Bussmann TB100-30 – Frequently Asked Questions

1) What are the electrical ratings on the Bussmann TB100-30 terminal block?
The TB100-30 is rated 300V and 30A per pole, with a breakdown voltage of 3600V. That puts it in control-circuit and panel wiring territory, not feeder or branch power distribution.
2) How many circuits can I land on a TB100-30 terminal block?
Thirty. It is a 30-pole double row barrier block, so you get 30 separate terminal pairs across two rows with barriers between poles to keep adjacent connections isolated.
3) What size ring or spade terminals fit the Bussmann TB100-30?
Connections are made with #6-32 threaded screws, so use ring or fork terminals sized for a #6 stud. The screws are zinc-plated steel Phillips/slotted combo heads, and the terminals themselves are tin-plated brass.
4) How does the TB100-30 mount into an enclosure?
It is a screw-mounted panel block, so it fastens flat to the panel or subplate rather than snapping onto DIN rail. If your enclosure is built out with DIN rail only, you will need a rail-mount block or a rail-to-panel adapter plate instead.
5) What torque should I use on the terminal screws?
Tighten the TB100-30 terminal screws to 9 lb-in. Going past that on a #6-32 screw risks stripping the brass; going under it is where you get loose, heating connections on a control panel.
6) Will a Bussmann TB100-30 hold up in an unheated outdoor control cabinet?
Its operating temperature range is -40 to 130 degrees C, which covers unheated outdoor enclosures in cold climates as well as hot equipment rooms. The enclosure still has to handle the moisture and ingress side; the block itself is rated for the temperature swing.
7) Is the barrier style block better than an open terminal strip for a control panel?
A barrier block like the TB100-30 puts an insulating wall between each pole, which is what you want where ring terminals sit side by side at 300V and a strand or a loose lug could bridge to the next circuit. Open strips are faster to wire but rely on spacing alone. With 30 poles in a double row, the barriers are doing real work here.
8) Is the Bussmann TB100-30 CE marked for a panel being shipped to Europe?
Yes, the TB100-30 carries a CE mark. That is the compliance stated for the part; any other approvals for your panel build need to be confirmed against the specific standard your assembly is certified to.
9) What is the exact part number to order this Eaton Bussmann terminal block?
Order it as Bussmann TB100-30, from Eaton's TB100 series. It is the black, 30-pole configuration of that series.
