Why Choose the ABB 1SDA105073R1 KLC XT7 Ronis Key Lock?
The ABB 1SDA105073R1, designated KLC XT7 KE.LO. RONIS EQ.C 1228 OPxB, is a genuine ABB Ronis key lock accessory designed for SACE Tmax XT7 circuit breakers. It provides a mechanical locking function that secures the compatible circuit breaker in the open position, helping prevent unauthorised or unintended closing during isolation, maintenance and controlled operating procedures.
This KLC accessory uses a Ronis equal Type C key arrangement with lock code 1228. ABB specifies the key as withdrawable when the circuit breaker is in the open position, providing a defined mechanical interlocking condition for applications where controlled access to breaker operation is required.
Purpose-designed for the ABB SACE Tmax XT7 platform, the 1SDA105073R1 integrates with the circuit-breaker operating mechanism as a dedicated locking accessory. With a net weight of approximately 0.064 kg, it provides a compact manufacturer-engineered solution for switchboards and power distribution systems requiring secure open-position locking.

Controlled Open-Position Locking for XT7 Circuit Breakers
Circuit-breaker key locks provide a mechanical means of restricting operation according to a defined switchgear procedure. An open-position key lock prevents the associated breaker from being closed while the locking condition is active, supporting controlled isolation and helping ensure that switching operations follow the intended sequence.
The ABB 1SDA105073R1 provides this functionality for the SACE Tmax XT7 using a Ronis equal Type C 1228 key arrangement. The key can be withdrawn with the breaker locked in the open position, making the accessory suitable for switchgear applications where key-controlled access, mechanical interlocking or operational sequencing is required.
Typical Applications
- ABB SACE Tmax XT7 circuit-breaker installations.
- Key-controlled electrical isolation systems.
- Industrial low-voltage switchboards.
- Power distribution and protection systems.
- Mechanical interlocking and operating-sequence applications.
- Maintenance procedures requiring secure open-position circuit-breaker locking.
