FAQ
Frequently Asked Questions
What is a vacuum circuit breaker?
Uses vacuum insulation to extinguish arcs. Superior to SF6 (environmental) and air (slower quenching). Sealed for life.
Why VCB over SF6?
No greenhouse gas, 2x longer life, no gas monitoring, faster arc quenching. SF6 phased out by EU F-Gas.
Certifications?
IEC 62271-100 type test, CQC, CE. Full test reports available.
Lead time?
Standard VCB: 2-3 weeks. Custom panels: 4-6 weeks. FOB Shanghai.
Embedded poles for panel builders?
Yes. Standard ZN63/VS1 dimensions. OEM/ODM. Custom coil voltages.
