We like the Vertical Power concept, very reliable …. Installing the VP-X Pro (in the 7A here) which has two processors and two power supplies so essentially two VP-X systems in one box, belts & suspenders !
If you’re interested, spend some time on the Vertical Power website, check out the comparison charts, read their forums, check out the installation manual… very nice product.

VP Quote….. “A typical mechanical circuit breaker has a mean time between failure (MTBF) of 17,000 hours. A single electronic circuit breaker has an MTBF of about 1,000,000 hours. Further, a mechanical switch is rated for about 30,000 cycles. Our ECBs are rated for 2 billion cycles. As you can see, modern solid-state components offer significantly higher reliability”.
