Straight, Round-Pin Connection

The PLS3PH450 is the straight, in-line version of the four-pin 50A plug, sending the cable straight out the back. It's the simple choice where a straight lead exit suits the installation. For tight spots or surface runs where the cable needs to turn away, the angled PLA3PH450 is the alternative.

High-Current Three-Phase, Built Tough

The four round pins carry three-phase power (three actives plus earth) rated to 500V, with a 50A current rating for the largest three-phase equipment in the straight range. To match the heavier conductors a 50A circuit needs, it includes an oversize gland sized for 18–25mm cable. It is IP66 rated, so it is dust-tight and withstands powerful water jets from any direction, with a virgin-grade PCA18 body, 316 stainless steel springs and screws, and brass contacts of greater than 85% copper. A wide -25°C to +70°C operating range and AS/NZS 3123:2005 compliance suit it to demanding Australian industrial sites.

Fast, Interchangeable Termination

The oversize compression gland makes cable termination quick and secure on site, even with larger cable. Because it follows the 56 Series-style format, the PLS3PH450 mates with 50A four-pin three-phase round sockets and inlets and is interchangeable with other major brands. Pair it with a matching 4-pin 50A extension socket to build a complete three-phase extension lead.
