Product Description
The Penn Union LA-250 is a professional-grade, single-barrel mechanical terminal lug engineered for high-integrity power connections. Precision-machined from high-strength 6061-T6 extruded aluminum alloy, this lug is designed to terminate conductors ranging from 6 AWG up to 250 kcmil (MCM). It is a critical component for terminating main feeders and branch circuits in switchgear, motor control centers, and industrial control panels.
Every LA-250 is finished with premium electro-tin plating to ensure exceptionally low contact resistance and to provide a permanent barrier against atmospheric oxidation and galvanic corrosion. As a dual-rated (AL9CU) connector, it is certified for the safe termination of both copper and aluminum conductors at operating temperatures up to 90°C.

Key Features & Benefits
-
Range-Taking Versatility: A single lug handles a wide wire range from 6 AWG to 250 MCM, reducing the need for multiple lug sizes in your inventory.
-
High-Torque Performance: Specifically designed to withstand a torque of 275 in-lb, ensuring a secure, gas-tight electrical bond that won't loosen under thermal cycling.
-
Solderless Installation: Eliminates the need for specialized crimping tools or soldering; high-pressure termination is achieved with a standard hex wrench.
-
Bimetallic Safety: Engineered to safely connect dissimilar metals, preventing the galvanic corrosion typically associated with aluminum-to-copper transitions.
-
Compact Design: The space-efficient footprint makes it ideal for use in cramped junction boxes and electrical gutters.
