TB010-508-04BE is a 4-pole horizontal terminal block designed for PCB mounting with side interlocking capability. It features a 5.08 mm pitch and supports wire ranges from 26-12 AWG with a rated voltage of 300 V (UL) or 250 V (IEC) and rated current of 20 A per contact. The terminal block is constructed with PA66 housing (UL94V-0 flammability rating), tin-plated copper alloy contacts, and zinc-plated steel screws. Operating over a temperature range of -40°C to 105°C, it offers withstanding voltage of 2000 Vac and surge voltage protection up to 4000 V. This RoHS-compliant component with UL and CE safety approvals is ideal for industrial control systems, power distribution, and general-purpose electrical connections requiring reliable and secure wire termination.
