FAQs
What is a 33 KV out door breaker?
It’s a medium-voltage circuit breaker designed for outdoor use to control and protect electrical networks operating at 33 kilovolts. It isolates faults and switches loads safely under high-voltage conditions.
How is a 33 KV out door vacuum circuit breaker different?
Vacuum interrupters are used by vacuum circuit breakers to eliminate arcs. They offer fast switching, low maintenance, and longer electrical life compared to air or oil circuit breakers.
Are these breakers weatherproof?
Yes. Our breakers are IP55-rated and resistant to dust, rain, and UV exposure, making them suitable for harsh outdoor conditions.
Can your breakers be SCADA-enabled?
Yes. Our outdoor breakers can be integrated with SCADA, remote switching, and monitoring systems for grid automation.
What safety features are included?
Each breaker includes mechanical interlocks, earth switches, fault indication, and insulation barriers to ensure operator safety.
Do you provide installation and testing?
Yes. From panel design through installation, testing, and commissioning, we provide comprehensive support.
What is the typical delivery time?
2 to 4 weeks, based on the needs for customization and configuration.
Can your 33 kV breaker handle high fault levels?
Absolutely. Our breakers are available in 25kA and 31.5kA fault current ratings, suitable for high short-circuit environments.
