GEN3 SC540 5 Pin 40A 500V Three Phase Fixed Surface Socket Outlet IP66

Description

A high-current three-phase-plus-neutral weatherproof socket.

The GEN3 SC540 is a 5-pin, 40A fixed surface socket outlet with round pins, rated 500V three-phase and IP66, built for outdoor, industrial and wash-down environments. The five round pins carry three phases, a neutral and earth, providing a keyed connection point for three-phase equipment that also requires a neutral, and a standard single-phase flat plug cannot be connected. At 40A, it suits heavy three-phase machinery and plant. As a fixed (non-switched) outlet, it is live whenever its circuit is energised. Moulded in the Series 56 style from durable PCA18 virgin-grade plastic, it stands up to dust, water and demanding sites.

Five Pins: Three Phases Plus Neutral

The SC540'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 round-pin keying keeps these circuits separate so a standard flat-pin plug cannot be connected by mistake.

40A for Heavy Three-Phase Loads

At 40A, the SC540 suits heavy three-phase machinery and plant that draw more than the 32A SC532 or the lower-rated siblings can supply, while sharing the same five-pin configuration and weatherproof build. It is a robust fixed supply point for demanding installations that also need a neutral.

Built for the Outdoors

Rated IP66, the SC540 is dust-tight and withstands high-pressure water jets, and operates across a −25°C to +70°C range. 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 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 SC540 and the rest of the 5-pin range?
A: The current rating. The SC540 is 40A, the SC532 is 32A, the SC520 is 20A and the SC510 is 10A. All are 5-pin round-pin 500V three-phase fixed IP66 sockets.

Q: Is the SC540 switched?
A: No. It is a fixed socket outlet with no switch, so it is live whenever its circuit is energised.
