100 A Pin and Sleeve Plug

The Hubbell M4100P12 is a 100 A pin and sleeve plug rated for 125/250 V single-phase power. It uses a 3-pole, 4-wire configuration with screw-terminal connections and an IP67-rated yellow polybutylene terephthalate housing. The straight-orientation design accepts cable diameters from 1.2 in to 1.78 in and wire sizes from 3 AWG to 1/0 AWG. It is built for grounded IEC-style connections in industrial environments.

Replaces lower-rated or non-watertight plugs

This plug upgrades from devices rated below 100 A or lacking IP67 protection when a fully sealed, high-current connection is required. The jump is worth it for installations exposed to wash-down, dust or temporary immersion where a NEMA 4X enclosure rating is specified. It is not for circuits needing a protective cap or cover, as none is included, nor for multi-phase systems beyond single-phase operation.

Fits industrial power-distribution builds

The screw-terminal wire connection and wide cable-range accommodation simplify field termination on 3 AWG to 1/0 AWG conductors. The IP67 and NEMA 4X ratings free the installer from adding separate weatherproof enclosures at the plug point. The straight orientation keeps cable routing direct in tight panels. Buyers who need an integrated cap, angled entry or a different pole count will need a different model.

Questions about this item

What cable diameter range does the 1.78 in maximum and 1.2 in minimum accept?

The plug fits cables from 1.2 in to 1.78 in outer diameter, matching the 100 A rating and 125/250 V supply.

How do the screw terminals connect, and what step is often missed?

Strip each conductor to the terminal depth, insert into the 3P4W screw terminals, and torque to spec — skipping the torque check is the common error.

When should the polybutylene terephthalate housing or IP67 seal be inspected?

Inspect the yellow housing and seal after any impact, chemical splash, or yearly in wet locations to maintain the IP67 and NEMA 4X ratings.
