ABB THOMESURGE Residential Surge Protective Device is a wired residential SPD designed to help protect compatible 120/240V electrical systems from transient surge events.
Small details.
Big decisions.
Look beyond the product name. These four checks help narrow the right configuration.
MISSION.A little precision. A smarter selection.
Wired Surge Protection
THOMESURGE is a wired residential surge protective device. Match the installation and conductor routing to the approved distribution equipment.
120/240V AC System
This two-pole device is intended for compatible 120/240V AC systems. Confirm the supply configuration before selecting the SPD.
36 kA Maximum Surge Current
The listed maximum surge-current rating is 36 kA. Compare this figure with the same rating type when evaluating surge devices.
10 kA Nominal Surge Current
The nominal surge-current rating is 10 kA. This surge-performance value is different from a branch-circuit ampere rating.
Before you select
Match the equipment. Check the fit.Electrical System
Match the SPD to the 120/240V AC system and approved equipment. Confirm the connection arrangement for the selected catalog number.
Surge Ratings
Compare nominal and maximum surge-current ratings using their correct definitions. These are not branch-circuit ampere ratings.
Connection & Location
Review the manufacturer’s installation location, conductor routing and protective-device requirements for the complete system.

Important Product Questions
Does an SPD replace the circuit breaker?
No. Surge protection and circuit overcurrent protection serve different functions. Use the SPD with the required equipment and protective devices.
Are nominal and maximum surge-current ratings the same?
No. They describe different surge-performance ratings. Compare the same rating type when evaluating devices and confirm the selected model’s values.
What must match before replacing an existing surge device?
Confirm system voltage, equipment compatibility, SPD type, connection method and installation requirements. Physical fit alone is not sufficient.
Important Model Distinction
Surge-current ratings, connection method and approved installation depend on the SPD catalog number. Surge protection does not replace the system’s required circuit protection.
