Description

The GSP10-C40N AC Surge Protection Device (SPD) is a high-performance Type 2 (T2) overvoltage protector specifically designed for AC power supply networks. Installed between the power grid and your electrical equipment, this SPD effectively drains, suppresses, and reduces overcurrent and overvoltage caused by induced lightning strikes or power grid fluctuations. Featuring a robust High Energy MOV core, the GSP10-C40N ensures maximum reliability and significantly reduces the risk of damage to sensitive electrical devices.

Optimized for AC Distribution Systems

Perfectly suited for installation in sub-distribution cabinets, JP cabinets, and other critical AC power nodes. Compatible with TN-S, TN-C, and TT network systems, the device offers a rapid response time of less than 25ns. This ensures immediate suppression of power surges, providing comprehensive L-PE, N-PE, and L-N protection modes to safeguard your entire electrical infrastructure.

Key Features & Advantages

  • Heavy-Duty Protection: Handles a nominal discharge current (In) of 20kA and a maximum discharge current (Imax) of 40kA, providing a robust primary defense line.
  • Integrated Remote Monitoring: Built-in remote communication connections (14 11:NO, 11 12:NC) allow for seamless integration into smart building management 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.
  • Standardized Installation: 35mm DIN-rail mounting design (EN60715) enables quick, secure, and standardized installation in any standard electrical cabinet

Frequently Asked Questions (FAQs)

1. What is the GSP10-C40N?

The GSP10-C40N is a Type 2 (T2) AC Surge Protective Device (SPD) designed to be installed between the power supply network and electrical equipment. It acts as a critical safety component in AC power systems.

2. What functions does it provide?

It provides essential protection by rapidly draining, suppressing, and reducing overcurrent and overvoltage caused by induced lightning strikes or power grid fluctuations. This prevents severe damage to electrical equipment and ensures system stability.

3. What are the key parameters for selection?

When selecting this SPD, the critical parameters to consider are the AC Maximum Continuous Operating Voltage (Uc), Nominal Discharge Current (In = 20kA), Maximum Discharge Current (Imax = 40kA), and the Protection Level (Up). Ensure these match your AC network specifications (TN-S, TN-C, TT).

4. What options are currently available?

The GSP10-C40N series offers varying Maximum Continuous Operating Voltage (Uc) options (275V, 320V, and 385V variants) to suit different AC voltage requirements. It also comes standard with remote communication contacts (14 11:NO, 11 12:NC) for smart monitoring.

5. What standards does it comply with, and which markets is it designed for?

This device is designed for global markets and strictly complies with major international standards, including Chinese Standard GB/T 18802.11-2020, IEC 61643-11: 2011, and EN 61643-11: 2012. It is fully TUV and CE certified.

6. What are the installation precautions?

The SPD should be mounted on a standard 35mm DIN rail (EN60715) inside a sub-distribution cabinet or JP cabinet. Use a recommended cable cross-section of ≥ 10mm² (4-16 mm² supported). Ensure terminal screws are tightened to the correct torque (Upper: 1.2Nm, Bottom: 2.0Nm) and proper wire insertion lengths (Upper: 12mm, Bottom: 15mm) are observed for a secure connection.
