## Long description

The BEMKO A52-SPD-GDT-DC-3P-T2 is a professional 3-pole DC surge protection device engineered for 1000V electrical systems. Classified as a Type 2 protector, this unit incorporates an advanced gas discharge tube (GDT) technology to provide robust defense against transient overvoltages. By effectively diverting excess energy caused by lightning strikes or switching operations, it safeguards sensitive components within photovoltaic installations and industrial DC circuits, maintaining system integrity and operational longevity.
Advantages
This surge protection device offers superior reliability through its specialized gas discharge tube design, which ensures a stable response to voltage spikes. Its 3-pole configuration is specifically optimized for high-voltage DC applications, providing comprehensive protection across multiple lines. The Type 2 classification makes it an ideal choice for secondary protection, effectively reducing residual voltage levels to safe limits for connected equipment. Its durable construction ensures consistent performance in demanding electrical environments, minimizing the risk of downtime and costly hardware damage.
Suitable for
Photovoltaic solar power systems
Industrial DC power distribution networks
Protection of DC-side inverter components
General 1000V DC electrical installations
When it may not be suitable
This device is not intended for AC electrical systems and should not be installed in circuits exceeding its rated voltage of 1000V DC. It is also not a substitute for primary lightning protection systems in areas with high direct lightning strike exposure, where additional external protection measures are required.
Key specifications
Type: 2
Poles: 3
Maximum operating voltage: 1000V DC
Technology: Gas Discharge Tube (GDT)
Application: DC circuits
How to use
The device is designed for mounting on a standard DIN rail within an electrical distribution board. Installation must be performed by a qualified electrician in accordance with local electrical codes. The device should be connected in parallel with the DC circuit being protected, ensuring that the input and output terminals are correctly identified. Proper grounding is essential for the device to function effectively, so ensure the earth connection is secure and has low impedance.
What to consider before purchase
Verify that your system voltage does not exceed 1000V DC.
Ensure there is sufficient space on the DIN rail within your enclosure.
Confirm that the device is compatible with your specific DC circuit configuration.
Check local regulations regarding the mandatory use of surge protection in your region.
Usage recommendations
Regularly inspect the status indicator on the device to ensure it remains in an operational state. If the indicator shows that the protection module has reached its end of life, replace the unit immediately to maintain continuous system safety.
