1 year warranty
The Siemens 5SY4302-7 is a three-pole miniature circuit breaker from the SENTRON 5SY4 product family, designed for overcurrent and short-circuit protection in industrial and commercial electrical installations. It features a Type C tripping characteristic, making it suitable for applications with moderate inrush currents such as lighting circuits and general distribution. The device is rated for 2 A nominal current and 400 V AC operation, with a breaking capacity of 10 kA according to EN 60898 and 35 kA according to IEC 60947-2. It is UL 1077 rated as a supplementary protector for enhanced circuit protection. The breaker mounts on standard 35 mm DIN rail and offers a compact 70 mm depth design with halogen-free, silicon-free construction. It provides IP20 protection class when conductors are connected and supports installation of supplementary devices for extended functionality.
