How buyers should specify solar DC protection before RFQ
Solar DC protection includes breakers, MCCBs, isolators, surge protection, fuse holders, gPV fuses and rapid shutdown devices. These products should be selected by DC voltage, current, breaking capacity and system architecture.
The safest RFQ defines the circuit role first: string protection, combiner protection, inverter input isolation or surge protection. Then the rating, pole count, enclosure and standard can be confirmed.
- Confirm 600V, 1000V or 1500V DC system rating before choosing device family.
- Match rated current, pole count and breaking capacity to the circuit, not only the cable size.
- Select SPD type and voltage level according to grounding arrangement and protection design.
- Check whether the device will be supplied loose or assembled inside a combiner/distribution box.
- AC breakers cannot be substituted for DC PV circuits unless specifically rated for that DC application.
- Breaking capacity and DC arc performance are often more important than nominal current alone.
- SPD voltage and type must fit the PV array and earthing design.
- Fuse holder, fuse link and cable terminal temperature ratings should be reviewed together.
Open the right family page with the right questions.
DC Isolator Switch
Provides safe DC isolation for inverter input, combiner output or maintenance circuits.
Open when the project needs rotary or switch-style DC isolation.
PV Fuse / Fuse Holder
Protects PV strings with gPV fuse links and matching fuse holders.
Open when string fuse rating, holder size or combiner box fuse layout is required.
Rapid Shutdown Device
Supports module/string-level shutdown requirements for selected markets.
Open when rapid shutdown compliance or rooftop safety rules are part of the RFQ.
DC MCB
Provides compact DC circuit protection for PV and storage circuits.
Open when smaller current ratings and DIN rail mounting are needed.
MCB / Circuit Breaker
MCB / Circuit Breaker options grouped from supplier product families and variant SKUs.
DC MCCB
Provides higher-current molded-case DC protection for combiner or inverter circuits.
Open when higher breaking capacity or larger current rating is needed.
MCCB
MCCB options grouped from supplier product families and variant SKUs.
Surge Protective Device
Protects PV equipment from transient overvoltage on the DC side.

DC Protection sourcing questions
Practical checks buyers usually confirm before quoting, sampling or consolidating a shipment.
Can AC breakers be used on the DC side of a solar system?
No, unless the device is specifically rated for the required DC voltage and breaking capacity. DC arc interruption is different from AC.
What information is needed for DC protection selection?
Provide system voltage, current, pole count, breaking capacity, SPD type, fuse size and whether devices are loose or installed in a box.
How do buyers request a quote for DC Protection?
Send the product list or BOM, quantities, destination country or port, required standards, and target delivery date. OmniSol reviews SKU matching, lead time, packing, and export requirements before quotation.
Can DC Protection be shipped with other solar BOS components?
Yes. OmniSol can review mixed-container feasibility for mounting, cables, connectors, protection devices, combiner boxes, distribution boards, and selected storage accessories.
When are certificates and market documents confirmed?
Document availability is checked at RFQ and order confirmation stage against the selected SKU, supplier, model, and target market requirements.
