Zoro Select 24C398 Compression Lug

The Zoro Select 24C398 is a two-hole copper compression lug built for 300 kcmil stranded copper conductors. It accepts a 3/8 inch stud with a one inch hole centre spacing and carries a 600 V AC rating. The seamless barrel uses die code 66 and a white colour code for crimp identification.

Suited for panel and feeder terminations

Electricians terminating 300 kcmil copper feeders in switchgear or distribution panels will find the long barrel and straight tongue a direct fit. The UL listing supports code-compliant installations at up to 300 degrees Fahrenheit. Installers needing an inspection window or a different stud size should select another connector.

300 kcmil conductor size decides fit

This lug is manufactured for a single conductor size: 300 kcmil stranded copper, both minimum and maximum. Using it with any other wire gauge will not produce a reliable crimp. Verify the conductor size before ordering.

Questions about this item

Will the copper barrel need re-crimping or replacement after years of thermal cycling?

The seamless copper barrel and UL-listed crimp termination are designed for permanent installation; no scheduled re-crimping or barrel replacement is required.

At 600 V AC and 300 °F continuous rating, what limits the lug first during sustained heavy load?

The 300 °F maximum operating temperature is the thermal ceiling; exceeding it degrades the copper-to-wire interface before the 600 V AC voltage rating becomes a factor.

Does the lug generate noticeable heat or require extra cooling when conducting full rated current all day?

The lug itself produces no heat beyond normal I²R loss in the copper; the 300 °F rating covers ambient plus conductor rise without forced cooling.
