Description

Product Benefits

The GDSC100R-EL32R Solar Isolator Switch is a premium DC disconnect switch designed specifically for modern solar PV systems. Rated up to DC 1200V and 32A, this PV switch-disconnector ensures safe and reliable isolation between solar panels and inverters. Featuring an ultra-fast arcing time of less than 2ms and strict compliance with IEC/EN 60947-3 standards, it is the ideal choice for residential and commercial solar installations requiring robust DC transmission protection.

Application Range

The GDSC100R series PV Switch-disconnector is suitable for power systems with a rated voltage of DC 1200V and below, and a rated current of 32A and below. The product is engineered for infrequent connection and disconnection, effectively isolating the disconnection line and disconnecting 1 to 4 MPPT lines simultaneously. It is highly suitable for isolating lines in DC transmission and distribution systems, such as cutting the direct current circuit between solar panels and inverters safely.

Main Features

  • Compliant with IEC/EN 60947-3 and AS 60947.3 standards.
  • Utilization category: DC-PV1, DC-PV2.
  • Non-polarity design (“+” and “-” polarities can be interchanged).
  • Ingress Protection options: IP20 (Standard) / IP66 (EL Enclosed Version).
  • OFF Lockable mechanism for enhanced maintenance safety.
  • UV resistant and Flammability rated UL94 V-0.
  • Ultra-fast arcing time <2ms.

1. What is the GDSC100R-EL32R?

It is a high-performance PV Switch-disconnector (DC Solar Isolator Switch) designed to safely cut off the direct current circuit between solar panels and solar inverters.

2. What functions does it provide?

It provides reliable electrical isolation and control for infrequent connection and disconnection of DC power lines. It can safely disconnect 1 to 4 MPPT lines at the same time and features a lockable OFF position to protect maintenance personnel.

3. What are the key parameters affecting selection?

When selecting this switch, the critical parameters to consider are the maximum system voltage (up to 1200V DC), the maximum current (up to 32A), the number of poles (4P), and the required ingress protection rating based on your installation environment.

4. What are the currently available options?

The series offers different configurations primarily based on enclosure types. You can choose between standard internal mounting versions (IP20) and enclosed, weather-resistant versions like the EL series (IP66) for outdoor installations.

5. Which standards does it comply with and for which market is it designed?

The switch complies with rigorous international standards including IEC/EN 60947-3 and AS 60947.3. It is designed for global solar markets, particularly meeting the strict safety requirements of European and Australian photovoltaic installations.

6. What are the installation precautions?

The device can be mounted either vertically or horizontally. Ensure the storage and operating environment remains within -40°C to +85°C. While the switch has no polarity, proper cable routing and ensuring the enclosure maintains its IP rating (especially for outdoor IP66 setups) are crucial for long-term safety.
