📘 Understanding IEC 61439-1 & IEC 61439-2: The Backbone of LV Switchgear Design
If you work with Low Voltage (LV) switchgear and controlgear assemblies, you’ve likely heard of . But do you know the difference between Part 1 and Part 2?
✅ Safety First: Ensures proper thermal withstand, insulation, and temperature rise limits. ✅ Reliability: Guarantees assemblies can handle short-circuit stresses. ✅ Compliance: Mandatory for CE marking and many global certifications.
Together, they define safety, thermal performance & short-circuit withstand for modern LV switchboards.
