FAQ Section
Q: What’s the difference between earthing switch vs disconnector?
A: While both provide isolation, our earthing switch adds definitive ground connection for maintenance safety.
Q: How often should I inspect this device?
A: Recommend visual checks every 6 months with full dielectric testing every 5 years.
Q: Can it operate at 1500m altitude?
A: Standard models are rated for ≤1000m. Contact us for high-altitude variants.
