Questions about this product
- Will this surge protector work with my home's single-phase electrical panel?
- Yes, it works great for single-phase systems. You should select either the 1P or 2P configuration for standard 220V AC residential setups. For three-phase commercial systems, we offer the 3P and 4P variants that handle up to 385V AC.
- Should I choose the 40kA or the 60kA version for my building?
- Choose the 60kA version if your area gets frequent lightning strikes or has unstable grid power. This higher rating channels larger surge currents safely to the ground. For standard residential protection against typical everyday spikes, the 40kA model is usually sufficient.
- How do I install this surge protective device in my breaker box?
- This device snaps directly onto a standard 35mm DIN rail inside your electrical panel. You connect it using the integrated screw terminals. We highly recommend using a 63A backup fuse and hiring a licensed electrician to handle the wiring.
