Siemens 5SY6202-7 U 2A 2P 400V Electrical Contactor

Siemens 5SY6202-7 U is a 2-pole miniature circuit breaker (MCB) from the SENTRON 5SY6 family, engineered to provide reliable overcurrent protection for 400 V AC circuits. It carries a nominal current rating of 2 A and features a curve C trip characteristic, suitable for general-purpose protection of moderately inductive and resistive loads. With a short-circuit breaking capacity of 6 kA, the device can safely interrupt overloads and faults on typical distribution networks. The unit is designed for DIN-rail mounting and has a depth of 70 mm, enabling compact installation in control panels and distribution boards. As a 2P device, it protects two conductors simultaneously, making it appropriate for protecting single-line circuits or split-phase installations in residential, commercial, and light industrial applications. The 5SY6202-7 is commonly used in panelboards where space efficiency and standardization on the Siemens SENTRON line are important, providing a consistent form factor with other 5SY6 MCBs for easy cross-compatibility and replacement in existing assemblies.
