Polaris ISR-1/0B Insulated Multitap Connector

The Polaris ISR-1/0B is an insulated multitap connector designed for electrical splicing applications. It accommodates stranded copper wire sizes ranging from 14 AWG to 1/0 AWG and supports both aluminum and copper conductor materials. The connector features a black plastisol insulation finish and a body constructed from aluminum. It is rated for a maximum voltage of 600 V and a maximum operating temperature of 194 Degrees F.

Two-Port In-Line Splice with Hex Head

This connector provides two ports for in-line splicing, secured by a hex head requiring a 3/16 in hex size for installation. The plastisol insulation material covers the aluminum body, offering protection for the connection. It meets cULus standards and UL 486A, and is RoHS compliant. The UL 94 flammability rating is listed as not applicable for this specific component.

Verify Wire Gauge and Voltage Requirements

Before ordering, confirm that your application uses stranded copper wire within the 14 AWG to 1/0 AWG range. Ensure the system voltage does not exceed 600 V and that the operating environment stays within the 194 Degrees F temperature limit. Check that a 3/16 in hex tool is available for the hex head installation. This connector is not suited for solid wire or conductor sizes outside the specified range.

Questions about this item

What conductor sizes can the two ports accept?

Each port accepts stranded copper from 14 AWG up to 1/0 AWG and also handles aluminum conductors.

At what temperature should I stop using the connector continuously?

The maximum operating temperature is 194 degrees F, so sustained loads must stay below that limit.

How much heat does the plastisol insulation add during all-day use?

The plastisol finish is rated for 194 degrees F maximum and carries no UL 94 flammability rating.
