The Siemens 5SY6601-8 is a SENTRON miniature circuit breaker with a 1 A rated current and a D tripping characteristic, 4-pole (3P+N) configuration rated at 400 V AC.
The 4-pole unit occupies 4 width units (72 mm).
Humidity tolerance: 95% at 55 °C, derating to 35% at 75 °C. Halogen-free and silicon-free construction. Touch protection is built in. The part is sealable for tamper-proof installations. Approvals include EN 60898, IEC 60947-2, and UL 1077 / CSA C22.2 No. 235 (5 kA at AC).
30 kA per IEC 60947-2, 6 kA per EN 60898 at 400 V AC, and 15 kA per IEC 60947-2 at DC (72 V max). UL 1077 rating is 5 kA at AC.
Both are 4-pole SENTRON MCBs with the same DIN-rail footprint and 4 width units. The 5SY6601-8 is a 1 A D-curve; 5SY3132-6 is a different rating and curve. Panel fit is the same, but verify the current rating and tripping characteristic match the circuit design before substitution.
