Product details

The Siemens SENTRON 5SY8513-8 is a 2-pole miniature circuit breaker (1P+N) rated 13 A at AC with a D tripping characteristic, designed for high-inrush loads like motor starters and transformers where the starting surge exceeds the magnetic threshold of a C-curve breaker. Its 30 kA breaking capacity per IEC 60947-2 at 50/60 Hz means it can safely interrupt fault currents up to that level without cascading upstream — a key spec for industrial panels where the prospective short-circuit current is high.

The 36 mm width (2 modular units) snaps onto standard DIN rail via the quick assembly system, and the 76 mm depth leaves clearance for a 70 mm installation depth in the enclosure.

The 30 kA breaking capacity at AC per IEC 60947-2 is the figure that governs fault clearance in a 400 V industrial panel; the 15 kA DC rating per the same standard covers battery-backed DC bus circuits. UL 1077 and CSA C22.2 No. 235 recognition at 5 kA supports North American panel acceptance.

Frequently asked questions

How do I get current pricing and availability for 5SY8513-8?

Pricing and stock are confirmed at quote time. Submit an RFQ against this order code; we source through independent distribution and quote to your required quantity and delivery window.

What is the breaking capacity of 5SY8513-8?

30 kA at AC per IEC 60947-2, 15 kA at DC per IEC 60947-2, and 5 kA per UL 1077 / CSA C22.2 No. 235. The 30 kA AC figure is the one that matters for most industrial 400 V panels.

What is the tripping characteristic of 5SY8513-8?

D-curve, meaning the magnetic trip operates between 10× and 20× In. This holds through motor inrush and transformer energization without nuisance tripping, while still clearing a hard fault fast.

Will 5SY8513-8 drop into a panel specified around 5SY7210-7CC without rewiring?

Both are 2-module-width (36 mm) DIN-rail MCBs, so the footprint and busbar pitch match. However, the 5SY8513-8 is a 2-pole 1P+N breaker with internal neutral switching, while the 5SY7210-7CC is a single-pole unit. If the panel was wired for a 1-pole breaker with a separate neutral bar, the 1P+N construction of the 5SY8513-8 requires the neutral to pass through the breaker — verify the wiring scheme before swapping.
