It is rated 13 A at 30 °C and carries a 10 kA breaking capacity per EN 60898 and 20 kA per IEC 60947-2, meaning it can safely interrupt fault currents up to those levels without upstream cascading.
Temperature derating — the real-world current rating
At 40 °C it derates to 12.48 A, at 50 °C to 11.96 A, and at 70 °C to 10.01 A.
Supply can enter from either the top or bottom.
Compliance and approvals
The 5SU1324-6KX13 is halogen-free and silicon-free. The energy limitation class is 3.
