1SDA062156R1 ABB KLF-S-FP Key Lock 20007 for T7-T7M

Why Choose the ABB 1SDA062156R1 KLF-S-FP Key Lock?

The ABB 1SDA062156R1 is a dedicated fixed-part key lock accessory designed for compatible ABB SACE Tmax T7 and T7M circuit breaker systems. Identified by ABB as KLF-S-FP KEY LOCK 20007 CON/IS T7-T7M, it provides keyed mechanical locking for the fixed part of compatible withdrawable circuit breaker installations.

As part of the ABB SACE Tmax T accessory range, the KLF-S-FP locking system is intended for applications where circuit breaker racking or operating positions need to be mechanically secured. The key-operated mechanism provides controlled access to the breaker arrangement and helps prevent unauthorised or unintended movement during normal operation, isolation or maintenance procedures.

The 1SDA062156R1 uses a same-key KLF-S configuration with key code 20007. This defined key code makes the accessory suitable for installations requiring coordinated keyed access across compatible ABB locking devices while maintaining a specific key identity within the switchgear system.

Secure Position Control for Withdrawable Circuit Breakers

Key locking accessories provide a mechanical means of controlling the position of withdrawable circuit breakers within their fixed parts. By requiring the appropriate key before the breaker can be moved from a secured condition, the locking system supports controlled operating and maintenance procedures within low-voltage switchgear.

The ABB 1SDA062156R1 uses a same-key 20007 configuration, allowing compatible ABB locking devices with the corresponding key code to form part of a coordinated access arrangement. This makes the accessory suitable for switchboards where controlled breaker positioning and consistent keyed access are required.

Typical Applications

• ABB SACE Tmax T7 and T7M withdrawable circuit breaker installations.
• Industrial low-voltage switchboards.
• Circuit breaker position control and isolation procedures.
• Power distribution systems requiring keyed mechanical locking.
• Switchgear maintenance and access control arrangements.
• Commercial and industrial electrical distribution systems.
