1SDA066298R1 ABB KL-D Ronis Key Lock for Tmax XT2-XT4 Withdrawable Fixed Part

Why Choose the ABB 1SDA066298R1 KL-D Ronis Key Lock?

The ABB 1SDA066298R1 is a genuine KL-D Ronis key-lock accessory designed for the fixed part of compatible withdrawable ABB SACE Tmax XT2 and XT4 circuit breakers. Identified by ABB as KL-D RONIS FP W XT2-XT4 KEY LOCK SEV., it provides a mechanical locking solution for controlled breaker positioning and access within low-voltage switchgear.

The accessory is intended for the fixed part (FP) of withdrawable (W) XT2 and XT4 installations, where mechanical key locking is required as part of an operating, maintenance or interlocking procedure. Its Ronis lock mechanism provides a robust physical means of restricting circuit-breaker movement or access to the relevant operating position.

The KL-D configuration is supplied for separate-key locking arrangements, making it suitable for switchboards where independently keyed locking points are required rather than a common equal-key system. As a genuine ABB Tmax XT accessory, the 1SDA066298R1 is designed for coordinated integration with the intended breaker platform.

Key Advantages

• Dedicated Ronis mechanical key lock for ABB SACE Tmax XT equipment.
• Compatible with the fixed part of withdrawable XT2 and XT4 circuit breakers.
• KL-D separate-key configuration supports independently keyed locking arrangements.
• Helps control circuit-breaker positioning during operation and maintenance.
• Mechanical locking function requires no external electrical supply.
• Genuine ABB accessory engineered for coordinated switchgear integration.

Mechanical Locking for Withdrawable Tmax XT Installations

Withdrawable circuit breakers allow the breaker moving part to be inserted into or removed from a fixed switchboard interface. Mechanical key locks are commonly used in these systems to control when movement or operation is permitted, helping maintain defined equipment states during maintenance, servicing and normal switching procedures.

The ABB 1SDA066298R1 provides a dedicated Ronis separate-key locking solution for compatible Tmax XT2 and XT4 fixed parts. Its KL-D arrangement is particularly suitable where individual locking points need to remain independently keyed within a broader switchgear control or interlocking scheme.

Typical Applications

• ABB SACE Tmax XT2 withdrawable circuit-breaker installations.
• ABB SACE Tmax XT4 withdrawable circuit-breaker installations.
• Industrial low-voltage switchboards.
• Commercial electrical distribution systems.
• Controlled breaker-positioning arrangements.
• Switchgear requiring independently keyed mechanical locking.
