Bussmann 4164-FR – Frequently Asked Questions

1) What fuses does the Bussmann 4164-FR limiter block accept?
The 4164-FR is built for ANN and ANL fuses, bolt-down limiter style with stud terminals. It is a single-pole block covering the 10 to 800 amp range of those fuse sizes, so it will not take a cartridge or Class J/T fuse with ferrule or knife-blade ends.
2) What torque do the studs on the Bussmann 4164-FR get tightened to?
12 lb-in on the stud connections. That is inch-pounds, not foot-pounds, so use a small torque screwdriver or an inch-pound wrench. The block ships with free running nuts, and holding that torque is what keeps the fuse seated and the termination vibration-resistant in a panel or MCC.
3) Does the Bussmann 4164-FR come with the mounting nuts, or do I order those separately?
Free running nuts are included with the block. The fuse itself is not: ANN or ANL fuses are ordered separately in the amp rating your circuit calls for, anywhere in the 10 to 800 amp range the block covers.
4) Will a blown fuse show on the Bussmann 4164-FR block?
No, it is a non-indicating block, so there is no pop-up pin or LED to flag an open fuse. Troubleshooting means metering across the studs or pulling the fuse. If your panel needs at-a-glance status, plan on an external blown-fuse indicator or monitoring relay in the design.
5) Is the base on the Bussmann limiter block plastic or something tougher?
Molded alkyd, a thermoset used for its dielectric strength and dimensional stability under continuous heat. It holds shape better than a common thermoplastic on a high-amp block that runs warm, which is why it shows up in switchgear and motor control applications.
