Why Choose the ABB KLC-S Key Lock Open N.20009 E2.2...E6.2?
The ABB KLC-S Key Lock Open N.20009 E2.2...E6.2, order code 1SDA073796R1, is a mechanical key-locking accessory designed for compatible ABB SACE Emax 2 E2.2, E4.2 and E6.2 air circuit breakers. It provides a dedicated means of locking the circuit breaker in the open position, helping prevent unintended or unauthorised closing.
The KLC-S accessory provides a mechanical operating restriction independent of the circuit breaker's electrical control system. This makes it suitable for switchgear maintenance, isolation procedures and operating schemes where the breaker must remain securely open until the appropriate key-operated release procedure is completed.
This version features the specific N.20009 key coding, enabling the correct lock variant to be selected for the required switchgear key scheme. As part of the SACE Emax 2 accessory platform, the 1SDA073796R1 provides an ABB-engineered mechanical locking solution for demanding low-voltage power distribution installations.

Secure Open-Position Circuit Breaker Locking
Open-position key locking provides a physical method of keeping a circuit breaker open until the authorised key-operated procedure has been completed. The mechanism can support maintenance, isolation and controlled switching procedures by preventing the breaker from being closed while the lock is engaged.
The ABB 1SDA073796R1 combines this mechanical locking function with the defined N.20009 key coding for compatible Emax 2 E2.2, E4.2 and E6.2 circuit breakers. Its dedicated design makes it suitable for switchgear installations where a specific key code is required as part of the operating and access-control arrangement.
Typical Applications
- ABB SACE Emax 2 E2.2, E4.2 and E6.2 air circuit breakers.
- Circuit-breaker open-position locking.
- Controlled switchgear maintenance procedures.
- Electrical isolation and operating procedures.
- Industrial low-voltage distribution switchboards.
- Commercial and infrastructure power distribution systems.
