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 56K2SW332-GY has K2 in the model number (locks in both ON and OFF positions)

Why it Matters

Top-of-Range Three-Phase Isolation, Key-Controlled Both Ways

At 32A with a 32 kA breaking capacity, the 56K2SW332-GY sits at the top of the 56 Series triple-pole key-operated range. The triple-pole design breaks all three active lines in a single operation, and Schneider Electric lists this SKU as suitable for isolation duty. 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 Heavy-Current 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 56K2SW332-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: What sits behind the 32 kA breaking capacity rating?
A: Breaking capacity is the largest prospective fault current the switch can safely interrupt. At 32 kA across three phases, the 56K2SW332-GY is rated to safely open under fault currents up to that level, giving good headroom on heavier 500V three-phase circuits.

Q: What does the K2 in 56K2SW332-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 56K2SW332-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 32A 500V three-phase circuits.
