Reset fault simply bygiving a new start signal.)RecommendedFuse Type*Two levels of short circuit protection can be provided by the user:1. Type 1 protection is available where the short circuit protective device protects the wiring and theintegrity enclosure. The soft starter will probably damage and require replacement or repair beforebeing re-energized. Circuit breakers and motor circuit protectors provide this type of protection.2. Type 2 protection is available where the short circuit protective device protects both the wiring and thesoft starter. The soft starter should not require repair before re-energizing after the short circuit has beencleared. Fuses of an KR-1 type or HRC-1 type sized in accordance with the NEC/CEC code or SITORsemiconductor type fuses provide this kind of protection.* For a complete listing of <strong>Siemens</strong> SITOR fuses, see Appendix A.24 3ZX1012-0RW34-1AN1
