MAXGE DC Surge Protection for Electrical Projects
Published October 13, 2026 | Canton Fair in Guangzhou October 15–19, 2026
MAXGE SGS1-40DC is a DC surge protective device (SPD) for transient overvoltage protection. It is a product option for buyers sourcing DC surge protection as part of an electrical project. Share your DC system voltage and protection requirements with our team to discuss the relevant configuration and technical information.

MAXGE SGS1-40DC DC surge protective device
The role of a DC surge protective device
An SPD is specified for transient overvoltage protection. Its selection is considered alongside the other protective devices in the circuit. If your project needs DC circuit breakers as well as SPDs, provide both sets of requirements so that each product can be reviewed for its own function.
For a solar or another DC installation, identify where surge protection is required and the system conditions at that point. This gives the product discussion a defined application rather than relying on a product name alone.
Understand the voltage and surge ratings
MAXGE’s SGS1-DC family information lists a nominal discharge current of 20 kA and a maximum discharge current of up to 40 kA. These surge-discharge ratings describe the SPD’s surge performance. Confirm the voltage, pole configuration and ratings of the exact SGS1-40DC version requested.
| Selection detail | Information to provide |
| DC system voltage | Operating voltage and the required maximum continuous operating voltage of the SPD |
| Protection configuration | System arrangement, connection requirements and number of poles |
| Surge performance | Required nominal and maximum discharge current, plus voltage protection level |
| Project documentation | Destination country, specified standard and required model documents |
Prepare your SPD inquiry
If a project specification already defines the surge protection requirements, send those values with your inquiry. Where a previous device is being reviewed for replacement, include its complete ratings and the installation requirements so the comparison can be made on technical information.
- Company name, destination country and application.
- DC system voltage, required SPD configuration and protection ratings.
- Any specified standard, technical approval or model documentation.
- Required quantity and purchasing schedule.
Ask for the datasheet matched to the proposed version. If your market requires certification or a declaration of conformity, request the document for the exact model and configuration being considered.
Meet MAXGE to discuss DC protection
Our team will be at the 140th Canton Fair in Guangzhou, October 15–19, 2026, at booths 15.3 C29–30 and D10–11, or 14.3 F23–25. Bring your DC SPD requirements to discuss SGS1-40DC and the other DC protection products relevant to your project.
