## Summary description

The BEMKO A52-SPD-GDT-DC-3P-T1T2 is a 3-pole surge protection device designed for DC systems up to 1000V. Featuring T1+T2 class protection and an integrated gas discharge tube, it provides reliable protection against lightning and switching surges. Ideal for photovoltaic installations, this device ensures safety and longevity for sensitive electrical equipment by diverting excess energy to the ground.

## Long description

The BEMKO A52-SPD-GDT-DC-3P-T1T2 is a high-performance 3-pole surge protection device engineered specifically for direct current (DC) systems operating up to 1000V. By combining T1+T2 class protection with an integrated gas discharge tube, this device offers a robust defense against both direct lightning strikes and transient switching surges. It is designed to safeguard sensitive electrical components in photovoltaic installations by effectively diverting dangerous energy spikes to the ground, thereby maintaining system integrity and extending the operational lifespan of connected hardware.
Advantages
This surge protection device stands out due to its dual-class T1+T2 protection, which provides comprehensive coverage against high-energy surges and finer voltage transients. The inclusion of a gas discharge tube technology ensures a stable and reliable response to electrical disturbances. Its 3-pole configuration is optimized for DC circuits, offering a compact and efficient solution for modern renewable energy setups. The device is built to withstand demanding environmental conditions, ensuring consistent performance and safety for critical infrastructure.
Suitable for
Photovoltaic solar power systems
DC power distribution networks
Protection of inverters and charge controllers
Industrial DC electrical installations
This device may not be suitable for AC power systems, as it is specifically engineered for DC voltage applications. It is also not intended for use in circuits exceeding the rated 1000V DC threshold, as this could lead to equipment failure or safety hazards.
Key specifications
Type: T1+T2 surge protection device
Poles: 3-pole
Maximum operating voltage: 1000V DC
Technology: Gas discharge tube
Discharge current: 12.5kA
Installation should be performed by a qualified electrician in accordance with local electrical codes. The device is typically mounted on a standard DIN rail within a distribution board. Ensure that the grounding connection is secure and has low impedance to allow for the effective dissipation of surge energy. Regularly inspect the status indicator to verify that the protection module is functioning correctly.
What to consider before purchase
Verify that your system voltage does not exceed 1000V DC
Ensure compatibility with your existing DIN rail mounting system
Confirm the required discharge capacity for your specific installation site
Check local regulations regarding lightning protection requirements
For optimal performance, ensure the device is installed as close as possible to the equipment it is intended to protect and maintain a short, direct path to the grounding system.
