GEN3 CO3PH520 20A 5 Pin 500V Three Phase Switched Socket Outlet IP66

Description

A three-phase-plus-neutral weatherproof socket and switch in one unit.

The GEN3 CO3PH520 is a 20A, 5-pin three-phase switched socket outlet rated 500V and IP66, combining a three-phase socket and an integral isolating switch in a single weatherproof unit. The five round pins carry three phases, a neutral and earth, and the built-in switch lets the outlet be turned off at the point of use, so three-phase equipment can be isolated without unplugging or switching at the board. At 20A it suits higher-current three-phase equipment than the 10A CO3PH510, and the neutral pin suits loads that also require a neutral connection. Moulded in the Series 56 style from durable PCA18 virgin-grade plastic, it suits outdoor, industrial and wash-down environments where a switched, weatherproof three-phase outlet is needed.

Five Pins: Three Phases Plus Neutral

The CO3PH520's five round pins carry three active phases, a neutral and earth. The neutral pin is what sets the 5-pin socket apart from the 4-pin (three phases plus earth only): it suits three-phase equipment that also needs a neutral connection, such as where single-phase loads are taken from the three-phase supply. The integral switch lets the whole outlet be isolated at the point of use.

Three-Phase Socket and Switch in One

The CO3PH520 brings together a 20A three-phase socket and an isolating switch in a single weatherproof housing. The switch allows the outlet to be turned off locally, providing convenient on-site isolation of connected equipment without needing to unplug or return to the switchboard, a practical safety feature for three-phase tools and machinery in exposed locations.

Built for the Outdoors

Rated IP66, the CO3PH520 is dust-tight and withstands high-pressure water jets. Moulded from PCA18 virgin-grade plastic with 316 stainless steel springs and screws and high-copper brass internals, it is built for long service in exposed and demanding locations, and is covered by Australian/NZ approval or compliance certificates.

Q: What is the difference between a 5-pin and a 4-pin three-phase switched socket?
A: The fifth pin. A 5-pin socket carries three phases plus neutral and earth, while a 4-pin carries three phases plus earth only. The 5-pin suits three-phase equipment that also needs a neutral.

Q: What is the difference between the CO3PH520 and the CO3PH510?
A: The current rating. The CO3PH520 is 20A and the CO3PH510 is 10A. Both are 5-pin three-phase 500V IP66 switched socket outlets.

Q: Is the CO3PH520 suitable for outdoor use?
A: Yes. It is rated IP66, meaning it is dust-tight and protected against high-pressure water jets, suitable for outdoor and wash-down environments.
