Breaking capacity is rated 10 kA per EN 60898-1 and 35 kA per IEC 60947-2, with a DC rating of 15 kA per IEC 60947-2 at 60 V. The higher 35 kA figure applies under the industrial standard — useful when the fault current at the panel is known to exceed the residential 10 kA threshold. For UL 1077 / CSA C22.2 No.235 recognition, the interrupting rating is 5 kA.
Mounting position is any, so vertical or horizontal rail orientation works.
Listed as current production. The 5SY4106-8 carries IEC/EN 60898-1 and IEC/EN 60947-2 approvals, plus UL 1077 / CSA C22.2 No.235 recognition. Halogen-free and silicon-free construction. Pollution degree 3, overvoltage category III. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz.
