Heschen Universal Rotary Cam Selector Changeover Switch SZW26 20/D202.2 660V 20A ON OFF 3 Position 2 Phase 8 Terminals,TUV

Technical specifications: professional cam selector switch type SZW26-20/D202.2 designed for a rated insulation voltage (Ui) of 660 V and a thermal rated current (Ith) of 20 A according to the strict industrial standard ENIEC 60947-3 TÜV-tested industrial quality: This high-quality component has undergone strict quality and safety tests. The official TÜV and CE certification guarantees you the highest operational safety and unrestricted compliance in professional control cabinet construction 3 switching positions with zero position: design with 3 unique switching positions (1-0-2). The central zero setting (0) works as a safe off level, ensuring absolute physical disconnection when switching between two power sources or systems 2-pole symmetric switch: Equipped with 8 robust screw terminals, this rotary switch switches two poles absolutely synchronously. In position 1, the contacts 1-2 and 5-6 close while position 2 closes the contacts 3-4 & 7-8 simultaneously Perfect for single-phase mains switching: ideal for switching both the phase (L) and the neutral conductor (N) in AC networks (e.g. small emergency power generators, solar systems or measuring points), safely and without contact overlap
