Why Choose the ABB 1SDA105149R1 KLC-A Castell Key Lock Open XT7?
The ABB 1SDA105149R1, designated KLC-A Castell Key lock open XT7, is a genuine ABB mechanical key lock accessory designed for SACE Tmax XT7 moulded-case circuit breakers. Part of the ABB Tmax XT 250 range, it provides the predisposition required for a Castell key locking arrangement that can secure the circuit breaker in the open position.
Key locking accessories provide an important mechanical safeguard in electrical distribution systems by helping prevent unauthorised or unintended circuit breaker operation. The KLC-A arrangement is particularly useful where controlled switching sequences, maintenance isolation or mechanical interlocking procedures form part of the installation's operating requirements.
The 1SDA105149R1 is specifically identified by ABB as a Castell key lock predisposition for the XT7 frame. It is supplied as a mechanical accessory within the SACE Tmax XT platform and is intended for professional low-voltage switchgear and power distribution installations requiring provision for Castell key locking.

Reliable Key Locking for Electrical Isolation
Key locking systems are commonly used in low-voltage switchgear to control circuit breaker operation and support defined electrical isolation procedures. Restricting operation through a trapped or controlled key arrangement can help ensure that switching takes place only when the required mechanical conditions have been satisfied.
The ABB 1SDA105149R1 provides the XT7 circuit breaker with the necessary predisposition for a Castell open-position key lock. This makes it suitable for switchboards and distribution systems where Castell key interlocking forms part of a wider operating, isolation or safety sequence.
Typical Applications
- ABB SACE Tmax XT7 circuit breaker installations.
- Industrial low-voltage switchboards.
- Commercial power distribution systems.
- Controlled electrical isolation arrangements.
- Castell key interlocking systems.
- Switchgear requiring mechanically controlled operating sequences.
