Indoor shops and plants that feed 480 V equipment with a neutral need a keyed receptacle that won't accept the wrong plug. The Techspan SCM530R7S is a 30 A pin and sleeve receptacle for 277/480 V three-phase wye systems, in the 4-pole, 5-wire grounding configuration with a 7 o'clock key. Its IP44 splashproof rating suits indoor areas where liquids may splash, not submersion or washdown.
Why plant electricians pick it
- 4-pole, 5-wire layout carries three phases, neutral and ground for equipment that needs 277 V as well as 480 V.
- 7h key and red colour coding keep 480 V plugs apart from lower-voltage devices.
- IP44 splashproof flap cover for indoor commercial and light industrial use.
- Built to IEC 60309 dimensions for interchangeable mating.

Pro tip from the counter
IP44 only means protection from splashing through a flap cover. For outdoor, hose-down or wet-floor locations, step up to the IP67 watertight SCM530R7W, and pair it with an IP67 plug so the seal holds when the two are connected.
Best for: indoor machine shops, commercial kitchens' equipment rooms, maintenance shops, light industrial 480 V equipment with 277 V controls
