Bussmann TB100-14SP Eaton TB100 series panel mount terminal block connector, Breakdown voltage 3600V, 300V, 30A, Double row, barrier, 14-pole, #6-32 TPI Screw, Black, Tin-plated brass terminal, Zinc-plated Steel SEMS philslot screw

Fourteen. The TB100-14SP is a 14-pole double row barrier block, so you get 14 separate circuits with screw terminals on both sides of each barrier for a line and load connection per pole. If you need fewer circuits you can still use it, but the strip is molded as one 14-pole piece and is not meant to be cut down.

The terminals take #6-32 threaded screws, so any #6 ring or spade terminal lands on them directly. The screws supplied are zinc-plated steel SEMS philslot, meaning the captive washer stays with the screw so you are not chasing loose washers inside a panel. Tighten to 9 lb-in.

The block carries a 300V rating, which covers both 120V and 240V control and power circuits. It also lists a 3600V breakdown voltage, which is the dielectric withstand between adjacent poles, not a working voltage. Do not treat the 3600V figure as a service rating.

9 lb-in on the #6-32 screws. That is a small-screw spec, so use an inch-pound driver rather than guessing by feel. Overtightening a #6-32 into tin-plated brass is the usual way these get stripped, and undertightening gives you the loose connection that heats up later.

Its operating range runs -40 to 130 degrees C, so an unconditioned rooftop enclosure in winter and a hot mechanical room in summer are both inside the window. The terminals are tin-plated brass with zinc-plated steel screws, so in wet or corrosive locations the enclosure still has to do the sealing work.

A barrier block like the TB100 series mounts straight to a panel or subplate and separates each pole with a molded barrier, so ring-terminal landings sit isolated from their neighbors without needing rail, end stops, or partition plates. DIN rail terminals make more sense when you expect to add, remove, or reorder circuits over time. A double row barrier block is the simpler choice for a fixed 14-circuit interconnect that gets built once and left alone.

Yes, it is listed as RoHS compliant. That covers restricted-substance requirements on many institutional and export equipment specs. The exact part to reference on a submittal is Bussmann TB100-14SP, in black.
