Siemens 5SY6-202-8 Circuit Breaker

Siemens 5SY6-202-8 is a two-pole SENTRON miniature circuit breaker designed for AC mains protection up to 400 V. It is rated for 2 A and uses a D-type trip characteristic, delivering fast short-circuit protection while tolerating normal overloads on small branch circuits. This molded-case breaker belongs to Siemens’ 5SY6 family and is also cataloged as 5SY62028. With a rated short‑circuit breaking capacity of 6 kA at 400 V, it supports reliable protection for modest loads in compact two‑pole configurations. The device is intended for use in Siemens protection schemes and fits standard enclosure and panel layouts that accept SENTRON 5SY6 devices. Operating ambient temperature is rated up to 45°C and 50–60 Hz operation. Typical users include electrical contractors seeking compact, UL 1077 and CSA 22.2 listed protection for lighting and receptacle circuits in commercial or light-industrial installations. Common applications include lighting circuits, receptacle circuits, and other small electrical loads where precise 2 A protection is required.
