Siemens 5SY6106-7 Safety Relay Module

Siemens 5SY6106-7 is a single-pole miniature circuit breaker (MCB) from the SENTRON family, designed to protect 230/400 V AC circuits from overload and short-circuit conditions. The device is rated for a nominal current of 6 A, uses a C-type tripping curve, and provides a short-circuit breaking capacity of 6 kA (Icu), making it suitable for general purpose protection in small- to medium-load distribution and control applications. As a 1-pole unit, the 5SY6106-7 is identified by the model designation 5SY6106-7 and the catalog notes a depth of approximately 70 mm, reflecting its compact footprint in standard electrical assemblies. This Siemens breaker is intended for installation where reliable, calibrated short-circuit and overload protection are needed for AC circuits, including lighting, power supplies, and simple automation circuits, helping to prevent wiring damage and equipment failure by rapidly interrupting current when a fault occurs. The 5SY6106-7 specification from Siemens is part of the broader SENTRON family of protective devices, known for consistent performance in modular, compact protection solutions.
