Why Choose the ABB 1SDA066595R1 KLC XT1 Ronis Type B Key Lock?

The ABB 1SDA066595R1 is a KLC Ronis key lock designed specifically for ABB SACE Tmax XT1 moulded-case circuit breakers. It provides mechanical locking of the circuit breaker in the open position, supporting controlled electrical isolation and helping prevent unintended breaker operation during maintenance or servicing.

This KLC accessory features equal Ronis Type B keys, providing a common-key arrangement for installations using compatible Type B locking devices. The key is withdrawable in the open position, making the accessory suitable for controlled isolation and key-management procedures.

As part of the ABB T-Max XT 250 Range, the 1SDA066595R1 is engineered for installation on the ABB Tmax XT1 circuit breaker. Its dedicated mechanical locking arrangement provides a practical solution for switchboards, machinery panels and low-voltage distribution systems where keyed control of breaker operation is required.
