Screw Type Terminal Board

Application

Terminal boards are a fundamental component wherever multiple conductors must be safely joined or distributed:

• Industrial control panels — organising PLC, relay, and sensor wiring in machine control cabinets
• Power distribution boards — branching mains supply to individual circuit breakers or loads
• Building automation systems — HVAC, lighting control, and access control wiring hubs
• Railway rolling stock — cab wiring, door control, and traction control panels requiring vibration-resistant connections
• Renewable energy systems — solar inverter and wind turbine junction boxes
• Marine and offshore panels — navigation, propulsion control, and alarm system wiring
• Telecommunications equipment — structured cabling cross-connect and patch panels

Advantage

• Tool-free or one-tool termination — spring-clamp variants accept conductors with a simple push; screw types tighten with a standard flat-blade screwdriver, minimising installation time
• Full visual inspection — transparent or open-frame designs let engineers verify wire insertion depth and confirm no stray strands without removing covers
• Colour-coded housings — grey for signal, blue for neutral, green/yellow for earth, and orange for hazardous-voltage circuits follow IEC 60445 conventions out of the box
• Modular and expandable — boards can be assembled from individual blocks to the exact pole count required, and extended later without rewiring existing positions
• High vibration resistance — tin-plated copper contacts with 0.5 N·m minimum clamp torque maintain contact integrity under IEC 60068-2-6 vibration profiles
• UL94 V-0 housing — self-extinguishing polyamide prevents flame propagation inside control enclosures, meeting fire-safety requirements worldwide
