Bussmann SC-7 – Frequently Asked Questions
1) Is the SC-7 a time-delay fuse or fast-acting?
Time-delay. The SC-7 holds for 12 seconds at 200 percent of its 7 amp rating, so it rides through motor inrush and transformer magnetizing current instead of opening on a normal startup surge. If you need a fast-acting fuse for protecting solid-state electronics, this is the wrong characteristic.
2) What is the interrupting rating on the SC-7, and is it enough for my available fault current?
The SC-7 is listed at 10 kAIC at 170 Vdc, and it is a current-limiting fuse, meaning it reduces the peak let-through energy during a short circuit rather than just opening. Compare the 10 kAIC DC figure against the available fault current at your panel before you rely on it for DC service protection.
3) Does the SC-7 have a blown-fuse indicator?
No. It is a non-indicating fuse, so there is no pop-up pin or window to show it has opened. If you are maintaining a panelboard and want visual fault identification without pulling fuses, you will need an indicating type or a separate fuse-blown indicating light in the panel.
4) Where are Bussmann SC series Class G fuses typically used in a building?
Fusible branch panelboards and branch circuit protection, which is why a property manager or electrical contractor usually meets them in lighting panels, control circuits, and small motor or transformer branches. The rejection-style body keeps the panel standardized, so a 7 amp circuit stays a 7 amp circuit through future service work.
