The GBC fork-shaped pre-insulated terminal (MPN 18.3930.30) is an open-barrel spade connector for secure, tool-free disconnection on M4 screw terminals. 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 4.3mm screw hole fits M4 fasteners commonly found in terminal blocks, control panels, and electronics enclosures. With a total length of 21.2mm and an external diameter of 6.4mm, the terminal is compact and suitable for wiring in confined spaces. Supplied in packs of 10, colour-coded red for the 0.5–1.5 mm² wire range.

Key Features

• Fork (spade) shape allows connection and disconnection without fully removing the M4 screw
• Pre-insulated red PVC barrel provides electrical insulation immediately after crimping
• Tin-plated copper contact for reliable conductivity and corrosion resistance
• M4 screw hole (Φ4.3mm) fits the most common terminal block and panel screw size
• Rated to 300V maximum voltage

Product Benefits

• Open fork design allows the wire to be swapped or added without fully unscrewing the terminal
• Pre-insulated barrel removes the need for a separate insulating sleeve after crimping
• Red colour coding for 0.5–1.5 mm² speeds cable identification during panel wiring and maintenance
• Compact 21.2mm length fits neatly inside junction boxes and control enclosures
• Pack of 10 provides enough terminals for a full panel row or wiring repair
