Polaris ISR-250B Insulated Multitap Connector

The Polaris ISR-250B is an insulated multitap connector designed for in-line splicing of aluminum or copper conductors. It accepts stranded copper wire sizes from 6 AWG up to 250 kcmil across two ports. The body is aluminium with a black plastisol finish and insulation material. It is suited for electrical professionals making secure power connections rated up to 600 V.

Practical limits of the 600 V cULus-rated connector

The connector carries a maximum voltage rating of 600 V and a maximum operating temperature of 194 degrees F. It meets cULus and UL 486A standards and is RoHS compliant. The UL 94 flammability rating is not applicable. Hex set screws with a 5/16 in hex size secure each conductor. These specifications define the safe electrical and thermal envelope for the splice.

Check conductor size, port count

Verify that your conductors fall within the 6 AWG to 250 kcmil stranded copper range or the equivalent aluminium range. Confirm that a two-port in-line splice matches the joint you are making. Ensure you have a 5/16 in hex driver for the set screws. The connector length is 4.00 in, so check available space in the enclosure or tray.

Questions about this item

Is this two-port inline splice the right choice when I need to join two cables, or should I look for a version with more ports?

The connector has exactly two ports, so it is designed for a single in-line splice between two conductors. If you need to join three or more wires at one point, a different multitap with additional ports would be required.

How does the 250 kcmil maximum stranded copper size translate when I am terminating cables in the field?

You can use any stranded copper conductor from 6 AWG up to 250 kcmil in each port. The 5/16 inch hex set screws provide the mechanical grip, and the Plastisol insulation covers the connection once the screws are torqued.

What does the 600 V rating actually limit in a 194 °F environment?

The connector is rated for 600 volts maximum in circuits that do not exceed 194 degrees Fahrenheit. It carries cULus listing to UL 486A, and the Plastisol body meets RoHS requirements, but no UL 94 flammability rating applies.
