Frame 1×R8i
Maximum allowable prospective short-circuit current (I
cable must be equipped with fuses as follows:
• maximum 1250 A gG* for frame size R8i
*) Type gG according to IEC 60269
Maximum allowed operating time is <0.1 s for fuses mentioned above.
Frame R8i multiples:
Rated peak withstand current (I
breaker and earthing/grounding switch)
Rated short-time withstand current (I
circuit breaker and earthing/grounding switch)
The drive is suitable for use on a circuit capable of delivering not more than
100,000 rms symmetrical amperes at 600 V maximum when the input cable is
protected with class T fuses.
