Universal Connectivity
Screw clamp, spring clamp, and stud-style terminals support solid, stranded, and ferruled conductors.
Terminal Blocks & Distribution
BTB feed-through, BTF grounding, and power distribution blocks that streamline control wiring.
WEG terminal blocks combine universal connection technologies, multi-level configurations, and intuitive jumper systems to simplify panel wiring. Gross Automation engineers design complete terminal plans, numbering schemes, and accessory lists to keep cabinets organized and serviceable.
Key Differentiators
Space Optimization
Multi-level terminal options double density while maintaining labeling space and test points.
Plug-In Jumpers
Quickly common terminals using push-in jumpers, cross connectors, and distribution blocks.
UL & IEC Compliance
Approvals for up to 600 V and 85 °C ensure compatibility with UL508A and IEC 60204-1 designs.
Terminal System Overview
Feed-Through Blocks
- BTB series screw terminals from 2.5 mm² to 95 mm² conductor capacity.
- Double-level feed-through terminals for compact PLC I/O marshalling.
- Fuse-disconnect terminals for control circuit protection and maintenance isolation.
- Test-disconnect terminals that simplify current measurement points.
Grounding & Distribution
- BTF grounding blocks with direct mounting feet and cross-jumper capability.
- Power distribution blocks rated up to 760 A with finger-safe covers.
- Neutral bars and custom distribution assemblies for multi-circuit panels.
- Insulated splicing blocks for field wiring transitions.
Accessories & Marking
- Plug-in jumpers, step-down jumpers, and partition plates for neat segregation.
- Custom marker cards compatible with standard thermal printers.
- Test plugs, end clamps, and terminal covers for safety and maintenance access.
- Pre-assembled terminal strips labeled to customer standards.
Terminal Families at a Glance
BTB Feed-Through
Screw-clamp terminals in single and multi-level designs for control and power wiring.
- Conductor capacity from 0.2–95 mm² with finger-safe housings.
- Plug-in jumpers support commoning and distribution without tools.
- Available in gray, blue, and orange for neutral and hazardous circuits.
BTI Disconnect & Fuse
Terminal blocks with integrated disconnect levers or fuse holders for control circuits.
- Knife-disconnect or pivoting lever styles rated up to 32 A.
- 5 x 20 mm or 6.3 x 32 mm fuse options for branch protection.
- Test sockets enable meter connections without disturbing wiring.
BTF Grounding & Distribution
Ground blocks and power distribution solutions that maintain clear identification.
- Direct-mount ground terminals with copper alloy feet for low impedance.
- Distribution blocks up to 760 A with snap-on transparent covers.
- Neutral bars and custom assemblies for OEM panel programs.
