Product details

Siemens 5SY4220-7 SENTRON MCB – Line-Down or Spec Fill

Breaking capacity covers most industrial panels: 10 kA per EN 60898-1, 20 kA per IEC 60947-2, and 5 kA per UL1077 for North American jobs. That's enough headroom for common fault levels in MCCs and distribution boards.

Environmental and Mounting Notes

Rated -40 to 75 °C ambient. Derate above 55 °C according to the humidity table: 95% RH up to 55 °C, then down to 35% RH at 75 °C. IP20 with conductors connected; sealable enclosure available (listed as 'Sealable: Yes'). Mount in any position. No neutral conductor switching – pure line-side protection.

Certified to IEC/EN 60898-1, IEC/EN 60947-2, and UL1077 (5 kA). Halogen-free and silicon-free construction. Energy limitation class 3.
