3-Pole design C-curve tripping 6kA interrupting capacity 400V AC rating DIN rail mountable Three-phase circuit protection

Product description

The Siemens 5SX23 series consists of 3-pole miniature circuit breakers (MCBs) designed for comprehensive overcurrent and short-circuit protection. These breakers feature a C-curve tripping characteristic, a breaking capacity of 6kA, and an operating voltage of 400V AC. They are engineered to offer robust protection across three conductors simultaneously.

These 3-pole MCBs are commonly used in industrial and commercial applications, particularly for protecting three-phase loads such as motors, transformers, and three-phase power distribution circuits. Their design ensures simultaneous disconnection of all three phases for enhanced safety.

Stanlo Automation, a veteran-owned surplus parts distributor, offers a selection of Siemens 5SX23 series circuit breakers. We are committed to providing reliable components and efficient service to support your automation needs.
