IEC vs GB Standards for Vacuum Contactors: The Ultimate Engineering Guide | XBRELE Tech Talk

Don’t let the "invisible" spec cause a failure in your switchgear. ⚡️ In this audio deep dive, we break down the critical differences between IEC (International) and GB (Chinese National) standards for Vacuum Contactors.

Whether you are designing for a stable grid in Frankfurt or a high-altitude mine in Tibet, choosing the wrong standard can lead to dielectric failure or insurance nightmares.

Based on XBRELE's engineering documentation, this discussion covers: ✅ Why "IEC compliant" isn't enough for high-altitude regions. ✅ The physics of failure: Thermal stress, dielectric resilience, and mechanical fatigue. ✅ Material Science: How CuCr contact composition changes between our CKG (IEC) and LCZ (GB) series. ✅ How to specify the right contactor for your project (Sample RFQ templates included).
