Application-Specific FAQ
Q: Can the 3VU1300-1MH00 be used for motor protection in a star-delta starter?
A: Yes. The 3VU1300-1MH00 is suitable as the main circuit breaker in star-delta configurations when correctly sized for the motor’s full-load current.
Q: Is this circuit breaker compatible with SIEMENS 3RT contactors?
A: Yes. The 3VU Series is designed for direct coordination with SIEMENS 3RT contactors, enabling Type 2 coordination per IEC 60947-4-1.
Q: What is the difference between 3VU and 3RV series?
A: The 3VU series is an earlier generation of SIEMENS motor protection circuit breakers. The 3RV2 series is the current-generation replacement with enhanced features. Konmask.com stocks both — contact us if you need a cross-reference.
Q: Can I get a certificate of conformity or test report?
A: Yes. Original SIEMENS certificates of conformity are available upon request for OEM and EPC customers.
Q: Do you ship internationally?
A: Yes. We ship globally from China with DHL, FedEx, and UPS express options. Customs documentation and HS code support included.
