Thomas & Betts 3KG43 Fork Terminal

Description:

The Thomas & Betts STA-KON 3KG43 Fork Terminal (RB14-8F) is used to provide a secure crimped wire termination for 18–14 AWG conductors on #8 stud connections. Commonly installed in industrial control panels, motor control centers, PLC cabinets, automation systems, HVAC equipment, and electrical distribution panels, this nylon-insulated copper fork terminal features a brazed-seam barrel for high pull-out strength and dependable electrical conductivity. Maintenance teams and system integrators use this terminal for repair, retrofit, expansion, and replacement of low-voltage electrical wiring connections.

Applications:

The Thomas & Betts STA-KON 3KG43 is designed to terminate 18–14 AWG stranded or solid copper conductors to #8 screw terminals without completely removing the terminal screw during servicing. Its fork-style tongue enables fast installation and maintenance, making it ideal for switchgear, relay panels, control cabinets, OEM machinery, industrial automation equipment, commercial electrical systems, and power distribution assemblies.
