Hubbell CS6364C 50A Twist-Lock Connector

The Hubbell CS6364C is a straight blade plug rated for 50 amps at 125/250V AC. It features a 3-pole, 4-wire configuration with screw terminal connections for secure wiring. The housing is made from heat-resistant nylon in black and white. This connector suits industrial and commercial power distribution needs.

Suits installers needing a 50A locking connector

This plug fits applications requiring a 50A, 125/250V AC connection with a cable diameter between .83 and 1.25 inches. It is not for users needing NEMA-standard receptacle compatibility or a connector with an integrated cap or cover. Buyers requiring a higher IP rating than IP20 should look elsewhere. Single-phase operation only.

50A 125/250V AC rating decides fit

The 50 amp, 125/250V AC rating is the primary specification that determines whether this connector matches the circuit requirements. Verify the system voltage and amperage before installation. The 3-pole, 4-wire layout must match the wiring scheme. Cable diameter must fall within the .83 to 1.25 inch range for proper strain relief.

Questions about this item

Should I choose the 50 A version or a lower-amperage plug for my 50 A circuit?

The plug is rated 50 A at 125/250 V AC with three poles and four wires; match it to a 50 A circuit and matching receptacle.

What does the 50 A rating mean when the connector is installed in a real machine?

It means the connector can carry 50 A continuously at 125/250 V AC through its brass screw terminals when wired with cable between .83 in and 1.25 in diameter.

Is this a NEMA locking type and what voltage does that cap in practice?

The connector uses a non-NEMA locking configuration rated for 125/250 V AC single-phase, so the voltage cap in practice is 250 V AC.
