 answersWhat does the B-curve trip characteristic mean on the FAZ-B15/1-NA-SP?
The B-curve indicates a magnetic trip point of 3 to 5 times the rated current. It is designed for applications where low levels of inrush current are expected, such as resistive loads, lighting, or sensitive control circuits.
Is the FAZ-B15/1-NA-SP rated for branch circuit protection?
Yes, the NA designation in the catalog number indicates it is a UL 489 listed miniature circuit breaker. This makes it suitable for primary branch circuit protection in industrial control panels, rather than just supplementary protection.
Can the FAZ-B15/1-NA-SP be used in DC control circuits?
Yes, this breaker is dual-rated for both AC and DC applications. It supports up to 277VAC and 48VDC, providing a 10kA interrupting rating for both voltage types.
Does this breaker support reverse feeding?
Yes, the FAZ-B15/1-NA-SP is suitable for reverse feed applications. Power can be supplied to either the line or load side terminals without affecting the protective functions of the breaker.
How does the trip-free design improve safety on the FAZ-B15/1-NA-SP?
The trip-free mechanism ensures that the breaker will still trip and interrupt the circuit during an overcurrent or short-circuit fault, even if the operating handle is physically held in the ON position.
Does the breaker provide a visual status indicator?
Yes, it features a color-coded indicator on the front face. Green indicates the contacts are open and the breaker is OFF, while red indicates the contacts are closed and the breaker is ON.
What does the SP suffix indicate in the FAZ-B15/1-NA-SP catalog number?
The SP suffix stands for single pack, meaning the breaker is packaged and sold individually rather than in bulk OEM quantities.
How is the FAZ-B15/1-NA-SP secured inside a control panel?
This miniature circuit breaker mounts directly onto a standard 35mm DIN rail. It utilizes a spring clip mechanism for quick installation and removal without specialized tools.
What wire sizes are accepted by the terminals on this breaker?
The box lug terminals on the FAZ-B15/1-NA-SP are designed to accept wire gauges ranging from 18 AWG to 6 AWG.
