The ABB 1SDA066620R1 is a Ronis key lock accessory for Tmax XT moulded-case circuit breakers, designed to provide secure locking of compatible circuit-breaker operating mechanisms. As part of the ABB Tmax XT mechanical accessory range, it is suitable for XT1, XT2, XT3 and XT4 circuit-breaker frames and is designed for use with rotary handle operating mechanisms and front-panel operating arrangements.
This RHL key lock uses an equal-fellow Type C key configuration, meaning compatible Type C locks can use the same key arrangement. The mechanism is designed to lock the associated operating mechanism in the open position, supporting controlled electrical isolation and helping prevent unauthorised or unintended circuit-breaker operation.
The 1SDA066620R1 is designed for ABB Tmax XT1, XT2, XT3 and XT4 circuit breakers and can be used with compatible rotary handle and front-panel operating mechanisms. Its Ronis locking system makes it particularly useful in switchboards containing multiple circuit breakers where coordinated key-controlled access and isolation are required.
Key locking accessories provide a controlled mechanical method of restricting circuit-breaker operation. By locking the associated operating mechanism in the open position, the ABB 1SDA066620R1 can support electrical isolation procedures and help prevent unintended operation while equipment or downstream circuits are being maintained.
The equal-fellow Type C Ronis configuration is particularly useful where several compatible locks need to operate with the same key arrangement. Combined with compatibility across Tmax XT1 through XT4 frame sizes, this provides a practical locking solution for switchboards containing multiple ABB Tmax XT circuit breakers.
