Product details

The Siemens 5SY4604-8CC11 is a SENTRON miniature circuit breaker rated 4 A with a D tripping characteristic, 4-pole configuration (3P+N), and a 10 kA breaking capacity at 400 V AC. The D-curve tolerates high inrush currents without nuisance tripping while clearing faults up to 10 kA. The neutral pole is switched, and the unit is sealable for tamper-proof installations.

The 4 A D-curve rating protects circuits feeding inductive loads where the starting surge can be high. The 4-pole 3P+N design switches all three phases and the neutral. Terminal torque spec is 2.5–3.5 N·m. IP20 with connected conductors.

Frequently asked questions

What is the closest functional second-source to 5SY4604-8CC11?

The 5SY6602-8 is a functional peer in the same SENTRON family, but verify the tripping characteristic and pole count match your application — the 5SY4604-8CC11 is a 4 A D-curve 4-pole unit, while the peer may differ in current rating or poles. Panel fit (DIN rail, same width units) is compatible, but always confirm the specific ratings before substituting.

What is 5SY4604-8CC11's listed depth?

The depth is 76 mm, with an installation depth of 70 mm.

What wire sizes does 5SY4604-8CC11 accept?

It accepts solid and stranded conductors from 0.75 mm² up to 35 mm².

What compliance documentation does Siemens provide for 5SY4604-8CC11?

The part carries a railway design designation and is halogen-free and silicon-free. Standard Siemens declarations (CE, UKCA) apply per the SENTRON series. For specific RoHS/REACH certificates or UL listing status, request the manufacturer's declaration at quote time.
