Product FAQs
6 answersWhat type of trip curve does the FAZ-D4/1-NA-SP feature?
This miniature circuit breaker utilizes a D-curve thermal-magnetic trip profile. It is designed to handle high inrush currents, typically 10 to 20 times the rated current, making it ideal for motors, transformers, and highly inductive loads.
Can the FAZ-D4/1-NA-SP replace older Cutler-Hammer models?
Yes, this unit serves as a direct replacement for the discontinued Eaton and Cutler-Hammer WMZT1D04 miniature circuit breaker.
Is the Eaton FAZ-D4/1-NA-SP rated for branch circuit protection?
Yes, this breaker is UL 489 listed. This certification means it is approved for primary branch circuit protection in industrial control panels, unlike UL 1077 devices which are only rated for supplementary protection.
Does this breaker feature a trip-free safety mechanism?
Yes, it includes a trip-free design. This ensures the breaker will still trip and interrupt the circuit during an overcurrent or short-circuit event, even if the toggle handle is physically held in the ON position.
What type of mounting rail is required for installation?
This breaker snaps directly onto standard 35mm DIN rail systems, which are commonly used in industrial control panels and automation enclosures.
Does the FAZ-D4/1-NA-SP have a contact position indicator?
Yes, it features a visual red and green status indicator on the front of the device, allowing operators to quickly verify if the internal contacts are open or closed.
