1)
After responding, the resetting capability cannot be guaranteed. The protective function has been verified
up to the specified values. The low voltage limiter then represents a low-impedance connection (short
circuit).
2)
Up to this current value in the stated time period, the low voltage limiter resets itself back to its starting
condition after responding. If the current is higher than this or if the time period is greater than that stated,
the resetting capability cannot be guaranteed. If the low voltage limiter does not reset to its starting condition,
it becomes permanently conductive. In this way, the protective function continues to be fulfilled up to
parameters as stated at
1).
