Features
1. Green light indicates normal and red light indicates fault for operation.
2. Bulit-in circuit breaker, and thermal disconnection device, when the fault occurred, the thermal disconnection device will cut off the SPD from the power net, the green window will change.
3. External wiring terminal, easy for connection, suitable for indoor application.
4. To have a double protection,we also included a circuit breaker 32A pin1,2, the electrician installating this unit should make sure that the close circuit available supply will be able to trip this Breaker if & when the SPD developed a short circuit or overload, other wise the electrician must change the Breaker into a smaller value to satisfy to above..
5. Suitable for TT/ TN installations.
6. Suitable for single phase 220V-240V(50/60 Hz)AC power supply system.
Sub-Distribution Boards
Single Phase, TT/TN
L-N; N-PE
In=20kA/40kA(8/20μs)
Imax=40/65kA(8/20μs)
Circuit Breaker Surge Protection is designed to control transient voltage within electrical breaker panels. Installed alongside or integrated with circuit breakers, it limits surge energy before it reaches branch circuits and connected loads. The device remains active during normal power flow and does not interfere with breaker operation. It supports stable electrical conditions during lightning activity or grid switching events. Suitable for residential and commercial panels, this product helps reduce electrical stress on wiring and devices by managing abnormal voltage levels directly at the distribution point.
Features
1. Breaker Panel Surge Control: Limits voltage spikes directly inside circuit breaker panels.2. Fast Electrical Reaction: Responds quickly when abnormal voltage conditions appear.
3. Branch Circuit Coverage: Controls surge exposure before it spreads to downstream circuits.
4. Defined Voltage Limiting Range: Keeps voltage within preset electrical thresholds.
5. Panel-Compatible Structure: Fits standard breaker enclosures without layout changes.
6. Continuous Operating State: Remains active during normal electrical distribution.
Advantages
1. Circuit Load Protection: Reduces voltage stress on connected branch circuits.2. Wiring Impact Reduction: Limits surge-related influence on internal cables and terminals.
3. Panel-Level Voltage Control: Manages abnormal voltage directly at the distribution point.
4. Centralized Electrical Defense: Covers multiple circuits through one protection location.
5. Long-Term Panel Use: Suitable for repeated transient voltage exposure over time.
6. Simple Panel Integration: Installs without affecting existing breaker functions.
Applications
1. Residential Breaker Panels: Surge control for household electrical distribution systems.2. Commercial Distribution Boards: Suitable for building power panels and load centers.
3. Branch Circuit Protection: Helps guard lighting, outlet, and equipment circuits.
4. Electrical System Upgrades: Adds surge control during panel replacement projects.
5. Equipment Protection Circuits: Supports panels supplying sensitive electrical devices.
6. Power Entry Distribution Points: Applies where power is divided into multiple circuits.
