Clipsal by Schneider Electric | 56 Series 4 Pin 40A Socket Connector 500V | IP66 Orange
The Clipsal 56CSC440-EO is a 56 Series socket connector rated 40A at 500V AC, wired 3P + E across four round pins. The 56CSC440-EO carries three actives and an earth with no neutral, and is classified socket-outlet type O. It fits the trailing end of a lead rather than a wall, is IP66 rated to AS 60529, and conforms to AS/NZS 3120.
Pin count alone does not establish whether two connectors will mate. Socket-outlet type is the governing classification, and this connector is type O: a distinct pin pattern from other four-pin 56 Series connectors at adjacent current ratings. Confirming type before ordering avoids receiving a socket that physically cannot accept the plug on the existing lead.
The 3P + E configuration supplies three-phase loads drawing no single-phase current through the connector, which covers most direct-connected motors and welding plant. Screw terminals accepting 2.5 to 25mm² and an M40 gland sealing 9 to 29mm cable cover the flexible sizes used on 40A three-phase leads, while IP66 protects the contact chamber from dust and hosed water.
Features
- 40A rated current at 500V — rated operational voltage 500V AC 50Hz conforming to EN 60309-2, for three-phase industrial and commercial supply.
- 3P + E across four pins — three actives and an earth, with no neutral pin in the configuration.
- Socket-outlet type O — the pin pattern classification that determines which plugs will physically mate with this socket.
- IP66 protection — dust tight and protected against powerful water jets, tested to AS 60529.
- Conforms to AS/NZS 3120 — the Australian and New Zealand approval and test specification for cord extension sockets.
- Screw terminals 2.5 to 25mm2 — accepts the conductor range used on 40A three-phase flexible leads.
- M40 cable gland, 9 to 29mm — the gland seals cable outer diameters across that range at the entry point.
- Polycarbonate housing with brass contact sleeves — polycarbonate body over brass sleeves at the contact interface.
- Straight body, external mounting — the connector runs in line with the cable and fits to a lead end, not a wall.
- Operating range -25 to 75 degrees C — covers Australian ambient conditions in exposed and unshaded positions.
- No neutral pin — loads requiring a neutral connection need a five-pin 3P + N + E configuration instead.
Where to use
- 40A three-phase leads — the 56CSC440-EO terminates the socket end where the load draws three-phase only.
- Direct-connected motors and pumps — three-phase plant moved around a site as the work progresses.
- Welding and fabrication equipment — three-phase welders fed through a lead rather than a fixed outlet.
- Construction site distribution — 40A lead sets running from a distribution board out to work areas.
- Rural sheds and workshops — three-phase machinery in unsealed structures exposed to dust and driving rain.
- Temporary and event supply — three-phase installations set up, used, and struck down again.
The 56CSC440-EO carries no neutral pin, so loads requiring a neutral need a five-pin connector instead. It is socket-outlet type O, which will not accept plugs of a different type classification even at the same pin count. It is an external mounting connector for a lead end, not a fixed wall socket outlet, and connector pairing, termination, and testing are the licensed electrician's determination.
