The SIEMENS 5SY4102-8 is a miniature circuit breaker designed for 230/400 V systems, providing single-pole protection with a D-characteristic tripping curve and a 2 A rating. It protects circuits against overloads and short circuits up to a 10 kA interrupting capacity, making it suitable for household and light commercial installations where selective tripping for inductive loads is needed. With a 70 mm device depth (D = 70 mm), it fits compact electrical panels and DIN-rail setups. Use it to maintain reliable circuit protection while minimizing space requirements in distribution boards.
