1SDA066610R1 ABB KLC XT3 Ronis Equal-Key Type A Key Lock

Why Choose the ABB 1SDA066610R1 KLC XT3 Ronis Key Lock?

The ABB 1SDA066610R1 is a Ronis key lock accessory for ABB SACE Tmax XT3 moulded-case circuit breakers, designed to provide controlled mechanical locking of the circuit breaker. Identified by ABB as KLC XT3 KEY LOCK RONIS EQ.FEL.A OP/CL, it forms part of the mechanical accessory range for the Tmax XT family.

This KLC key lock uses a Ronis equal-key Type A configuration and is designed for locking in both the open and closed positions. The key can be withdrawn in the open or closed position, providing a practical means of restricting circuit-breaker operation and supporting controlled access within industrial electrical installations.

Designed specifically for the ABB SACE Tmax XT3 frame, the 1SDA066610R1 integrates directly with compatible manual circuit breakers. Its dedicated ABB design makes it suitable for switchboards, distribution panels, machinery and other installations where secure mechanical control of an XT3 circuit breaker is required.

Secure Mechanical Control for XT3 Circuit Breakers

Circuit-breaker key locks provide a mechanical method of controlling access to switching operations. By restricting operation according to the lock and key arrangement, they can help prevent unintended or unauthorised changes to the operating state of a circuit breaker and support defined operating procedures within electrical installations.

The ABB 1SDA066610R1 is engineered specifically for the Tmax XT3 platform and provides a Ronis equal-key Type A arrangement with locking in the open and closed positions. This makes it particularly useful where multiple authorised operators or coordinated key-locking arrangements are required in industrial power distribution and machinery applications.

Typical Applications

• Industrial low-voltage switchboards.
• Electrical distribution panels.
• Machine control cabinets.
• Manufacturing and process equipment.
• OEM electrical systems.
• Installations requiring controlled operation of ABB Tmax XT3 circuit breakers.
