How to Select the Right Surge Protective Device
When choosing a surge protective device, consider:
- Type – Type 1 for direct lightning, Type 2 for general protection, and Type 3 for terminal devices.
- Surge capacity (Imax & In) – match the protection level to your environment (20kA/40kA for medium-level, higher for industrial-heavy zones).
- Number of poles – select 2P, 3P, or 4P depending on system configuration.
- Standards & certification – ensure compliance with IEC 61643-11 and EN standards.
- Safety materials – flame-retardant housing for improved fire resistance.
- Brand reliability – choose manufacturers with proven expertise in surge protection.
The G2040MT-280-4P meets these requirements, making it a trusted Type 2 SPD for three-phase distribution networks.
