ABB RHE 1SDA066479R1 XT1-XT3 Returned Handle Extension

The ABB RHE XT1-XT3 F/P STAND. RETURNED (article 1SDA066479R1) is a rotary handle operating mechanism for ABB Tmax XT1 and XT3 circuit breakers installed in fixed or plug-in configurations. It mounts on the enclosure door and actuates the breaker via an adjustable-depth cable assembly rated at 500 mm, with a standard returned handle action. A built-in padlock device and door interlock are included for safe operation and controlled access.

Technical specifications:

• Series: RHE XT1-XT3 F/P STAND. RETURNED
• ABB article number: 1SDA066479R1
• EAN: 8015644692919
• Compatible circuit breakers: ABB Tmax XT1 and XT3
• Mounting type: Fixed and Plug-in (F/P)
• Cable length: adjustable, L=500 mm
• Handle action: standard returned (returns to original position after operation)
• Padlock device: included
• Door interlock: included

Features and benefits:

• 500 mm adjustable-depth cable gives flexibility when positioning the door handle relative to the circuit breaker inside the enclosure
• Padlock device allows lockout/tagout procedures to be applied directly at the handle, preventing unintended switching during maintenance
• Door interlock prevents the enclosure door from being opened while the breaker is in the ON position, reducing exposure to live parts
• Standard returned handle action means the grip automatically resets after each operation, reducing the risk of misreading the breaker state
• Single accessory covers both fixed and plug-in XT1/XT3 breaker variants, avoiding the need for separate part numbers

Applications:

• Industrial motor control centres and distribution boards where the circuit breaker must be operated from the closed enclosure door
• Switchgear panels subject to lockout/tagout safety requirements during maintenance or servicing
• Installations where physical separation between operator and live components is a design requirement
• Fixed-mounted or plug-in XT1/XT3 breaker assemblies in production, utilities, or building services environments
