Why it Matters

Two functions in one enclosure
Reversing and changeover in a single 4 pole unit means one enclosure handles motor direction reversal or supply source selection. Fewer enclosures on the wall, fewer terminations, and clear rotary positions make operator intent unambiguous when the switch is checked from across the plant floor or a distribution yard. That translates to faster installation, tidier switchboard layouts, and reduced maintenance overhead across the life of the installation.

Australian weatherproof pedigree
The 56 Series is the workhorse of Australian industrial and outdoor switchgear. IP66 sealing and the polycarbonate housing shrug off dust ingress, driving rain, and hose-down cleaning, which suits caravan parks, farm sheds, marine berths, food processing plants, and construction site distribution boards. Operating temperature spans -25 to 75 °C, covering climate extremes from alpine winters to tropical summers without compromising rated performance.

Three-phase capable, 20A per phase
The 500V AC rating and 4 pole configuration cover three-phase and neutral or three-phase plus earth switching, giving contractors a single switch for irrigation pumps, conveyors, hoists, and portable equipment rated up to 20A per phase. The 1.7 kA making capacity and 20 kA breaking capacity provide the fault-clearing headroom required for AS/NZS 3000 compliant installations.

Q: Can this switch reverse a three-phase motor?
Yes. The reversing function swaps two of the three phases through the rotary action, changing motor rotation direction. It is intended for occasional direction changes rather than frequent inching or plugging duty.

Q: What does changeover mean on this switch?
Changeover lets you select between two 4 pole supplies feeding a single load, such as switching a distribution board between mains power and a backup generator. Only one supply is connected at a time, preventing paralleling of sources.

Q: Is 56SW420CO-GY safe for outdoor installation?
Yes. The IP66 rating means it is dust-tight and protected against powerful water jets, so external walls, unroofed switchboards, and washdown zones are all suitable locations when installed to AS/NZS 3000.
