Identifying This SKU - K1

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 56K1SW320-GY has K1 in the model number (locks in OFF position only)

Why it Matters

Three-Phase Isolation, Key-Controlled

The triple-pole design breaks all three active lines in a single operation, making it a true three-phase isolator rather than a switching function on one or two poles. The removable key adds an access-control layer that a rotary-only switch cannot provide, and the rotary handle also accepts two 8 mm padlocks in the OFF position for additional mechanical lock-out.

Weather-Sealed for Exposed Sites

The IP66 seal to AS 60529 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 exposed to dust and jetted water.

Compliant to Australian Standards

Manufactured to AS/NZS 3133, the 56K1SW320-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 56K1SW320-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 K1 in 56K1SW320-GY mean?
A: The K1 designation means the isolator locks in the OFF position only. The K2 variant locks in both ON and OFF positions.

Q: Is the 56K1SW320-GY supplied with a common key?
A: No. Without CK in the part number, the switch is supplied with a random key. CK-suffix variants use the common No 103 key but are not currently in our range.
