Bussmann S501-500-R – Frequently Asked Questions

1) Is the Bussmann S501-500-R a fast-acting fuse or a time-delay fuse?
Fast-acting. The S501-500-R opens quickly under fault current rather than riding through a temporary inrush, so it suits circuits feeding sensitive conductors and equipment. If you are protecting a motor or transformer that draws a heavy starting surge, a fast-acting element is the wrong choice and a time-delay fuse is what you want in that position.
2) What does high-breaking capacity mean on the Bussmann S501-500-R, and when do I need it?
High-breaking capacity means the fuse is built to safely interrupt elevated fault currents without losing its protective function. That matters where the available short-circuit current at the point of installation is high, such as service entrance and distribution gear, because a low interrupting rating device in that position can fail to clear the fault. The S501-500-R is specified for exactly those higher fault current circuits.
3) I need to order the exact Bussmann S501 fuse my panel schedule calls out. What part number do I ask for?
Order it as S501-500-R. That is the manufacturer part number, and it is the single model offered under this Bussmann S501 fast-acting, high-breaking capacity fuse. There are no finish, size, or voltage sub-options to pick, so the catalog number alone fully identifies the part for a purchase order or a drawing callout.
4) Can I use the Bussmann S501-500-R as a direct replacement for a blown fuse in existing switchgear?
Yes, the S501-500-R is intended both for new installations and as a direct replacement, and it is used in panelboard and switchgear circuit protection as well as industrial power distribution. Pull the old fuse and match the catalog number printed on its body; a fast-acting high-breaking capacity fuse must be replaced with the same type and rating, not a substitute class.
5) Is the Bussmann S501-500-R suitable for an industrial plant feeder, or is it a control panel fuse?
Both ends of that range are covered. The S501-500-R is applied in industrial power distribution systems, panelboard and switchgear protection, motor and equipment protection, and general commercial and industrial electrical installations. It is a professional circuit protection fuse rather than a residential cartridge fuse.
