The SRD-30 is designed to protect photovoltaic strings from fault conditions by interrupting excessive current caused by overloads or short circuits.
The SRD-30 uses a plug-in fuse design that allows the fusible core to be replaced quickly. This design can simplify maintenance and reduce downtime during fuse replacement.
The fuse holder is manufactured using PA66 flame-retardant material. The integrated indicator window provides a visual indication of fuse status: the indicator light turns on when the fuse core has blown.
The product also incorporates a busbar design intended to provide reliable and organized wiring within photovoltaic protection systems.
One of the practical features of the SRD-30 is its built-in fuse status indicator window.
| Fuse Condition | Indicator Status |
| Fuse Normal | Indicator Off |
| Fuse Blown | Indicator On |
This visual indication allows technicians to identify a blown fuse more easily during inspection and maintenance.
The SRD-30 uses a 1P configuration and accommodates a φ10 × 38mm fuse. Its busbar-oriented design is intended to provide clean and reliable wiring in PV distribution and string protection applications.
The fuse should be selected according to the electrical characteristics of the protected PV string and installed in accordance with the applicable electrical installation requirements.
The SUNTREE SRD-30 is a 1100V DC photovoltaic fuse designed to protect PV strings against overload and short-circuit conditions.
The SRD-30 has a rated service voltage of 1100V DC and a rated insulation voltage of 1200V.
The SRD-30 supports fuse current ratings from 1A to 30A within the same current frame. The fuse holder itself has a rated service current of 63A.
The Technical Reference specifies a rated limiting short-circuit current of 30kA.
The SUNTREE SRD-30 is a thermal DC fuse designed specifically for low-voltage solar PV applications.
