MAXGE DC Circuit Breakers for Solar and DC Projects
Published October 13, 2026 | Canton Fair in Guangzhou October 15–19, 2026
DC breaker selection starts with the circuit voltage, current and protection requirements. MAXGE offers EPB-63M-DC miniature circuit breakers and SGM6-630DC molded case circuit breakers for buyers evaluating DC protection. If you are sourcing for a solar or another DC project, share the system details so our team can discuss the appropriate product version.
Share the DC system voltage, circuit current, pole requirements and application. Request DC breaker details

Compare DC miniature and molded case breakers
| Product | Product type | Published sample information |
| EPB-63M-DC | DC miniature circuit breaker | 1–63 A current options; 1-pole to 4-pole configurations |
| SGM6-630DC | DC molded case circuit breaker | Dedicated sample covers a 2-pole, 1500 V DC configuration with 250–630 A current options |
These sample figures describe the covered product versions. The usable voltage, pole arrangement and breaking capacity must be checked together for the exact configuration being considered.
EPB miniature DC breaker options
EPB-63M-DC provides a miniature breaker format for circuits within the ratings of its selected version. Its dedicated sample lists rated-current options from 1 A to 63 A and configurations from one to four poles. When requesting information, state the DC voltage as well as the circuit current so the relevant pole arrangement and technical ratings can be reviewed.
SGM molded case DC breaker options
For buyers reviewing SGM6-630DC, its dedicated product sample provides a specific reference: a 2-pole configuration at 1500 V DC, with rated-current choices of 250, 320, 400, 450, 500 and 630 A. At 1500 V DC, the sample lists Icu and Ics of 20 kA (T = 10 ms). Use this combination as a defined sample specification when discussing the corresponding version with MAXGE.
Prepare the system details for a technical review
A solar or DC project can have several circuit conditions within one installation. Identify the particular circuit where the breaker will be used and provide the voltage and current for that circuit. A single-line diagram or a written specification helps connect the product discussion to your installation requirements.
- Application and maximum DC operating voltage of the circuit.
- Rated current, pole configuration and specified connection arrangement.
- Required short-circuit breaking capacity and protection characteristics.
- Installation space, operating environment and accessory requirements.
- Destination country, required product documentation and quantity.
DC circuit breakers provide a different protection function from DC surge protective devices. If the project also requires protection against transient overvoltage, include that requirement in the discussion so the breaker and surge protection selections can be reviewed as separate items.
Discuss DC protection at Canton Fair
Meet MAXGE at the 140th Canton Fair in Guangzhou, October 15–19, 2026. Visit booths 15.3 C29–30 and D10–11, or 14.3 F23–25, to discuss EPB-63M-DC, SGM6-630DC and your DC protection requirements.
Send your circuit requirements through our website inquiry form. Email: market@maxge.com. Discuss your DC breaker application
