The Voltage Surge Suppressor provides reliable lightning and overvoltage protection, featuring a high-capacity 20 kA (8/20 µs) discharge capability. Its compact two-pole structure allows flexible installation across a wide range of environments, while the modular repair design enables quick and convenient maintenance with minimal impact on system operation. Integrated operational status indicators deliver real-time condition feedback, helping operators monitor performance efficiently and improve overall productivity.
Protection Performance
1. High Surge Discharge Capacity: Provides reliable protection against lightning and transient overvoltage events with a 20 kA (8/20 µs) discharge capability, ensuring stable system operation.2. Effective Overvoltage Suppression: Limits surge voltage to safe levels, reducing the risk of damage to sensitive low-voltage equipment.
3. Protection for LPZ 0B–1 and Higher Zones: Designed for installation at LPZ 0B–1 or higher locations to enhance overall system surge protection coordination.
4. Class II (Class C) SPD Performance: The Voltage Surge Suppressor operates as a modular Class II solution, suitable for downstream protection in low-voltage power distribution systems.
5. Fast Response to Transient Surges: Reacts quickly to sudden surge currents to minimize energy transfer and improve equipment safety.
6. Stable Protection Under Repeated Surges: Maintains consistent protection performance even under multiple surge events, supporting long-term system reliability.
Key Features
1. MOV Clamping Network: Absorbs surge energy and limits peak voltage during transient events.2. Thermal Disconnect Protection: Opens the circuit when the module reaches abnormal temperature conditions.
3. LED Status Indication: Shows protection state at a glance for quick on-site checks.
4. Remote Alarm Contacts: Provides dry contact output for alarm panels and monitoring inputs.
5. DIN-Rail Or Panel Mount Housing: Fits standard cabinet layouts with compact width and tidy wiring paths.
6. Finger-Safe Terminals: Supports safer installation with guarded terminals and clear marking.
Advantages
1. Fewer Control Resets: Helps prevent PLC reboots and nuisance trips caused by surge bursts.2. Lower Repair Spend: Shields I/O cards, power supplies, and drives from high-stress voltage spikes.
3. Faster Fault Finding: Visible indicators and alarm outputs speed troubleshooting and routine checks.
4. Shorter Service Time: Plug-in module designs support quick replacement without rewiring terminals.
5. Safer End-Of-Life Behavior: Thermal disconnection reduces overheating risk when the device is worn out.
6. More Stable Site Power Quality: Supports multi-point surge protection plans across cabinets and field circuits.
Applications
