Product FAQs
8 answersIs the FAZ-B10/2-NA rated for branch circuit protection?
Yes, the FAZ-B10/2-NA is UL 489 listed, making it suitable for branch circuit protection. This is a key difference from UL 1077 supplementary protectors. It can be used for internal or external receptacles, motor control circuits, and HACR equipment.
What does the B-curve trip characteristic mean for this breaker?
The B-curve profile means the breaker is designed to trip instantaneously at 3 to 5 times the rated current. This makes it ideal for applications with low inrush currents, such as sensitive control circuits, PLC I/O points, and resistive loads.
Can the FAZ-B10/2-NA be reverse fed?
Yes, this miniature circuit breaker supports reverse feed wiring, allowing for flexible installation in industrial control panels and DIN rail systems.
Is this breaker suitable for switching fluorescent lighting loads?
Yes, the FAZ-B10/2-NA carries an SWD (Switching Duty) rating, meaning it is approved for switching fluorescent lighting loads on a regular basis.
Does this breaker have a trip-free mechanism?
Yes, it features a trip-free design. The breaker will still trip during an overcurrent or short-circuit event even if the handle is physically held in the ON position.
Is the FAZ-B10/2-NA a current-limiting breaker?
Yes, it features a current-limiting design that interrupts fault currents within one half-cycle. This reduces the peak let-through energy, providing superior protection against damage for downstream circuit components.
Can I use this UL 489 breaker in place of a UL 1077 supplementary protector?
Yes, a UL 489 branch circuit breaker like the FAZ-B10/2-NA can generally be used in applications that only require UL 1077 supplementary protection. However, a UL 1077 device cannot be used where UL 489 branch protection is required.
Does this breaker include a visual status indicator?
Yes, the FAZ-NA series features a red and green contact position indicator on the front of the device to clearly show the breaker's operational status.
