[Answer] Short-circuit capability, not less than 300%, 10 s — how should this be interpreted?

[Answer] Short-circuit capability, not less than 300%, 10 s — how should this be interpreted?

This is a requirement for the device’s characteristics under extreme conditions: when the current reaches 3 times (300%) the rated current, the device must be able to withstand it for 10 seconds without damage (the time needed for the protective device to disconnect the circuit).
