FAQs
To install the NZMB2-AF80-BT-NA in an existing panel, verify compatible panelboard dimensions and ensure three-phase alignment. Use the front frame clamp terminals for secure terminations and confirm proper alignment with the box terminals. When mounting, keep clearances for cooling and access to the rocker lever accessories. Ensure the device is de-energized during replacement and that wiring follows the plant’s conductor sizing standards and local code requirements.
Key performance specs include an 80 A amperage rating, 440 Vac operating voltage, and a 25 kAIC short-circuit breaking capacity. The trip type is T185, and the unit is a three-pole NZMB2 design with front-frame clamp terminals and a 480-800 A delayed adjustment range. These specs enable selective coordination in distribution feeders and motor circuits while tolerating brief inrush events.
Yes, when configured for 80 A feeders at 440 Vac, this three-pole molded case circuit breaker provides robust protection for distribution panels in harsh or clean environments typical of food processing. Its compact NZM2 frame and front-frame mounting support dense panel layouts, while adjustable magnetic trips aid in tailoring protection to motor drives and conveyors common in this sector.
Compliance details for the NZMB2-AF80-BT-NA are not listed in the data snippet. For regulatory conformity such as CE, UL, and IEC standards and IP ratings, contact Eaton directly or consult the official datasheet and certifications through Eaton customer support to verify current approvals for your region and application.
Warranty is stated as Eaton Selling Policy 25-000, offering one year from installation or eighteen months from shipment, whichever occurs first.
