Siemens 5SY6-116-7 Circuit Breaker

Siemens SENTRON 5SY6-116-7 is a 1-pole miniature circuit breaker (MCB) in the SENTRON 5SY6 family, engineered for single-branch overcurrent protection in low-voltage distribution systems. The unit is rated for 16 A and uses a Type C curve, tripping on modest overloads and short circuits to protect wiring and connected loads. It is specified for 400 V AC operation and provides a DC rating up to 72 V, with a breaking capacity of 6 kA at 400 V AC, enabling safe interruption of fault currents in typical commercial and residential wiring schemes. This compact, single-pole device protects individual circuits within panels or distribution boards, supporting selective coordination with upstream protections to minimize nuisance tripping. As part of the Siemens SENTRON portfolio, the 5SY6-116-7 offers a standardized form factor that simplifies sourcing, replacement, and cross-compatibility across other 5SY6 devices and panel components. It is suitable for installation in standard low-voltage electrical installations where reliable plug-in protection is required for single-phase circuits, such as lighting, outlets, or small appliance circuits within a broader protection scheme. The 5SY6 series is widely used in modern electrical installations for its consistency with Siemens’ protective devices and ease of integration with compatible panel boards and accessories.
