Hubbell CS6375 50A Flanged Inlet

The Hubbell CS6375 is a 50A flanged locking inlet designed for industrial power connections. It features a steel housing with a zinc-plated finish and a silver flange. The unit supports single-phase 125/250V AC power with a 3-pole, 4-blade configuration. It is built for flush mounting in compatible enclosures.

IP20 and NEMA 12, 4, 4X ratings

The inlet carries an IP20 rating along with NEMA 12, 4, and 4X enclosure ratings for moisture and dust resistance. Its grounded, moisture-resistant and heat-resistant construction suits demanding environments. The flange diameter measures 3.5 inches with a face diameter of 2.172 inches. Standard wiring accepts up to 6 AWG conductors.

Check voltage, phase and mounting before ordering

Verify that your supply matches 125/250V AC single-phase power and that the 50A rating meets your load requirements. Confirm the flush-mount cutout suits the 3.5-inch flange diameter and 2.172-inch face. Ensure your wiring plan accommodates the 4-blade, 3-pole Non-NEMA configuration and maximum 6 AWG wire size.

Questions about this item

How often should the 50 A flanged locking inlet be inspected for heat-resistant contact wear under continuous load?

Inspect the grounded 3-pole inlet annually; the moisture-resistant steel housing and IP20 rating limit internal access, so verify blade tension and torque on the 6 AWG terminals during scheduled shutdowns.

What thermal limit appears first when the 125/250 V AC inlet runs at 50 A all day?

The 3.5 in steel flange dissipates heat, but the IP20 enclosure and NEMA 12/4/4X ratings restrict airflow, so conductor temperature at the 6 AWG terminals becomes the limiting factor.

Does the gray zinc-plated steel inlet generate audible noise or excess heat when energised continuously?

No moving parts mean silent operation; the moisture- and heat-resistant steel housing stays warm but within NEMA 12/4/4X limits, drawing no measurable standby power.
