Product FAQs
9 answersWhat older Eaton or Cutler-Hammer circuit breaker does the FAZ-C0.5/2-NA replace?
This model serves as a direct replacement for the discontinued WMZT2CX0 miniature circuit breaker.
What does the C curve designation mean on this FAZ-NA series breaker?
The C curve indicates a magnetic trip point between 5 and 10 times the rated current. This makes it ideal for medium inrush startup currents, such as those found in small transformers and pilot devices.
Is the FAZ-C0.5/2-NA suitable for branch circuit protection?
Yes, the FAZ-NA series is UL 489 listed, making it suitable for feeder and branch circuit protection in industrial control panels and DIN rail systems.
Is this Eaton 0.5A circuit breaker current limiting?
Yes, it features a current limiting design that provides fast short circuit interruption, reducing the let-through energy that could otherwise damage downstream circuit components.
Does the FAZ-C0.5/2-NA feature a trip-free mechanism?
Yes, it features a trip-free design, meaning the breaker will still trip under fault conditions even if the handle is physically held in the ON position.
How can I verify the contact status of this Eaton miniature circuit breaker?
The breaker includes a color-coded visual status indicator on the front. It displays green when the contacts are open (OFF) and red when the contacts are closed (ON).
Can this 0.5A breaker be used for switching fluorescent lighting loads?
Yes, FAZ-NA series breakers rated 20A and below carry an SWD (switching duty) rating, making them suitable for switching fluorescent lighting loads.
Can power be fed from either direction on the FAZ-C0.5/2-NA?
Yes, this breaker is suitable for reverse feed applications. Power can be supplied to the circuit breaker from either the line or the load side.
What type of terminals does this 2-pole breaker use?
It features box lug terminals with captive screws that cannot be lost during installation. The terminals accept copper wire sizes from 18 AWG to 6 AWG.
