FAQs
The 7.2WKNHO200 is designed for use with the A3354730 Nickel-plated copper fuse clip. This single-barrel, non-indicating fuse integrates with standard Bussmann series components, ensuring reliable contact and straightforward field replacement in motor protection panels.
It carries a 200 A amperage rating, 7.2 kV voltage rating, and a 40 kAIC interrupt rating. These specifications enable effective motor protection in medium voltage drive systems, ensuring rapid fault isolation and minimizing equipment damage during faults.
Yes. It is specifically designed for motor protection as a back‑up fuse in MV motor starters and drive panels. Its 7.2 kV / 200 A ratings, along with compatible fuse clips, support reliable protection for high‑power motors in manufacturing and process environments.
This product complies with BS 2692-1, a UK/European standard for motor protection fuses. For broader regulatory requirements, verify local CE/UL or other regional standards applicable to your installation and complete any additional certification needs in your project scope.
Since the fuse is non-indicating, plan for external status checks or monitoring in your control scheme. After a fault, replace with a like-for-like unit using the A3354730 clip, and verify proper seating and safety clearances in the motor control panel to prevent future faults.
