Description

Screw terminals with wire-protection springs

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.

ModelPitchConfigurationUL use-group B rating
TB11-350/3.53.5mmStandard orientation10A, 300V
TB11-350R/3.5R orientation
TB17-350/3.963.96mmStandard orientation7A, 300V
TB17-350R/3.96R 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.

Electrical ratings

All four models are rated 10A, 130V under IEC overvoltage category III and pollution degree 2. Rated impulse voltage differs by model.

ModelOvervoltage categoryPollution degreeRated voltageRated impulse voltage
TB11-350/3.5III2130V2.5kV
TB11-350R/3.51.25kV
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.
