₦25,650.00
The Suntree 1500V 25A DC Isolator Switch is an essential protection component used in modern solar power systems and high voltage DC distribution circuits. Designed to provide safe manual disconnection of photovoltaic array voltage, it ensures the safety of inverter equipment and maintenance personnel during installation, servicing, and emergency shutdown operations.
This isolator switch supports a rated voltage of up to 1500V DC and a rated current capacity of 25A. It is ideally suited for large-scale solar installations where higher system voltage improves efficiency and reduces cable losses across long PV string layouts.
The switch delivers fast disconnection performance with a switching response time of approximately 3 milliseconds. This rapid interruption helps protect inverter equipment and ensures the safety of maintenance personnel during servicing operations.
Its modular DIN rail mounting structure allows flexible installation inside solar combiner boxes, inverter protection panels, and DC distribution enclosures. The switch supports both two-pole and four-pole configurations to accommodate different system wiring requirements.
Manufactured using high-durability insulation materials, the isolator is designed to operate reliably in demanding outdoor solar environments. It supports an operating temperature range from -40°C to +85°C, ensuring stable performance across varying climate conditions.
The device complies with IEC60947-3 international switching standards and supports photovoltaic application category DC-21B operation for safe DC load interruption performance. This compliance ensures reliable operation and adherence to global safety requirements.
Its non-polarity design allows flexible cable connection during installation without the risk of reverse wiring errors. This simplifies installer workflow and improves installation safety consistency across solar panel arrays.
