2-Pole design C-curve tripping 6kA interrupting capacity 400V AC rating DIN rail mounting Overcurrent and short-circuit protection

Product description

The Siemens 5SX22 series comprises 2-pole miniature circuit breakers (MCBs) designed for robust overcurrent protection in various electrical installations. These breakers feature a C-curve tripping characteristic, a 6kA breaking capacity, and a rated voltage of 400V AC. They are engineered to provide reliable safeguarding against short circuits and overloads for two circuits simultaneously.

These 2-pole MCBs are widely utilized in systems where both live and neutral conductors require simultaneous switching, such as in certain European power distribution systems or for protecting specific equipment. Applications include residential, commercial, and industrial settings for branch circuit protection.
