Bussmann KTS-R-40 – Frequently Asked Questions
1) Can I use a KTS-R-40 to replace a time-delay fuse like an LPS-RK or FRS-R in a motor circuit?
No, not on a motor load. The KTS-R-40 is a LIMITRON fast-acting, single-element fuse, so it has no intentional time delay and will open on normal motor inrush. Fast-acting R-class fuses belong on non-motor loads such as panelboard feeders, lighting, and resistive circuits. For a motor or transformer, use a dual-element time-delay Class RK1 fuse of the same 40 amp, 600 volt rating.
2) Can I tell by looking whether a KTS-R-40 fuse has blown?
No. The KTS-R-40 is non-indicating, with a melamine glass tube body and no blown-fuse pop-up or window. You have to pull it and check continuity with a meter, or test voltage across the holder. If your maintenance crew wants visual verification without a meter, specify an indicating-style fuse instead.
3) Can I mix a KTS-R-40 with other amp ratings in the same fuse family across my building?
Yes, the KTS-R series runs as a family, so standardizing a facility on KTS-R lets you stock one fast-acting Class RK1 line and change only the amp rating per circuit. The KTS-R-40 is the 40 amp, 600 volt member. Keep all three poles of a given disconnect on the same amp rating and the same series so clearing characteristics match.
