WEG BTB & BTF Terminal Blocks
Universal feed-through and grounding terminals engineered for organized, serviceable panels.
BTB feed-through and BTF grounding blocks anchor every WEG control cabinet. From 2.5 mm² signal circuits to 95 mm² motor feeds, the portfolio combines finger-safe housings, snap-in jumpers, and printable markers so PLC marshalling and field terminations stay intuitive. Gross Automation packages the terminals, jumpers, markers, and distribution hardware your build requires—complete with documentation.
Connection Technologies
Classic rising-cage terminals handle ferruled or bare conductors with high pull-out resistance.
Push-in designs accelerate PLC marshalling and vibration-prone OEM equipment wiring.
High-current aluminum or copper blocks support multiple load taps inside MCCs and cabinets.
Conductor & Current Ratings
0.2–6 mm² (AWG 24–10) feed-through blocks with 24 A continuous ratings.
10–95 mm² (AWG 8–3/0) terminals supporting up to 150 A continuous duty.
Direct-mount BTF blocks rated for the same ampacity as their feed-through counterparts.
Accessory Ecosystem
Plug-in cross and step-down jumpers common terminals without additional hardware.
Clip-on markers, carrier strips, and printer-ready cards maintain labeling standards.
End plates, partition walls, and covers provide segregation and touch-safe operation.
Compliance & Environment
UL 1059, CSA, and IEC 60947 approvals simplify UL508A documentation and CE exports.
-40 °C to +105 °C materials support harsh industrial enclosures.
DIN 35 (Top Hat) and DIN 32 rail mounting with captive screws or spring clips.
Why Panel Builders Choose BTB/BTF Blocks
High-Density Layouts
Single, double, and triple-level terminals conserve rail space while preserving test points and labeling.
Tool-Free Commoning
Plug-in jumpers and distribution combs allow quick reconfiguration without removing conductors.
Service-Friendly Design
Integrated test sockets and hinged marker carriers support troubleshooting without disturbing wiring.
Color-Coded Segregation
Neutral blue, orange safety, and green/yellow ground blocks clarify circuits for maintenance teams.
Terminal Platform Comparison
| Product | Description | Key Specifications | Best For |
|---|---|---|---|
| BTB Single-Level | Standard feed-through blocks for control and low-power circuits. | 0.2–10 mm², 24–41 A ratings, screw or spring clamp options. | PLC I/O marshalling, instrumentation, discrete wiring. |
| BTB Multi-Level | Stacked feed-through terminals with shared jumpers and compact footprints. | Double/triple-level designs, integral test sockets, 500 V insulation. | High-density panels, remote I/O, sensor/actuator cabling. |
| BTF Grounding | Direct-rail grounding blocks with copper alloy feet and PE marking. | 2.5–35 mm², UL Grounding recognized, cross-jumper compatibility. | Equipment grounding, star-point assemblies, shield terminations. |
| Power Distribution | Finger-safe distribution blocks with removable covers and multi-tap outputs. | Up to 760 A, 1x3 / 2x6 configurations, copper or aluminum bodies. | Control power distribution, motor feeds, auxiliary panel circuits. |
