Description
Built for demanding commercial and industrial environments, this three-pole 10A component delivers robust D-curve protection for high-inrush loads. It mounts onto standard DIN rail panels and serves as an exact replacement for the discontinued WMZT3D10 model. Rated for 10kA at 480Y/277VAC, the unit is fully UL 489 listed for branch circuits. Additional benefits include reverse feed capabilities, a trip-free mechanism, and HACR certification for HVAC equipment.Specifications

Product FAQs
8 answersWhat is the trip curve for the FAZ-D10/3-NA breaker?
This breaker features a D-curve tripping characteristic. The magnetic trip point is 10 to 20 times the rated current, making it ideal for high-inrush applications like motors, transformers, and power supplies.
Can the FAZ-D10/3-NA be reverse fed?
Yes, this circuit breaker has reverse feed capabilities. Power can be fed from either the line or the load side terminals.
Can I use the FAZ-D10/3-NA in place of a UL 1077 supplementary protector?
Yes. Because the FAZ-D10/3-NA is a UL 489 listed branch circuit breaker, it can be used in applications that only require UL 1077 supplementary protection. However, a UL 1077 device cannot replace a UL 489 breaker.
Is the Eaton FAZ-D10/3-NA a current-limiting breaker?
Yes, it features a current-limiting design that interrupts fault currents within one-half cycle. This reduces the peak let-through energy to help prevent damage to downstream components.
Does this breaker have a trip-free mechanism?
Yes, the FAZ-D10/3-NA features a trip-free design. The breaker will still trip during an overcurrent or short-circuit fault even if the handle is physically held in the ON position.
How can I verify the contact status of the FAZ-D10/3-NA?
The breaker includes a color-coded indicator on the front face that provides immediate visual confirmation of the device status, showing green for OFF and red for ON.
What older Eaton or Cutler-Hammer model does the FAZ-D10/3-NA replace?
The FAZ-D10/3-NA serves as a direct replacement for the discontinued WMZT3D10 miniature circuit breaker.
Can the FAZ-D10/3-NA be used in DC circuits?
Yes, this breaker is dual-rated for both AC and DC applications. It is rated for up to 96VDC with a 10kA interrupting capacity, making it suitable for industrial control panels requiring DC branch protection.
