 Product Information
1.1 The enclosure is completely formed by Al-Zn coated steel plate after multiple bending processed by CNC machine, then is asse mbled with the bolts, which has strong mechanical strength and effectively ensure the neatness and good appearance. The door is painted by the plastic powder and has strong anti-impact and corrosion proof ability. The protection grade of enclosure is IP4X. 1.2 The main circuit breaker is VHY1-40.5 model Solid-sealed Vacuum Circuit Breaker, which is independently designed and developed by HEAG group.
