Product FAQs
8 answersWhat does the B curve designation mean on the FAZ-B1.5/2-NA?
The B curve indicates that the magnetic trip is calibrated to activate at 3 to 5 times the rated current. This makes it ideal for protecting resistive loads, PLC wiring, and control circuits where low inrush currents are expected.
Is the FAZ-B1.5/2-NA suitable for branch circuit protection?
Yes, the NA suffix indicates this breaker is UL 489 listed for branch circuit protection in North America. It can be used as a primary branch protector, unlike UL 1077 devices which are restricted to supplementary protection.
What type of DIN rail is required to mount this Eaton circuit breaker?
The FAZ-B1.5/2-NA is designed to snap directly onto a standard 35mm DIN rail, which is the industry standard for industrial control panels and automation enclosures.
Are there compatible bus bars for wiring multiple FAZ-NA breakers together?
Yes, Eaton manufactures UL 489 listed bus bar systems, such as the Z-EB series, which are specifically designed to distribute power across multiple FAZ-NA breakers mounted on a DIN rail.
Can this miniature circuit breaker be locked out for maintenance?
Yes, the FAZ-B1.5/2-NA is compatible with Eaton FAZ padlock hasp accessories. This allows electricians to secure the toggle in the OFF position to comply with OSHA lockout/tagout safety procedures.
Do the box lug terminals on the FAZ-B1.5/2-NA require special wire ferrules?
While wire ferrules can be used for stranded wire to prevent fraying, the box lug terminals are designed to securely terminate bare stranded or solid copper conductors ranging from 18 AWG to 6 AWG.
Is the Eaton FAZ-B1.5/2-NA considered a current limiting circuit breaker?
Yes, the FAZ-NA series features a highly efficient current limiting design. Under short circuit conditions, it clears the fault rapidly to minimize the let-through energy, protecting downstream sensitive equipment.
Does this 2-pole breaker feature a common trip mechanism?
Yes, the FAZ-B1.5/2-NA has an internal common trip linkage. If an overload or short circuit occurs on one pole, both poles will trip simultaneously to safely disconnect all ungrounded conductors.
