6. Suitable for three phase 380V/400V AC system compatible.
Surge Protection Device for Electrical Panel is designed to control transient overvoltage entering distribution panels. Installed inside or adjacent to the panel, it limits surge energy before it reaches breakers, branch circuits, and connected electrical loads. The device remains active during normal power distribution and does not interfere with panel operation. It supports protection of internal wiring, breakers, and panel-fed equipment during lightning activity or power switching conditions. By managing abnormal voltage at the panel level, it helps maintain stable electrical conditions across connected circuits and panel-based power systems.
Features
1. Panel-Level Surge Limiting: Controls transient voltage directly at the electrical panel entry point.2. Fast Electrical Response: Reacts promptly when abnormal overvoltage conditions occur.
3. Breaker and Circuit Coverage: Limits surge exposure before it reaches branch circuits and loads.
4. Defined Voltage Control Range: Keeps incoming voltage within preset electrical thresholds.
5. Panel-Compatible Structure: Fits standard electrical panels without layout changes.
6. Continuous Operating State: Remains active during routine power distribution.
Advantages
1. Circuit Load Protection: Reduces voltage-related stress on connected circuits and devices.2. Wiring Impact Reduction: Limits surge influence on internal panel wiring and terminals.
3. Distribution-Level Voltage Control: Manages abnormal voltage at the panel distribution point.
4. Centralized Panel Protection: Covers multiple circuits through a single panel installation.
5. Suitable for Repeated Surge Events: Supports environments with ongoing voltage disturbance.
6. Simple Panel Integration: Installs without affecting existing breaker operation.
Applications
1. Electrical Distribution Panels: Core surge control inside panel systems.2. Residential Breaker Panels: Protects household circuits from voltage spikes.
3. Commercial Load Centers: Suitable for building electrical panels and service entrances.
4. Industrial Control Panels: Supports protection for panel-fed control equipment.
5. Power Entry Distribution Points: Applied where supply lines enter panel systems.
6. Electrical System Upgrades: Adds surge control during panel replacement projects.
