Bussmann BK/GMT-DUMMY – Frequently Asked Questions

1) What does a Bussmann BK/GMT-DUMMY dummy fuse actually do in a telecom fuse panel?
The BK/GMT-DUMMY is a GMT-style placeholder, not a current-limiting fuse. It fills an unused fuse position in telecommunications DC power circuit protection panels so the clip position stays occupied and correctly spaced during stocking and routine servicing. Use a live GMT fuse where you actually need overcurrent protection on the circuit.
2) Will the BK/GMT-DUMMY fit standard GMT fuse clips?
It is built to the common GMT fuse footprint and clip spacing, with a molded thermoplastic body measuring .78 x .61 x .12 inches. The tin-plated beryllium copper terminals give it the spring contact and corrosion resistance to sit in the clips long term without loosening.
3) Is the BK/GMT-DUMMY an alarm-indicating GMT or a plain one?
Non-indicating. There is no pop-out indicator flag or alarm pin on it, so it will not trip a panel's blown-fuse alarm circuit. If your frame uses alarm-indicating GMT positions wired to a monitoring bus, a non-indicating placeholder is what you want in the spare slots, not in an alarm-monitored protected position.
4) Can I use a GMT dummy fuse instead of just leaving the fuse slot empty?
That is the point of it. An empty GMT position leaves the clips exposed and unspaced in the panel; the BK/GMT-DUMMY holds the position with a thermoplastic body and plated terminals so rack and frame positions stay consistent for maintenance and future circuit turn-up. It carries no fuse element, so it provides no circuit protection.
5) What is the exact part number to order for the Bussmann GMT dummy fuse?
Order Bussmann BK/GMT-DUMMY. That is the manufacturer part number, supplied in standard packaging, and it is a single non-indicating fast-acting-style dummy configuration with no amperage or finish options to specify.
6) Is the BK/GMT-DUMMY body going to hold up in a hot central office frame?
The body is molded thermoplastic and the terminals are tin-plated beryllium copper, chosen for spring retention in the clips and corrosion resistance over long service in DC power distribution panels. Each piece weighs about .1 lb.
