Bussmann TB345-16 – Frequently Asked Questions

1) What is the difference between the 600V rating and the 7500V figure on the Bussmann TB345-16 terminal block?
Two different things. The TB345-16 is rated 600V for working/operating voltage, which is the number you design to. The 7500V figure is breakdown voltage, the dielectric withstand point of the barrier insulation between poles. Use 600V when checking it against your circuit; the 7500V tells you how much margin the barriers give you against flashover.
2) What size ring or spade terminals do I need for a TB345 series barrier block?
The TB345-16 uses #10-32 TPI screws, so you want ring or fork terminals sized for a #10 stud. Screws are zinc-plated steel with a Phillips/slot combination head, and the terminals underneath are tin-plated brass.
3) Does the TB345-16 snap onto DIN rail or does it screw down?
It screws down. The TB345-16 is a panel mount block with screw mounting, so it fastens directly to the enclosure backplate or subpanel. If your panel is built around DIN rail, this is the wrong style of block for it, or you'll need a rail-mounted adapter plate to carry it.
4) How tight should I torque the screws on a Bussmann TB345-16 terminal block?
20 lb-in on the #10-32 screws. Going past that on a brass terminal strips threads or cracks the barrier; going under it is where you get hot joints and nuisance voltage drop on a 45A circuit, so use a torque screwdriver rather than feel.
5) Can this terminal block go in an unheated outdoor enclosure or a hot equipment room?
The operating range on the TB345-16 is -40 to 130 degrees C, which covers unconditioned outdoor cabinets in cold climates and hot mechanical or boiler rooms. What it does not cover is the enclosure itself, so wet or dusty locations still need an appropriately rated box around it.
6) What does a double row barrier block give me over a single row strip?
A double row barrier block lands two terminals per pole, one on each side of the center barrier, so an incoming conductor and its outgoing conductor sit on the same pole and are electrically common. That's what you want for a feed-through or distribution point in a control panel. A single row strip only gives you one landing per position, so it's used where you're terminating rather than passing through. The raised barriers between poles are what keep adjacent 600V circuits from arcing across a loose strand.
7) Is the Bussmann TB345-16 CE marked for a panel being shipped to Europe?
Yes, the TB345-16 carries CE marking, so it can be documented in the technical file for a control panel destined for the EU.
