Powersafe L3 Single Pole Connectors

Phase 3’s Powersafe single pole connectors are the highest rated, safest and finest quality L3 powerlock type plug available. Powersafe are used by the power distribution, events, military and cable assembly industries worldwide. Powersafe Line 3 inline connectors easily terminate to copper cable using either industry standard crimp tools or set-screw contacts. Secure coupling of the three phase plugs and sockets is achieved through an innovative mechanical locking system that disengages with a simple release key.

  • Contact band cannot come out
  • High Impact Insulator (no glass used & flame retardant)
  • Field Installation no special tools required
  • Integral Cable Strain Relief

Ampage & Cable Size Explained

Powersafe Connectors are available in either source or drain format as 800A or 500A. Device ampage is determined by cable size (termination). 300mm2-240mm2 power cable requires 800A plugs, 185mm2 - 25mm2 power cable is supplied with 500A plugs.

Please note, if you require Powersafe for power cable less than Set Screw 120mm2, i.e. 95mm2, 70mm2, 50mm2, 35mm2, 25mm2, you must purchase a reducer kit separately.
