1SDA107497R1 ABB KLC-S Key Lock Open N.20007 for Tmax XT7M

Why Choose the ABB 1SDA107497R1 KLC-S Key Lock?

The ABB 1SDA107497R1 is a KLC-S key lock designed to lock ABB SACE Tmax XT7M circuit breakers in the open position. This dedicated mechanical accessory provides controlled locking of the circuit breaker to help prevent unintended closing while equipment or downstream circuits are intentionally isolated.

This KLC-S version features equal key number 20007, allowing multiple compatible XT7M circuit breakers fitted with the same numbered lock to share a common key arrangement. The key is removable with the circuit breaker in the open position, making the accessory particularly suitable for installations requiring coordinated access control and dependable electrical isolation procedures.

ABB order code 1SDA107497R1 is specifically designed for the SACE Tmax XT7M circuit-breaker platform. As an original ABB Tmax XT accessory, it provides a coordinated mechanical locking solution for industrial and commercial low-voltage distribution systems where controlled breaker operation is required.

Secure Isolation for Tmax XT Circuit Breakers

Key-locking accessories provide a mechanical means of controlling circuit-breaker operation during maintenance and isolation procedures. By securing a compatible XT7M circuit breaker in its open position, the KLC-S lock helps prevent accidental or unauthorised closing while the connected circuit or equipment is intended to remain isolated.

The equal-key N.20007 arrangement is particularly useful where several compatible circuit breakers need to operate within the same key group. This enables authorised personnel to use a common key across suitably configured breakers while retaining the dependable mechanical locking functionality of the ABB Tmax XT accessory system.

Typical Applications

• ABB SACE Tmax XT7M circuit-breaker installations.
• Industrial low-voltage switchboards.
• Commercial electrical distribution systems.
• Electrical isolation and maintenance procedures.
• Multiple circuit breakers requiring an equal-key locking arrangement.
• Power-distribution systems requiring controlled circuit-breaker operation.
