Selection Criteria
Voltage & Current Ratings
You must match the voltage and current ratings to your solar system. Solar PV systems use higher DC voltages than AC circuits. Most homes and businesses need breakers rated for 300V, 600V, 900V, or up to 1200V DC. The current ratings are usually between 1A and 63A. This depends on how big your system is and how much power it uses.
| Parameter | Range/Values | Notes |
|---|---|---|
| Rated Current (A) | 1A, 2A, 3A, 4A, 6A, 10A, 16A, 20A, 25A, 32A, 40A, 50A, 63A | These are common current ratings for DC MCBs in solar setups. |
| Rated Operating Voltage | DC300V, DC600V, DC900V, DC1200V (max) | These are typical voltage ratings for solar PV systems at home or work. |
| Pole Configurations | 1P, 2P, 3P, 4P | These support different system setups, from single-phase to three-phase. |
| Breaking Capacity | 6kA, 10kA | These are good for stopping fault currents in solar DC circuits. |
ONESTOP gives you many voltage and current choices. You can pick a breaker that fits your needs.
Breaking Capacity
Breaking capacity shows how much fault current the breaker can stop. Solar systems often need a breaking capacity from 2 kA to 10 kA. This depends on the voltage and pole setup. A higher breaking capacity means better protection from short circuits. ONESTOP’s DC MCBs meet or beat these standards. This helps you feel safe.
Certifications
Certifications show your breaker meets safety and quality rules. Look for marks like IEC, CE, UL 489, and UL 1077. These mean the breaker passed hard tests for solar use. ONESTOP’s breakers have all the big certifications. You know you are buying a safe and trusted product.
Tip: Always look for certifications before you buy a DC MCB for your solar project.

How to Choose
Step-by-Step Guide
Picking the right DC miniature circuit breaker for your solar system takes careful steps. You want to keep your system safe and protect your money. Follow these steps to help you choose:
- Calculate Your Load Current
Add up the current from every device in your solar system. This tells you the lowest rating your breaker should have. - Determine Breaker Size
Take the inverter’s biggest output current and multiply by 1.25. This makes sure the breaker can handle extra power. Pick the next highest standard breaker size. - Match Voltage Rating
Find out your system’s highest DC voltage. Choose a breaker with a rating at or above this number. Common choices are 600V, 1000V, or 1500V DC. Sometimes, you need to connect poles together for higher voltages. - Select Breaking Capacity
Make sure the breaker can stop the largest fault current in your system. This helps prevent damage and fire. - Choose the Right Type
Pick an MCB type (B, C, or D) that fits your load. For solar PV, type C or D is usually best. - Consider Environmental Conditions
Look at where you will put the breaker. Pick one with the right IP rating for dust, water, and heat. - Check Certifications
Always pick breakers with certifications like IEC 60947-2, UL 508, or UL 1741. These breakers have passed tough safety tests.
Tip: Always follow what the manufacturer says for sizing and installation. Use MCBs made for DC to make sure your system works well.
Common Mistakes
Many people make mistakes when picking DC miniature circuit breakers for solar systems. You can avoid these problems by learning what to watch for:
- Not matching the breaker’s voltage rating to your system can hurt parts and make them wear out faster.
- Forgetting about temperature can make breakers trip early or stop working. Always pick breakers that work well in high heat.
- Picking the wrong size can cause too many trips or not enough protection. Small breakers trip too much. Big breakers may not keep your system safe.
- Not checking for certifications and standards can make your system less safe. Certified breakers lower risks by up to 40%.
- Ignoring things like humidity and heat can make breakers not last as long or work poorly.
