1SDA066590R1

The 1SDA066590R1 PLL XT2-XT4 PADLOCKS DEVICE OPEN is a high-quality mechanical locking accessory designed by ABB for its prominent SACE Tmax XT series of Molded Case Circuit Breakers (MCCBs). This device acts as a fixed lock provision that permanently mounts to the front frame of compatible circuit breakers. It is specifically engineered to safely lock the circuit breaker mechanism only when it is in the OFF (Open) position, preventing accidental re-energization during downstream system maintenance or standard maintenance procedures (LOTO—Lockout/Tagout).
