Bussmann KU6-WWCMT Eaton KU series panel mount terminal block connector, Top cover and two end plates, 600V, 60A, Six-pole, Black, Molded nuclear grade noryl base, nickel-plated brass washer head - KU6-WWCMT

The KU6-WWCMT is a 600V, 60A six-pole panel mount terminal block connector. That covers standard 480Y/277V and 600V control and power circuits up to 60 amps per pole. Above 60A per pole you need a heavier block.

Tighten to 20 lb-in. The terminals use a nickel-plated brass washer head screw, so use a calibrated torque screwdriver rather than guessing: under-torque on a 60A connection is what causes hot joints, and over-torque strips the brass.

No. Despite being grouped with panelboards, the KU6-WWCMT is a six-pole panel mount terminal block connector, a wire-to-wire junction point inside an enclosure. It has no breakers and no bus for branch circuits. For a distribution panelboard, look at something like the ABB ReliaGear Pro-Stock 42-circuit panelboard or the ABB MeterMod III 400A three-phase main lug panelboard.

No. The KU6-WWCMT is a 60A, 600V six-pole terminal block connector with 0.625 in center spacing and a 20 lb-in terminal torque - its current rating is far below a 400A service. For a 400A three-phase main lug distribution point, the ABB MeterMod III 400A three-phase main lug panelboard is the class of product that matches that duty. The KU6-WWCMT is appropriate for control, instrumentation, and branch conductor terminations at or under 60A.

A top cover and two end plates ship with the KU6-WWCMT, so the block arrives with its live parts shielded and both ends closed out. Nothing additional is needed to cover the assembly.

It is rated to 105 degrees C operating temperature, and the base is molded nuclear grade noryl, so it holds up in warm control cabinets and enclosures where standard thermoplastic blocks soften.

The KU6-WWCMT uses a molded nuclear grade noryl base and a nickel-plated brass washer head, is rated to a 105 degrees C operating temperature, and is RoHS compliant. That thermal rating and material spec are why it gets specified in equipment and control enclosures rather than a general distribution assembly such as the ABB MeterMod III 400A three-phase main lug panelboard, which is built as a service-entrance style board. Confirm any nuclear qualification paperwork with the manufacturer for your specific application.

Yes, the KU6-WWCMT is RoHS compliant. For any other listing or agency approval on this part, check with Bussmann directly.

Order Bussmann KU6-WWCMT. The KU6 designates the six-pole KU series body and the WWCMT suffix is the version supplied with the washer head screws, top cover and two end plates in black.
