Siemens SENTRON 5SY7608-7 — 4-pole MCB, C-curve, 8 A
The Siemens SENTRON 5SY7608-7 is a 4-pole miniature circuit breaker (3P+N) rated 8 A at 400 V AC, with a C tripping characteristic.
The EN figure governs residential/commercial distribution boards; the IEC figure applies when the breaker is used in industrial switchgear where higher fault currents are expected. At DC, the breaking capacity is 15 kA at 72 V max, so it also handles DC branch circuits within those limits.
Mounting and wiring — panel integration
