Questions about this product
- Will this surge protector work with my single-phase home electrical panel?
- Yes, it works perfectly for standard homes. You can choose the 1P or 2P configuration for single-phase systems, while the 3P and 4P options handle three-phase setups. It safely manages systems operating up to 385V AC.
- How do I mount this surge protector, and what wire size should I use?
- This device snaps directly onto any standard 35 mm DIN rail. For wiring, the heavy-duty screw terminals accept wire sizes from 1.5 mm² up to 35 mm². We recommend installing a 63A backup fuse to complete the installation safely.
- How fast does this device react to a power surge, and how much current can it handle?
- It reacts in less than 25 nanoseconds to divert dangerous voltage spikes away from your equipment. Depending on the specific model variant, it handles maximum discharge currents from 40 kA up to 120 kA. The voltage protection level stays safely at or below 1.5 kV.
