The TBU-05-W3-CCS is a terminal block connector designed for high-current electrical applications requiring secure wire termination with clear visibility. It features a 250 V voltage rating, 85 A current rating, and 630 µm (16.00 mm) pitch spacing, with copper alloy tin-plated contacts and an M5 steel zinc-plated screw for reliable connection. The insulator is constructed from PBT rated UL 94V-0 with a polycarbonate clear cover rated UL 94V-2, providing both durability and visual access to internal connections. It accommodates wire sizes from 14 to 6 AWG with a torque specification of 2.5 Nm (25.0 lb·in) and operates reliably across a temperature range of -40°C to +130°C. The device is lead-free and RoHS compliant, making it suitable for industrial control panels, power distribution systems, and equipment requiring high-current switching and termination with visual inspection capabilities.
