FAQs
For reliable installation, ensure a clean, unused stud connection with appropriate torque per manufacturer guidelines and use a compatible lug or terminal. Verify correct amperage rating (175 A) and maintain adequate clearance around the fuse to prevent heat buildup. Use a non-indicating fuse indicator to simplify panel diagnostics while keeping RoHS-compliant components in series with the load.
The FWH-175A is rated at 175 A with a voltage rating of 1000 Vac and 800 Vdc. It features a stud mounting method and a standard packaging type, with RoHS compliance. The non-indicating design means status must be inferred from system current, fault indicators, or upstream protection devices.
Yes, the FWH-175A is designed for fast fault clearing in high-power environments such as motor drives and heavy-duty controls. Its 1000 Vac / 800 Vdc rating supports high-voltage circuits, and the 175 A capacity provides robust protection against short circuits while minimizing downtime and equipment damage.
The data indicates RoHS compliance. For additional certifications like CE or UL, consult Eaton or the local distributor to confirm regional approvals and scope of certification. Always validate your specific regulatory requirements before deployment in a new market or on customer-critical equipment.
The fast-acting protection reduces energy and fault propagation, which lowers repair costs and unplanned downtime. Its compatible form factor and robust mounting simplify installation and maintenance planning, improving panel density and uptime. In sum, the FWH-175A contributes to longer motor life, fewer nuisance trips, and a quicker return on investment in demanding industrial environments.
