GEN3 SC420 4 Pin 20A 500V Three Phase Fixed Surface Socket Outlet IP66

Description

A three-phase round-pin weatherproof socket for industrial use.

The GEN3 SC420 is a 4-pin, 20A fixed surface socket outlet with round pins, rated 500V three-phase and IP66, built for outdoor, industrial and wash-down environments. The four round pins carry three phases plus earth, providing a keyed three-phase connection point for industrial equipment, and a standard single-phase flat plug cannot be connected. At 20A, it serves higher-current three-phase supply points than the 10A SC410. 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.

Three-Phase Connection

The SC420's four round pins carry three active phases plus earth, making it a fixed connection point for three-phase equipment rated up to 500V. The round-pin keying keeps three-phase circuits separate from single-phase ones, so a standard flat-pin plug cannot be connected by mistake, an important safeguard where both supply types are present on site.

20A for Larger Three-Phase Loads

The 20A rating suits three-phase equipment drawing more than the 10A SC410 can supply, while sharing the same round-pin keying and weatherproof build. It is a practical fixed supply point for larger industrial machinery and equipment.

Built for the Outdoors

Rated IP66, the SC420 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: Is the GEN3 SC420 single-phase or three-phase?
A: Three-phase. It is a 4-pin, 500V socket with four round pins carrying three phases plus earth, for three-phase equipment.

Q: What is the difference between the SC420 and the SC410?
A: The current rating. The SC420 is 20A and the SC410 is 10A. Both are 4-pin round-pin 500V three-phase fixed IP66 sockets.

Q: Is the SC420 switched?
A: No. It is a fixed socket outlet with no switch, so it is live whenever its circuit is energised.
