The GBC fork-shaped pre-insulated terminal (MPN 18.3930.40) is an open-barrel spade connector designed for quick connection and disconnection on M5 screw terminals without fully removing the fastener. The red PVC-insulated barrel accepts cable cross-sections of 0.5–1.5 mm² (AWG 22–16) and the tin-plated copper contact ensures reliable electrical conductivity.

The 5.3mm screw hole is sized for M5 fasteners, which are common on larger terminal blocks, bus bars, and power distribution panels. The 8.1mm external diameter and 21.2mm length keep the terminal compact despite the larger screw size. Supplied in packs of 10, colour-coded red for the 0.5–1.5 mm² cable range.

Key Features

• Fork (spade) shape allows cable connection or removal without fully unscrewing the M5 fastener
• Pre-insulated red PVC barrel provides immediate electrical insulation after crimping
• Tin-plated copper contact resists corrosion and maintains conductivity
• M5 screw hole (Φ5.3mm) fits larger terminal blocks, bus bars, and power panel screws
• Rated to 300V maximum voltage

Product Benefits

• Open fork design allows rapid wire substitution — loosen screw, swap fork, retighten
• Pre-insulated barrel combines crimp and insulation in one step, saving wiring time
• Red colour coding identifies 0.5–1.5 mm² circuits instantly during installation and inspection
• Compact 21.2mm length fits inside tight wiring enclosures and terminal panels
• M5 sizing extends the red fork range to larger bus bar and distribution panel connections
