Product details

The Siemens 5SY4603-7CC is a SENTRON 5SY4CC-series miniature circuit breaker — a 4-pole (3P+N), C-curve device rated at 3 A with a 10 kA breaking capacity at 400 V AC per EN 60898.

Panel fit and terminal work

Terminals accept solid or stranded copper from 0.75 mm² up to 35 mm², with a tightening torque of 2.5 to 3.5 N·m. Both top and bottom terminals are combined (line/load reversible), and the unit is sealable for anti-tamper applications.

Environment and approvals

The IP20 rating applies with conductors connected — the front face is touch-protected. Breaking capacity is 10 kA per EN 60898 at 400 V AC, and 5 kA per UL 1077 / CSA C22.2 No. 235. Overvoltage category III, energy limiting class 3.
