Product details

The Siemens 5SY4613-8 is a 4-pole (3P+N) SENTRON miniature circuit breaker with a D tripping characteristic, rated 13 A at 35 °C and 50/60 Hz.

The higher IEC figure gives you selectivity headroom downstream of a distribution board with a 25 kA or 36 kA upstream breaker — the 5SY4613-8 will clear a fault without the main breaker tripping, provided the let-through energy is coordinated.

Thermal derating and environmental range

Rated 13 A at 35 °C, the 5SY4613-8 derates to 12.38 A at 40 °C, 12.05 A at 45 °C, 11.73 A at 50 °C, 11.38 A at 55 °C, and 11.02 A at 60 °C. If your panel ambient sits at 50 °C, size the branch load to 11.73 A continuous, not the nameplate 13 A. The breaker itself survives -40 °C to 75 °C ambient and mounts in any orientation — useful for outdoor cabinets or unheated enclosures.

Frequently asked questions

Where can I buy the 5SY4613-8 and get a price?

It is sourced to order against an RFQ through independent distribution. Submit a quote request; availability and current pricing are confirmed at quote time.

What is the difference between the 5SY4613-8 and the 5SY4140-7?

The 5SY4140-7 is a 4-pole (3P+N) SENTRON MCB with a C tripping characteristic, rated 40 A. The 5SY4613-8 uses a D curve (higher inrush tolerance) and is rated 13 A. They share the same 4 MW DIN-rail footprint and terminal layout, so a panel wired for the 5SY4140-7 can accept the 5SY4613-8 without rewiring — but the load current and trip curve must match the circuit design.

What compliance documentation does Siemens provide for the 5SY4613-8?

The SENTRON series carries IEC/EN 60898 and IEC 60947-2 certifications. RoHS and REACH declarations are standard for current-production Siemens MCBs. The part is halogen-free and silicon-free per the spec.
