Siemens FS140 Review for 2022 – You Might Regret Not Getting it Earlier

A previous client of mine contacted me recently and hence the writing of this Siemens FS140 review. He told me a lightning strike came by a few nights ago and his surge protection strip and all connected electronics were mostly fried.

I told him having a Type 3 SPD at home is not enough to block such powerful voltage spikes and recommended that he gets a Type 2 SPD for the whole house. Type 2 SPD is a type of hardwired SPD to be setup at the main breaker panel.

Type 3 Surge Protection Devices Are Not Enough

A few days later, he called and asked if he should get Siemens FS140. In view of that, I decided to do a review of this whole house surge protector from Siemens. This is mainly for the benefit of future visitors who may be looking for a product review for the same brand and model.

In my line of work, I often hear similar horror stories from clients and friends. These people are frequent victims of huge power surges that caused expensive damage to costly electrical appliances in their home. I hope this review will help someone make a smarter buying decision and better protection their home against destructive current surges.

Who Should Buy it?

If you need a robust, reliable, and performance-ready whole house surge protection device, this FirstSurge device from Siemens will definitely fit the bill.

There is no doubt that it has a big size and price point is a little on the high side. But the surge protection features and benefits you are getting are definitely worth more than the replacement cost of your fried electronic devices and appliances.

Who Shouldn’t Buy It?

This big-size surge protection device [10 x 6 x 4 inches ] from Siemens may not fit in your breaker panel. Be sure to take measurements of your panel before getting it. So yes, obviously this is not for you if you have a panel that is unable to fit the size dimensions of Siemens FS140.

There is another reason why it may not be for you. Extra cost will be needed to buy both the Coaxial System Protection and Phone System Protection devices separately. If you do not have the budget for these extra devices, you may want to give FS140 a miss as you will not be having holistic protection against surges for the entire house.

Is the Price Reasonable?

In our opinion, the price of Siemens FS140 is a little on the high side for most homeowners. But if you consider the features and benefits you are getting from this Siemens surge device like its 140,000 amp surge rating as well as 3 stage notification diagnostic, it is still quite a worthy buy.

Our Review and Rating of Siemens FS140

Existing Buyers Review

A few buyers mentioned the surge protection device is too big for their breaker box. But did also mentioned that size does not matter if the installation is done outside the box via a conduit. Beyond that, there is not any substantial with the device in terms of quality and surge protection capability.

Minor Flaws – What to Expect

Like I stated earlier, besides the size of this Type 2 SPD being a little too big for fitting into the main service panel, there really is not an issue with the product quality.

What Else to Know About Siemens FS140?

Some buyers asked what happens next after the audible alarm goes off? Is there any way to silence it? Once the audible alarm gets activated, the device has done its job and will need replacement. Hence turning it and unplugging it from the breaker panel would silent it.

If you want a true 100% whole-house protection against surges, be ready to get an additional connector and device for both Siemens FSCATV coaxial system and Siemens FSPHONE phone system protection.

Bottom Line – Should You Get It?

You should get this whole house surge suppressor from Siemens if the size and cost are not an issue for you. Overall, I personally feel that the price is well worth the surge protection features and performance that it comes with.
