Product Description
Industrial-grade Type 2 SPD fits 385Vac three-phase factory distribution cabinets for LPZ0B-LPZ1 zones, delivering surge protection for factory automation, EV charger auxiliary power and lab precision instruments. It carries 20kA nominal discharge current and 40kA maximum surge capacity with ≤25ns response time to clamp transient high voltage instantly. Pluggable modules simplify maintenance replacement, anti-vibration construction withstands production line vibration, and V0 flame retardant housing enhances cabinet safety. Dual monitoring via front status window and remote signalling contacts, certified TUV & CE for global industrial export projects.
Key Features
385Vac continuous withstand voltage adapts fluctuating industrial mains
Low residual voltage ≤1.8kV to reduce electronic breakdown risks
Built-in thermal release automatically disconnects during component failure
Plug-in modular design allows quick on-site replacement
TUV & CE dual certification for overseas industrial engineering projects
