Siemens 5SX2102-8 Circuit Breaker

Siemens 5SX2102-8 is a DIN-rail-mounted circuit breaker from the 5SX family, engineered to provide overcurrent protection in industrial control panels. The model is listed as a 1-pole device with a 6 kA interrupt rating, making it suitable for protecting individual feeders in compact control enclosures. Manufactured by Siemens, the 5SX2102-8 is commonly used in automation cabinets to guard circuits that feed motors, sensors, and control logic, delivering short‑circuit protection within a compact footprint in low‑voltage distribution layouts. The DIN-rail mounting compatibility and Siemens‑wide ecosystem of protective devices help ensure consistent integration with other Siemens control components and housing configurations. As part of Siemens' legacy protection line, this variant supports standard panel protection tasks in industrial environments and can be selected when a compact, factory‑tested protection device is required for a specific branch circuit within a distributed control system.
