Why panel-level protection
Protect the electrical system before the surge reaches individual devices
A whole-house SPD is installed at or near the load center so surge energy can be diverted at the panel instead of relying only on plug-in protection at individual outlets.
36,000A surge capacity
A compact protection level designed for everyday residential surge-defense needs.
Protection status at a glance
Front status lights make it easy to check whether the protection system is operating normally.
Simple protection status
Know the protection status without opening the panel
Clear front indicators provide a quick visual check of the SPD's operating status. That matters because a surge protector is only useful when you know it is still ready to protect.
- Easy-to-see front status indicators
- Simple visual inspection during routine electrical checks
- Clear front-panel status visibility
- Compact design for clean panel-area installation
Protect what is connected
Modern homes have more electronics on every circuit
TVs, computers, kitchen appliances, HVAC controls, networking equipment and smart-home devices all depend on the same electrical system. Panel-level surge protection adds a first line of defense for everything downstream.

Key specifications
What matters before you buy
The 36,000A figure is a surge-current rating. It is not the home's service amperage and it is not a substitute for selecting the correct breaker or installation method.

Frequently asked questions
What homeowners usually want to know
What does “36,000 A” mean?
It refers to the SPD's surge-current handling capacity per phase. It does not mean the unit draws 36,000 amps, and it is not the same as your home's electrical-service rating.
Does a whole-house SPD replace plug-in surge strips?
No. Panel-mounted and point-of-use protection can serve different roles. For sensitive electronics, a layered protection approach may still include suitable point-of-use surge protection.
How do I know whether the SPD is operating normally?
The front LED status indicators provide a visual protection-status check. Follow the supplied product instructions if an indicator shows an abnormal condition or is not illuminated as expected.
Can I install ALSPD2CORE myself?
Installation involves work at an electrical panel. A qualified electrician should confirm compatibility, grounding, breaker connection and code requirements before installation.
Will a whole-house SPD stop every possible surge?
No surge protective device can eliminate every electrical risk. Proper grounding, correct installation and layered surge protection remain important parts of protecting a home's electrical system.
