ABB SurgePro Type 1 Surge Protective Device SPD

THOMESURGEP by ABB is an externally mounted Type 1 surge protective device that shields home electrical service and sensitive equipment from damaging transient voltage events.

Installing a dedicated surge protective device at the service entrance gives whole-home protection beyond single-outlet strips. The ABB THOMESURGEP SurgePro™ is engineered to meet modern residential code and contractor needs, offering fast installation, visible health status, and high surge-handling capability for new construction or retrofits.

How does this unit protect my home’s electronics?

The THOMESURGEP diverts excessive transient voltage away from your wiring and connected appliances, reducing the risk of damage during lightning strikes, utility switching or other surges. It’s coordinated for the service entrance so downstream devices get a first line of defense before reaching branch circuits.

• 36 kA per phase maximum surge capacity to absorb large transients
• 10 kA nominal discharge rating for standardized performance
• Works with 120/240V and 120/208V systems for typical US residential wiring

Will installation interfere with my existing breaker layout?

No. The SurgePro design mounts externally and does not consume breaker spaces, making it contractor-friendly for both new panels and retrofits. It’s compatible with PowerMark PRO and most other load centers used at service entrances or sub-panels.

• Externally mounted wiring keeps breaker slots free for circuits
• Meant for service-entrance or sub-panel placement per NEC guidance
• Quick installation reduces labor time and panel modifications

How will I know when the SPD needs replacing?

THOMESURGEP includes an LED indicator that clearly shows the unit’s operational status. When the LED signals failure or end-of-life, replacement is straightforward so protection is quickly restored.

• Integrated LED status makes health checks simple and obvious
• Visible indication reduces uncertainty for homeowners and electricians
• Routine inspection ensures continuous surge protection coverage

Is the product code-compliant and suitable for new construction?

Yes. This SPD is designed to comply with NEC 2023 Art. 230.67 surge requirements and provides the surge ratings typically specified for modern residential service entrance protection. It also meets high short-circuit and coordination ratings for safety and reliability.

• NEC 2023 Art. 230.67 compliant for service entrance applications
• 200 kA SCCR supports robust coordination with service equipment
• Operates at 50–60 Hz to cover typical residential power frequencies

Who is this for: ABB THOMESURGEP SurgePro™ is aimed at electricians, builders and homeowners who want certified, contractor-friendly whole-house surge protection. It suits new home builds, renovations, and any residential installation where NEC-compliant, externally mounted Type 1 protection is required. Choose this unit when you need a visible, high-capacity SPD that installs without occupying breaker spaces and is built to ABB’s industrial-quality standards.
