Why Choose YRO DC Disconnect Switch?
Designed for Reliable DC Switching Performance
Unlike AC circuits, DC circuits are more difficult to interrupt because the electrical arc does not naturally extinguish at every cycle. YRO DC Disconnect Switches are designed specifically for photovoltaic DC applications and comply with IEC 60947-3, providing reliable manual isolation for systems up to 600V DC.
Each switch is tested before shipment to help ensure stable switching performance in solar installations.
In-House Manufacturing for Better Quality Control
YRO controls key production processes in-house, including plastic injection molding, component assembly, and product testing.
This manufacturing model helps us:
- Maintain consistent product quality across production batches
- Reduce production lead times
- Support OEM and customized orders more efficiently
- Respond quickly to customer design changes
For distributors and equipment manufacturers, this means more stable supply and better production consistency.
Built for Outdoor Solar Installations
Solar disconnect switches are often installed on rooftops, inverter stations, or outdoor electrical cabinets where they are exposed to sunlight, rain, dust, and temperature changes.
YRO DC Isolator Switches feature:
- IP66 protection against water and dust
- UV-resistant enclosure materials for long-term outdoor use
- Corrosion-resistant components suitable for demanding environments
- Wide operating temperature range for different climate conditions
These features make them suitable for residential, commercial, and industrial photovoltaic systems.
OEM and Private Label Support
Many distributors require products that match their own brand and market requirements.
YRO supports a wide range of OEM services, including:
- Company logo printing
- Customized product labels
- Packaging design
- User manuals
- Product configuration customization
Our engineering team also provides technical support during product selection and project development.

Preguntas frecuentes
Q1: What does Top In Top Out mean in a DC isolator switch?
Top In Top Out means the cable entry and cable exit are located at the top side of the switch, creating a simplified wiring arrangement.
Q2: Is a 600V DC isolator suitable for rooftop solar systems?
Sí.
Many residential and small commercial PV systems operate within this voltage range, making 600V DC isolators suitable for these applications.
Q3: Can this switch be installed near the inverter?
Sí.
It is commonly used as a manual DC disconnect point between the PV array and the inverter for maintenance and servicing.
Q4: How do I choose between 600V and 1000V?
Choose the voltage rating based on the maximum DC voltage of your solar PV system.
- 600V DC isolator switchesare commonly used in residential and small commercial solar systems with lower system voltages.
- 1000V DC isolator switchesare designed for larger commercial and industrial PV installations that operate at higher DC voltages.
The isolator switch should always have a voltage rating equal to or higher than the maximum system voltage. Selecting the correct rating helps ensure safe operation, reliable isolation, and compliance with electrical standards.
