Secure Keyed Circuit-Breaker Isolation

A circuit-breaker key lock provides mechanical control over breaker operation by securing the device in a defined operating state. With the ABB 1SDA066606R1, the compatible XT3 circuit breaker can be locked in the open position, helping maintain electrical isolation during maintenance, inspection and controlled servicing procedures.

The equal-key Ronis Type A arrangement is particularly useful where compatible locking devices need to share the same key configuration. With the key removable while the XT3 breaker is open, the KLC accessory can support structured key-management and electrical isolation procedures across industrial power distribution systems.

Typical Applications

• ABB SACE Tmax XT3 moulded-case circuit breakers.
• Electrical switchboards and distribution panels.
• Maintenance and service isolation procedures.
• Industrial machinery and control panels.
• Power distribution systems requiring keyed breaker control.
