®Amphenol Heavy DutyCylindrical ConnectorsMIL-C-22992, Class LClass L connectors are available only in the specific configurationsprescribed by MIL-C-22992 for either militaryor industrial applications. This rigid configuration controlassures correct interconnection of electrical circuits formaximum safety and reliability. Controlled parametersinclude:Connector shell style and contact type - wall mountand cable connecting receptacles are supplied withsocket contacts only and always lead from the powersource. Plugs (with coupling rings) have pin contacts onlyand always lead to the equipment end.Shell size - the direct relationship of shell size to currentcarrying capability reduces the possibility of inadequatewiring for heavy electrical loads.†Shell SizeCurrent Rating(Amperes)Contact Size28 40 632 60 444 100 1/052 200 4/0Other outstanding design features:Arc quenching design - recessed socket contacts withinthe insert create an arc suppressing chamber which protectsthe user when connectors are separated underload.Programmed coupling sequence - grounding and neutralcontacts engage before power contacts.Waterproof design - a unique combination of grommetsand seals provides waterproofing in any condition -mated or unmated, capped or uncapped.Rugged construction - machined from high strengthaluminum. Straight-line attachment of accessories eliminatespossibility of cable twisting or misalignment.Accessories - supplied with all Class L connectors asindicated on the individual connector descriptions.Replacement accessories may be ordered separately.See pages 12 through 15.Keyway position - four positions of the main keyway areused to discriminate between the following powersources:two wire D.Ctwo wire single phase A.C.three wire single phase A.C.four wire three phase A.C.Insert rotation - when carrying alternating current (A.C),different angular rotations of the insert within the connectorshell are used to distinguish between 60 Hertz and400 Hertz circuits.† MIL-C-22992 includes shell size 48, rated at 150 amperes.
