Product details

The Siemens SENTRON 5SY8616-8 is a 4-pole (3P+N) miniature circuit breaker with a D tripping characteristic, rated 30 kA breaking capacity at 400 V AC per IEC 60947-2 and 15 kA at 60 V DC. It also carries a UL1077 listing for 5 kA at 400 V AC, covering North American supplementary-protection applications. Any mounting position, IP20 with conductors connected, and the combined top/bottom terminals simplify busbar or cable entry from either direction.
