| Explanation: |
Brand ULO - Product brand |
Series Code TB44 - 24H/A terminal block series |
Model 24H - Pluggable barrier terminal block at 7mm pitch; this breakdown covers the black seven-pole configuration |
Model Suffix A - Fixed 24H/A configuration |
Positions 07 - 7 poles, arranged on two levels as 4+3 |
Position Unit P - Poles |
Color 3 - Black; illustrated seven-pole configuration |
Product Version 100A - Standard product configuration |
The 24H-A/7.0 is a screw-connected pluggable barrier-terminal family with 7- and 18-pole options. The illustrated 7-pole configuration places four terminals on one level and three on the other, with a staggered layout and a hinged cover.
