A: Common configurations are in stock for 5-7 day shipping; custom specs take 4-6 weeks.
Q: Does it come with a test report?
A: Every ABB VCB includes the original factory routine test report.
Q: Is the VM1 better than the VD4?
A: The VM1 is superior for high-frequency operations, while the VD4 is preferred for standard utility applications due to its purely mechanical nature.
Q: What accessories are included as standard?
A: Standard breakers include basic auxiliary contacts; charging handles and coils are pre-installed.
Q: How do you handle shipping for such heavy equipment?
A: We use reinforced IPPC-certified seaworthy wooden crates with internal shock absorption.
