FAQs
The FWH-150A is designed for 500 V industrial circuits and delivers 150 A protection with a stud mounting configuration. It aligns with Bussmann series high-speed fuses and is suitable for motor drives, switchgear, and control panels where robust overcurrent protection is required. For specific panel compatibility, verify mounting hardware and connector sizes in the product specifications.
The fuse provides fast interruption of overcurrent events, minimizing fault energy and downstream damage in motor drives and power distribution sections. This efficiency reduces downtime, extends component life, and simplifies fault isolation in automated systems, enabling quicker maintenance and less revenue impact due to outages.
Yes, the FWH-150A is RoHS compliant, aligning with modern environmental and regulatory requirements. For additional certifications such as CE or UL, confirm with Eaton’s factory, as those listings may require vendor-specific documentation or qualification testing for your regional compliance requirements.
Ensure the panel cutout and mounting studs match the device’s physical dimensions, with ample space for heat dissipation and easy access for replacement. The FWH-150A uses a stud mounting method, so verify stud size, torque specifications, and terminal clearance in your enclosure design. Proper installation reduces vibration-induced wear and improves serviceability.
ROI benefits come from reduced unplanned downtime, lower maintenance costs, and extended equipment life due to fast fault clearing. Compare expected fault rates, mean time between failures, and the cost of downtime before and after implementation. The FWH-150A’s 150 A/500 V rating and RoHS compliance help optimize protection without over-sizing, contributing to a favorable total cost of ownership.
