350 terminal blocks provide screw wire termination with a protective stainless-steel spring and one row of PCB pins. Choose the 3.5mm or 3.96mm pitch and the standard or R body orientation. Available assemblies have 2–24 poles.
| Model | Pitch | Configuration | UL use-group B rating |
|---|---|---|---|
| TB11-350/3.5 | 3.5mm | Standard orientation | 10A, 300V |
| TB11-350R/3.5 | R orientation | ||
| TB17-350/3.96 | 3.96mm | Standard orientation | 7A, 300V |
| TB17-350R/3.96 | R orientation |
Use the individual outline to position the wire entry, screw access and PCB pins. The R orientation has a different pin-exit direction relative to the body.
All four models are rated 10A, 130V under IEC overvoltage category III and pollution degree 2. Rated impulse voltage differs by model.
| Model | Overvoltage category | Pollution degree | Rated voltage | Rated impulse voltage |
|---|---|---|---|---|
| TB11-350/3.5 | III | 2 | 130V | 2.5kV |
| TB11-350R/3.5 | 1.25kV | |||
| TB17-350/3.96 | ||||
| TB17-350R/3.96 |
Ratings for IEC category III/pollution degree 3 and category II/pollution degree 2 are unspecified. The general UL rating is 10A, 300V without a stated use group. Use-group B ratings are listed separately in the selection table; TB17 models specify 7A for that group. Use groups C and D and certificate file numbers are unspecified.
