Identifying This SKU - K2

The 56 Series key-operated range uses a naming convention that tells you exactly what the lock does and which key it takes:

• K1 - Locks in OFF position only
• K2 - Locks in ON and OFF positions
• CK - Common Key

This SKU 56K2SW320-GY has K2 in the model number (locks in both ON and OFF positions)

Why it Matters

True Three-Phase Isolation, Key-Controlled Both Ways

The triple-pole design breaks all three active lines in a single operation, giving full three-phase disconnection rather than a switching function on one or two poles. Schneider Electric lists this SKU as suitable for isolation duty, so it can be specified where a proper isolator is required for disconnection. The K2 mechanism means the key locks the circuit either ON for critical loads that must not be casually switched off, or OFF for maintenance and lockout. The rotary handle also accepts two 8 mm padlocks in the OFF position for additional mechanical lock-out, and only authorised keyholders can change the switch state.

Weather-Sealed for Exposed Three-Phase Sites

The IP66 seal keeps dust out and withstands direct water jets. Operating from -25 to 75 °C, the polycarbonate housing is designed to hold up in outdoor three-phase installations - pump sheds, plant rooms, cool room compressors and industrial machinery exposed to dust, jetted water and wide temperature swings.

Compliant to Australian Standards

Manufactured to AS/NZS 3133, the 56K2SW320-GY covers M200 motor duty at 500V and is backed by an 18-month Schneider Electric manufacturer warranty. The unit is Green Premium listed and mercury-free.

Q: Is the 56K2SW320-GY suitable for three-phase circuits?
A: Yes. The triple-pole design breaks all three phases in one action at up to 500 V AC 50 Hz, and Schneider Electric lists this SKU as suitable for isolation duty.

Q: What does the K2 in 56K2SW320-GY mean?
A: The K2 designation means the isolator can be locked with the removable key in either the ON or the OFF position. The K1 variant locks in the OFF position only.

Q: Can the Clipsal 56K2SW320-GY be padlocked for lockout-tagout?
A: Yes. The rotary handle accepts up to 2 padlocks with an 8 mm shackle, giving mechanical lock-out on top of the K2 key mechanism for maintenance and service work on three-phase 500V circuits.
