Description
Rated for 14kAIC at 277VAC, this 1-pole 20A miniature circuit breaker ensures excellent fault interruption for commercial and industrial facilities. It snaps onto standard DIN rails and replaces older WMZT1C20 units in existing control panels. The Eaton FAZ-C20/1-NA-SP utilizes a C-curve thermal-magnetic trip mechanism to handle medium inrush startup currents. This HACR and SWD rated breaker also features a trip-free design and current-limiting performance for enhanced safety.Specifications

Product FAQs
8 answersWhat is the trip curve for the FAZ-C20/1-NA-SP circuit breaker?
This breaker features a Type C trip curve, which is designed to trip between 5 and 10 times the rated current. It is ideal for medium inrush startup currents found in small transformers, pilot devices, and control circuits.
Is the FAZ-C20/1-NA-SP rated for branch circuit protection?
Yes, the NA designation indicates this device is UL 489 listed for branch circuit protection in North America, unlike standard UL 1077 supplementary protectors.
What does the SP stand for in the FAZ-C20/1-NA-SP catalog number?
The SP suffix stands for single packaging. The breaker itself shares the exact same technical specifications as the standard FAZ-C20/1-NA model.
Can power be fed from either direction on this miniature circuit breaker?
Yes, this breaker allows for reverse feeding. Power can be safely fed from either the line or load side terminals.
How many wires can be connected to the box lugs on this 20A FAZ breaker?
The box lug terminals are designed to accept either a single conductor between 18 AWG and 6 AWG, or two conductors ranging from 18 AWG to 10 AWG.
Is the Eaton FAZ-C20/1-NA-SP considered a current-limiting device?
Yes, it features a current-limiting design that interrupts short-circuit faults within one half cycle. This reduces peak let-through energy and minimizes potential damage to the electrical system.
Does this circuit breaker have a trip-free mechanism?
Yes, the internal trip-free design ensures the breaker will still trip during an overcurrent event even if the handle is physically held in the ON position.
Does the FAZ series provide visual status indication?
Yes, the front of the breaker features a color-coded indicator that displays red for ON and green for OFF, allowing for immediate visual status verification.
