Description
Part of the FAZ-NA series, this 2-pole miniature circuit breaker is designed for commercial and industrial motor control applications. It delivers reliable thermal-magnetic overcurrent protection for circuits with medium inrush currents. The unit installs onto standard 35mm DIN rail systems and serves as a direct replacement for the legacy WMZT2C25. Rated at 14 kAIC at 480Y/277VAC, it features a current-limiting design, reverse feed capability, and a visual status indicator.Specifications

Product FAQs
10 answersWhat trip curve does the FAZ-C25/2-NA feature, and what applications is it suited for?
This breaker features a C-curve magnetic trip profile, which trips at 5 to 10 times the rated current. It is designed for medium inrush startup currents, making it ideal for small transformers, lighting, pilot devices, and control circuits.
Is the Eaton FAZ-C25/2-NA rated for branch circuit protection?
Yes, the FAZ-NA series is UL 489 listed, meaning it is fully rated for branch circuit device protection in control panels and industrial applications.
Can I use the FAZ-C25/2-NA in DC voltage applications?
Yes, this breaker is dual-rated for both AC and DC applications. It supports up to 96VDC with a 10kA interrupting rating.
What accessories are compatible with the FAZ-C25/2-NA?
It accepts field-installable accessories that mount on the left side of the breaker, including Z-IHK-NA auxiliary contacts, Z-NHK alarm switches, and FAZ-XAA series shunt trips.
What are the recommended tightening torques for the terminals on this breaker?
The required torque depends on the wire size: 21 lb-in for 18-12 AWG, 25 lb-in for 10-8 AWG, and 36 lb-in for 6 AWG conductors.
How does the FAZ-C25/2-NA mount inside a control panel?
It snaps directly onto a standard 35mm DIN rail. No special tools are required for mounting.
Can the FAZ-C25/2-NA be reverse fed?
Yes, this breaker features reverse feed capability, allowing power to be supplied from either the line or load side terminals.
Does the FAZ-C25/2-NA provide visual trip indication?
Yes, it features a color-coded contact position indicator on the front (red for ON, green for OFF) to provide immediate visual status of the circuit.
Is the FAZ-C25/2-NA a current-limiting breaker?
Yes, it utilizes a current-limiting design that interrupts fault currents within one-half cycle, reducing peak let-through energy to protect downstream circuit components.
Can the FAZ-C25/2-NA replace older legacy Cutler-Hammer breakers?
Yes, this FAZ-NA series miniature circuit breaker serves as a direct replacement for the legacy Cutler-Hammer WMZT2C25.
