FAQs
The FWX-175A uses blade end x blade end connections for quick inline wiring and a stud mounting option for secure panel mounting. Ensure proper torque on studs per Eaton datasheet, verify voltage rating is within system limits, and route conductors to minimize thermal buildup. This simplifies retrofit projects and new installations alike.
FWX-175A is rated 600 V and offers 200 kAIC at AC, with 50 kAIC at 250 Vdc. It can be used on DC circuits rated within 250 V and within its DC interrupt capability. For high-energy DC circuits, confirm the DC interrupt rating and consult the datasheet to ensure safe and compliant operation.
FWX-175A carries UL Recognized and CSA Certified marks, and CE and RoHS compliance. These certifications support supplier qualification, regulatory audits, and safer procurement in regulated industries such as manufacturing, food processing, and energy infrastructure.
With a 200 kAIC AC interrupt rating and 175 A RMS rating, the FWX-175A provides rapid protection against short circuits in motor drives and power panels. This mitigates fault current damage, reduces downtime, and improves overall system reliability in demanding automation environments.
The device measures 3.11 in length and height, 1.23 in in width, and weighs 0.3 lb. It uses blade end x blade end connections and supports stud mounting, making it compatible with standard Bussmann/FWX line configurations and common control panel layouts.
