Description
Part of the FAZ-NA series, the Eaton FAZ-D5/2-NA is a 2-pole, 5A miniature circuit breaker. It delivers reliable thermal-magnetic protection for commercial and motor control circuits experiencing high inrush currents. This unit installs into standard DIN rail systems and industrial control panels. It serves as a direct replacement for the legacy WMZT2D05 breaker. Rated 10 kAIC at 480Y/277VAC, this UL 489 branch protector utilizes a D-curve trip characteristic and features a trip-free mechanism.Specifications

Product FAQs
7 answersIs the Eaton FAZ-D5/2-NA approved for branch circuit protection?
Yes, the FAZ-NA series is UL 489 listed for branch circuit protection. It can also be applied in circuits where UL 1077 supplementary protectors are allowed.
What types of loads are appropriate for the D-curve trip characteristic?
The D-curve magnetic trip point is 10 to 20 times the rated current. This high threshold prevents nuisance tripping in highly inductive applications, such as motors, transformers, and power supplies.
Can power be reverse fed through this miniature circuit breaker?
Yes, Eaton FAZ-NA breakers are suitable for reverse feed applications. Power can be supplied to either the line or load side terminals.
What size DIN rail is required for installation?
This breaker mounts on a standard 35mm DIN rail. It utilizes a spring clip mechanism that permits removal from an existing busbar system without disassembling the entire array.
What field-installable accessories are compatible with this breaker?
The FAZ-NA series accepts subsequent mounting of auxiliary switches, shunt trips, and busbar connectors to facilitate the wiring of multiple breakers in control panels.
How does the current-limiting design protect downstream equipment?
The breaker interrupts fault currents within one-half cycle of the fault. This rapid response reduces peak let-through current and energy, minimizing potential damage to the circuit.
Does this breaker accept ring terminals?
This model uses standard box lugs. If your application requires ring-tongue connections, you will need to source the equivalent Eaton breaker with an RT suffix, such as FAZ-D5/2-RT.
