1SDA107498R1 ABB KLC-S Key Lock Open N.20008 XT7M

Why Choose the ABB 1SDA107498R1 KLC-S Key Lock?

The ABB 1SDA107498R1 is a KLC-S key lock in open position designed specifically for the ABB Tmax XT7M moulded-case circuit-breaker platform. Identified by key number N.20008, it provides a mechanical locking solution for securing the circuit breaker in the open position.

The KLC-S configuration uses the same key for a defined group of circuit breakers, making it particularly useful where several compatible XT7M breakers need coordinated key-locking arrangements. Locking the breaker in the open position helps prevent unauthorised or unintended closing during operating or maintenance procedures.

As a dedicated ABB Tmax XT mechanical accessory, the 1SDA107498R1 is purpose-designed for the XT7M frame and integrates with the circuit breaker's operating mechanism. It is suitable for switchboards and power-distribution systems where controlled access and mechanical interlocking form part of the installation's operational safety strategy.

Controlled Open-Position Locking for Tmax XT7M

Open-position key locking provides a physical means of preventing a circuit breaker from being closed while the locking arrangement is engaged. This can support operating and isolation procedures by ensuring that access to the closing function is controlled by possession of the appropriate key.

The ABB 1SDA107498R1 uses the KLC-S same-key arrangement with key number N.20008. This configuration is useful where multiple compatible circuit breakers are intended to form part of the same keyed group, providing a consistent mechanical locking solution across suitable XT7M installations.

Typical Applications

• ABB Tmax XT7M circuit-breaker installations.
• Industrial low-voltage distribution switchboards.
• Controlled electrical isolation arrangements.
• Power-distribution and control panels.
• Manufacturing and process facilities.
• Commercial and infrastructure electrical systems.
• Installations requiring same-key locking across designated circuit-breaker groups.
