Siemens 5SY4213-7CC SENTRON MCB — 2-pole C13, 10 kA
For UL 1077 / CSA C22.2 No. 235 installations, the interrupting rating is 5 kA — a key distinction when specifying for North American panels.
The 13 A rating holds at 35 °C ambient. At 40 °C it derates to 11.95 A, at 45 °C to 11.38 A, at 50 °C to 10.78 A, and at 55 °C to 10.15 A. If the panel runs hot — common in sealed enclosures or adjacent to heat-generating drives — use the 40 °C column for sizing. The breaker operates from -40 °C to 75 °C ambient, with humidity limits of 95% up to 55 °C, 55% up to 70 °C, and 35% at 75 °C.
The 5SY4213-7CC carries IEC 60898 certification for the 10 kA breaking capacity and UL 1077 / CSA C22.2 No. 235 for the 5 kA rating. It is halogen-free and silicon-free, and designated per IEC 81346-2 and DIN EN 61346-2 as function F (protective device). Vibration resistance per IEC 60068-2-6 is ±1 mm at 5 to 25 Hz and 50 m/s² at 25 to 150 Hz. The manufacturer provides RoHS and REACH declarations with the shipment.
