Bussmann 125V Time-Delay and Fast-Acting Plug Fuse

Bussmann 125V Time-Delay & Fast-Acting Plug Fuse

The Bussmann Plug Fuse family provides reliable 125V overcurrent protection for circuits that rely on screw-in fuse sockets found in older residential and light commercial fuse panels. This family is available across a range of amperage and fuse-action options, including 1.6A Time-Delay (Fustat), 2A Time-Delay (Fustat), 5A Time-Delay (Fusetron), 5A Fast-Acting, 5.6A Time-Delay (Fustat), and 10A Time-Delay (Fusetron), so electricians and facility maintenance staff can select the exact replacement fuse their panel requires. Every fuse in the family shares a 125V voltage rating and a 10 kiloamp interrupt rating, matching the voltage and interrupt requirements of standard residential and light commercial fuse panels. Plug fuses thread directly into compatible fuse panel sockets, making them a straightforward option for maintaining or restoring circuit protection in older fuse-based electrical systems without rewiring or panel modification. Ordering by the correct amperage and fuse-action type helps ensure the replacement fuse performs as designed within the panel it was installed in.
