Description
High-Performance Type 2 AC Surge Protective Device
GEYA GSP9-C40 and GSP9-D20 T2 AC Surge Protective Devices (SPD) are designed to provide reliable T2 protection for electronic and electrical equipment in buildings vulnerable to lightning overvoltage. Acting as primary protection equipment in main distribution systems, these AC surge protectors ensure the safety and stability of your power grid against unexpected power surges.
Comprehensive Protection for Distribution Systems
Suitable for installation in distribution cabinets, JP cabinets, and other critical nodes, these SPDs are highly adaptable to various network systems including TN-S, TN-C, and TT. By utilizing advanced High Energy MOV (Metal Oxide Varistor) protective elements, the device offers a rapid response time of less than 25ns, effectively mitigating transient overvoltages and extending the lifespan of your electrical infrastructure.
Key Features & Advantages
- Flexible Voltage & Discharge Options: Available in multiple continuous operating voltages (275V, 320V, 385V, 440V). The GSP9-D20 handles up to 20kA (Imax), while the GSP9-C40 provides heavy-duty protection up to 40kA (Imax).
- Versatile Pole Configurations: Offered in a wide range of pole setups (1P, 1+NPE, 2P, 3P, 4P, 3+NPE) to meet specific wiring and phase requirements.
- Remote Monitoring Capability: Built-in remote communication connections (14 11:NO, 11 12:NC) allow for seamless integration into smart building management and monitoring systems.
- Robust & Safe Design: Housed in a UL94 V0 flame-retardant PBT/PA enclosure with IP20 protection, ensuring operational safety in extreme temperatures ranging from -40°C to +70°C.
- Easy Installation: Standard 35mm DIN-rail mounting design enables quick, secure, and standardized installation in any standard electrical cabinet.
