❓ Frequently Asked Questions

1. Why choose a Vacuum Circuit Breaker over SF6 for outdoor use?
Vacuum circuit breakers require significantly less maintenance and are environmentally superior as they do not use greenhouse gases. They are also more compact and offer higher mechanical endurance.
2. What is the typical lifespan of a Dehler OVCB?
Our breakers are designed for a mechanical life of up to 20,000 operations and an electrical life of 10-15 years depending on the switching frequency and environment.
3. How do you ensure quality during mass production?
Every unit undergoes routine tests including power frequency withstand voltage, circuit resistance measurement, and mechanical characteristic tests before leaving the factory.
4. Can your products be integrated with existing SCADA systems?
Yes, our intelligent terminal units (FTU/DTU) support various communication protocols like Modbus and DNP3 for seamless remote integration.
