1SDA105065R1 ABB KLC XT5-XT6 RONIS 1228 Type D Key Lock

Why Choose the ABB KLC XT5-XT6 RONIS Type D Key Lock?

The ABB 1SDA105065R1, designated KLC XT5-XT6 KE.LO. RONIS EQ.D 1228 OPxB, is a RONIS key lock accessory designed for ABB SACE Tmax XT5 and XT6 moulded-case circuit breakers. It provides a mechanical locking function that allows the compatible circuit breaker to be secured in the open position, helping control operation during maintenance, isolation and authorised-access procedures.

As part of the ABB SACE Tmax XT mechanical accessory range, this KLC key lock uses the RONIS 1228 locking system with equal Type D keys. The key is withdrawable when the circuit breaker is in the open position, providing a defined mechanical interlocking arrangement for compatible XT5 and XT6 installations.

The 1SDA105065R1 is specifically designed for ABB SACE Tmax XT5 and XT6 circuit breakers. Its equal-key Type D configuration is particularly useful where compatible locking devices need to share the same key type, while the open-position key withdrawal arrangement supports controlled isolation within industrial switchboards and power-distribution systems.

Reliable Mechanical Locking for Circuit Breakers

Circuit-breaker key locks provide a mechanical means of controlling breaker operation and can be used to secure a breaker in a defined position. In industrial distribution systems, this type of accessory supports controlled isolation procedures by restricting operation until the appropriate key is available.

The ABB 1SDA105065R1 is configured to lock compatible SACE Tmax XT5 and XT6 circuit breakers in the open position, with the RONIS Type D key removable in that state. Its keyed-alike configuration allows compatible Type D locking devices to use matching keys where the electrical system design requires this arrangement.

Typical Applications

• ABB SACE Tmax XT5 and XT6 circuit-breaker installations.
• Industrial low-voltage switchboards.
• Electrical isolation and maintenance arrangements.
• Power-distribution panels and switchgear.
• Machinery and plant electrical systems.
• Applications requiring keyed-alike Type D circuit-breaker locking.
