Key Specification Ratings
Maximum Continuous Operating Voltage (MCOV) – 7.5/10
Why Did It Earn this Score? – As far as MCOVs go, the Schneider Electric QO2175SB doesn’t do much to distinguish itself from the pack. That’s okay, though, because this model’s primary use in light industrial and residential environments allows its two differentiated MCOVs to meet user’s surge protection goals. So, if your whole home surge protection needs only call for 150-300 volts of MCOV, then this model’s L-N and L-L modes will serve you well.
Voltage Protective Rating (VPR) – 9/10
Why Did It Earn this Score? – Schneider Electric has a variety of modular surge protectors available right now, but few manage to match the QO2175SB model when it comes to VPR. This model’s low-end VPR, 700 volts, is higher alone than the high VPR settings on other models offered by this manufacturer. Meanwhile, this model’s top VPR, 1,500 volts, blows other compact surge protection devices out of the water while remaining entirely affordable.
Mode of Protection – 7.0/10
Why Did It Earn this Score? – While the Schneider Electric QO2175SB may excel in VPR, it still suffers from an issue seen in other surge protectors from this manufacturer – the bare minimum when it comes to modes of protection. Specifically, this model only allows users to utilize the common L-N and L-L modes, while leaving L-G and N-G by the wayside. While this isn’t a major issue for most users, seasoned surge protector users may need to look elsewhere for more operational options.
Cumulative Score Average – 7.9/10
Though its modes of protection and MCOVs leave a bit to be desired, the Schneider Electric QO2175SB is a worthwhile choice that will reliably ensure that your home is protected from external surges of up to 22,500 amps. While it performs best with a QO load center, this model’s individually fused MOVs will perform effectively regardless of your chosen indoor set up. Also, the Schneider Electric QO2175SB drives an undeniable bargain, between its approximately $50 price tag and its multi-year warranty.
