  • Product typeElectrical Connectors
  • Insulated for safe connections up to 600 V
  • Accepts stranded copper from 250 to 750 kcmil
  • Three ports simplify multi-wire splicing

Three-Port Aluminium Multitap

The Polaris nsi IPLD750-3B is a black, plastisol-insulated aluminium connector with three ports. It accepts stranded copper or aluminium conductors from 250 kcmil up to 750 kcmil. Each port is tightened with a 3/8 in hex key. The assembly is rated for 600 V and a maximum operating temperature of 194 Degrees F.

Replaces Split-Bolt Or Tape Joints

This multitap replaces traditional split-bolt connectors or hand-taped splices in feeder and branch circuits. The jump is worth it when a single, insulated block reduces installation time and eliminates exposed live parts. cULus listing and UL 486A compliance support code acceptance for 600 V service.

Three Conductors Up To 750 kcmil

The three ports comfortably handle parallel runs of large aluminium or copper feeders within the 250–750 kcmil range. Headroom ends when conductor size exceeds 750 kcmil or when more than three circuits must join in one block. RoHS compliance confirms restricted-substance adherence.
