Orlando Surge Protection
Square D Surgelogic surge protective devices (SPDs) are designed to limit transient over voltage and divert surge current away from connected equipment. A coordinated design can place protection at the service entrance, distribution equipment and sensitive loads.
Central Florida gets hit harder by lightning than anywhere else in the country, which makes Orlando surge protection a design requirement rather than an upgrade.

Florida Building Code
Florida Building Code articles 449.3.15.6 and 450.3.19.5 require exterior electrical circuits to be surge protected with a dedicated SPD. That is a Florida specific requirement that catches out of state design teams regularly.
The ASCO Model 459 Exterior Circuit Surge Protection Hub was designed specifically to simplify that compliance. It is a surge protected tap box that follows proven NEC 314.28 wiring practices, so you get safe, secure circuit connections while satisfying the Florida requirement in one assembly.
If you are building in Central Florida, get this into the design early. It is a lot cheaper than discovering it at inspection.
Cascaded protection
One device at the service entrance is a start. Real protection is layered, because each stage knocks the surge down for the next one.
Surgelogic EMA, EMB and EMD devices deliver specification grade performance at the service entrance in UL/NEMA 1, 4 and 4X enclosures, with the EMD including a disconnector switch as standard.
Surgelogic HWA, HWB and HWC devices for distribution and critical branch panels, with EMI and RFI noise attenuation as a standard feature on the HWA.
Compact, point-of-use surge protective devices fit easily adjacent to power panels or directly on sensitive equipment, adding a critical layer of defense to a cascaded system.
The ASCO Model 459 hub protects exterior circuits with dedicated SPDs to satisfy Florida Building Code articles 449.3.15.6 and 450.3.19.5.
Advanced protection for Square D NQ panelboards that installs in two minutes or less, against roughly twenty minutes for a typical externally mounted SPD.
Surgelogic Surgebreaker Plus and QO or Homeline plug-on neutral SPDs give residential customers all in one protection for appliances, lighting and electronics.

Compare a fully layered design against a single service entrance device, then simulate a strike and watch what actually reaches your equipment.
Watch how much of the transient actually reaches your equipment when protection is layered, against what happens when a single device at the service entrance is expected to do all of the work.
We keep commercial and residential SPDs in stock. The full device range is documented in Schneider Electric’s surge protection catalog.

The United States recorded 252 million lightning events in 2025, a 20 percent increase on 2024 and an eight year high. Florida leads the country on density by a wide margin, and that is the environment every panel, control system and piece of connected equipment in Central Florida has to survive.

Prepare for Storm Season
During storm season, a whole-home surge protection system helps defend appliances, electronics and essential home systems from power surges caused by lightning and utility disruptions. We can help you choose the right protection for your electrical panel and create a more complete, layered defense throughout your home.
Frequently asked
In simple terms, a UL 1449 Type 1 device can be installed on the line side of the service disconnect, and a Type 2 device is installed on the load side. Surgelogic EMA, EMB, EMD and HWB are Type 1 listed, while HWA, HWC and HWG are Type 2 listed, several with complementary UL 1283 listings for EMI and RFI noise attenuation.
Usually yes. Surge protection works best cascaded: a device at the service entrance knocks the surge down, distribution panel devices reduce it further, and equipment level devices handle what is left. A single service entrance device on its own leaves sensitive equipment more exposed than most people expect.
We stock commercial and residential Square D Surgelogic products at our Orlando counter and source the rest through the CED network. Call (407) 422-9841 and we will tell you what is on the shelf today.
Yes. Surgelogic Surgebreaker Plus provides all in one whole house protection for appliances, lighting, cable, ethernet and telephone, and the QO and Homeline plug-on neutral SPDs install as easily as a circuit breaker in a compatible load center.
