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 56K2SW120-GY has K2 in the model number (locks in both ON and OFF positions)

Why it Matters

True Isolation, Key-Controlled Both Ways

Unlike the 15A K2 switch in the same family, the 56K2SW120-GY is rated by Schneider Electric as suitable for isolation duty, so it can be specified where a proper isolator is required for disconnection rather than a switching function alone. The K2 mechanism adds a real operational advantage - the removable 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 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 installations and industrial environments exposed to dust, jetted water and wide temperature swings.

Compliant to Australian Standards

Manufactured to AS/NZS 3133, the 56K2SW120-GY covers M250 motor duty at 250V and is backed by an 18-month Schneider Electric manufacturer warranty. The unit is Green Premium listed and mercury-free.

Q: Is the 56K2SW120-GY rated as an isolator?
A: Yes. Schneider Electric lists this SKU as suitable for isolation duty, so it can be specified where an isolator rated for disconnection is required rather than a switching function only. The 15A K2SW115 sibling is classified as a switch, not an isolator.

Q: What does the K2 in 56K2SW120-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 56K2SW120-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 250V single pole circuits.
