Product details

It protects branch circuits against overload and short-circuit in industrial control panels, switchgear, and distribution boards.

Breaking capacity and standards

This MCB carries a 15 kA rated short-circuit capacity per EN 60898-1 and 30 kA per IEC 60947-2, with a DC breaking capacity of 15 kA per IEC 60947-2 at 60 V. It also complies with UL1077, making it accepted in North American supplementary-protection applications. The dual rating means it can be specified for IEC panels (30 kA at the bus) while still fitting UL-listed machinery.

Thermal derating and ambient limits

Rated current is 10 A at 35 °C, but derates progressively: 9.39 A at 40 °C, 9.07 A at 45 °C, 8.74 A at 50 °C, 8.4 A at 55 °C, and 8.04 A at 60 °C. The ambient operating range spans -40 °C to 75 °C, with humidity limits of 95% up to 55 °C, 55% up to 70 °C, and 35% at 75 °C.

Frequently asked questions

Where can I buy 5SY7210-8 and get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing.

What compliance documentation does Siemens provide for 5SY7210-8?

The breaker is certified to IEC/EN 60898-1, IEC/EN 60947-2, and UL1077. It is halogen-free and silicon-free.

What is the difference between 5SY7210-8 and 5SY4140-7?

The 5SY4140-7 is a 1-pole B-curve breaker (lower inrush tolerance), while the 5SY7210-8 is a 2-pole D-curve breaker for high-inrush loads. They are not drop-in interchangeable; the pole count and trip characteristic differ.
