Description

Delivering reliable branch circuit protection, this single-pole 2A miniature breaker is designed for commercial and industrial applications. It installs into standard DIN rail systems and serves as an exact replacement for the discontinued WMZT1B02 model. Featuring a B-curve thermal-magnetic trip mechanism, the unit responds to overcurrents between three and five times the rated load, making it ideal for PLCs and sensitive control circuits.

Product FAQs

9 answers
What is the trip curve for the FAZ-B2/1-NA-SP circuit breaker?

This miniature circuit breaker features a B-curve thermal-magnetic trip characteristic. It is designed to trip instantaneously at 3 to 5 times the rated current, making it suitable for resistive or slightly inductive loads with low inrush currents.

Is the Eaton FAZ-B2/1-NA-SP rated for branch circuit protection?

Yes, the FAZ-NA series is UL 489 listed for branch circuit protection. It can be used for feeder and branch circuits, unlike UL 1077 supplementary protectors which have more limited applications.

Can I use the FAZ-B2/1-NA-SP in DC control circuits?

Yes, this breaker is dual-rated for both AC and DC applications. While it is rated for 277VAC, it also carries a 10kA interrupting rating at 48VDC for direct current systems.

What type of mounting does the FAZ-B2/1-NA-SP require?

This circuit breaker is designed for 35mm DIN rail mounting. It utilizes a spring clip to easily snap onto standard DIN rail systems used in industrial control panels.

What wire sizes are compatible with the terminals on this breaker?

The box lug screw terminals on the FAZ-B2/1-NA-SP accept wire gauges ranging from 18 AWG to 6 AWG.

Does this breaker have a trip-free mechanism?

Yes, it features a trip-free design. The breaker will trip internally during an overcurrent or short-circuit event even if the handle is physically held in the ON position.

What does the SP suffix mean in the FAZ-B2/1-NA-SP catalog number?

The SP suffix indicates that the breaker is packaged as a single pack for individual sale, distinguishing it from bulk packaging options.

Can the FAZ-B2/1-NA-SP be reverse fed?

Yes, Eaton FAZ-NA series UL 489 miniature circuit breakers are suitable for reverse feed applications, allowing power to be supplied from either the top or bottom terminals.

Is this breaker current limiting?

Yes, the FAZ-NA series features a current-limiting design. It provides fast short-circuit interruption that reduces the let-through energy, helping to prevent damage to downstream circuit components.
