Two-Hole Compression Lug 250 kcmil

The Zoro Select 24C397 is a copper compression lug designed for terminating 250 kcmil stranded copper conductors. It features a two-hole tongue with a 3/8 inch stud size and one inch hole centre spacing for secure mounting. The seamless barrel construction and yellow colour code identify it for use with die code 62 crimping tools. This component is rated for 600 volts AC and a maximum operating temperature of 300 degrees Fahrenheit.

Seamless Barrel Crimp Connection

The seamless barrel eliminates a potential failure point at the seam during high-current crimping. A straight tongue angle and 1.13 inch tongue width allow direct bolting to busbars or equipment terminals without adapters. The crimp termination style requires a compatible compression tool matched to die code 62 to achieve a reliable gas-tight joint. No inspection hole is present, so visual verification of wire insertion must occur before crimping.

For 250 kcmil Copper Terminations

This lug suits installers terminating a single run of 250 kcmil stranded copper wire where a two-hole mounting pattern is specified. It is not intended for aluminium conductors, smaller wire gauges, or applications requiring an inspection window for post-crimp verification. Buyers needing a different stud size, hole spacing, or barrel length should select an alternative connector.

Questions about this item

Will the 250 kcmil copper barrel reach its 300 °F temperature limit before the crimp fails under continuous load?

The lug is rated for a maximum operating temperature of 300 °F; sustained current that keeps the copper at or below this temperature will not degrade the crimp connection.

How much heat does the seamless copper barrel generate when carrying full rated current all day?

Heat rise depends on the actual current and ambient conditions; the connector itself has no internal resistance specification, so temperature must be verified in the installed circuit.

Which crimp die code matches the yellow colour code on this 250 kcmil lug?

The lug carries die code 62 and a yellow colour code, so a 62-series compression die is required for a proper crimp.
