Why it Matters

The Clipsal 56 Series is the go-to industrial switchgear range for Australian trades. The 20A variant steps up from the base 10A model to handle heavier motor loads and larger three-phase circuits, while keeping the same rugged polycarbonate enclosure that shrugs off dust, driving rain and washdown environments.

Higher Current for Larger Loads

Where the 10A version suits smaller motors and control circuits, the 20A rating opens up bigger jobs — compressors, pumps, workshop machinery. The 20 kA breaking capacity gives significant fault-clearing headroom, and the 1.2 kA one-second short-time withstand rating means the switch holds up under short-circuit conditions before upstream protection trips.

M150 Motor Duty to AS/NZS 3133

Rated M150 at 500V under AS/NZS 3133, this switch is classified for direct switching of three-phase motor loads at that duty level. The 4 kV rated impulse withstand voltage covers transient overvoltage typical of Australian industrial supply networks. The rotary handle also accepts up to two padlocks with 8–8 mm shackles for lockout-tagout during motor maintenance.

Built for the 56 Series System

The switch slots into the wider Clipsal 56 Series family of enclosures, adaptors and mounting accessories, so it drops into existing setups without redesign. Fixing is by screws with a 0.8 N·m tightening torque, and the surface-mount format installs directly on walls, steel frames or purpose-built mounting blocks.

Q: What is the current rating of the Clipsal 56SW320-GY?
A: It is rated 20A at 500V AC 50Hz, twice the current capacity of the 10A 56SW310 model.

Q: What motor size does the 56SW320-GY switch?
A: It is rated M150 at 500V under AS/NZS 3133, suitable for direct switching of three-phase motor loads to that classification.

Q: What is the IP rating of this switch?
A: It is IP66, offering complete dust protection and resistance to powerful water jets, so it is suitable for outdoor and washdown installations.
