Line fuse
Fuse protection against overload and short circuit
Every drive controller in the compound DC link system supplied with power must be protected by a fuse at the mains input by both overload and short circuit
protection connected in series. A miniature circuit breaker protects against overload and a safety fuse against short circuit.
Information
To ensure problem-free operation, always comply with the recommended trigger limits and trigger
characteristics of the fuse elements.

Type: SIRUS, Art.No.: 3RV 1041-4KA10
Trigger characteristic: 57 A – 75 A
b)
a) Reduces the input current from 73 A to 63 A. This causes the power output to be reduced, however reliable rectifier protection is not guaranteed.
b) Circuit breaker size S3, CLASS 10, adjustable current range: 57 A – 75 A, electromagnetic triggering: 975 A. Rectifier diodes are not protected in the range of 2 times to 13 times the nominal current.
