## Overview

The Siemens QSPD2A035B is a high-performance indoor surge protective device delivering 35kA surge current protection per phase. Designed for plug-in installation into Siemens load centers, it features mechanical green/red indicators for easy status monitoring without LEDs. Compact and reliable, it safeguards your entire facility’s electrical system from damaging surges, ensuring uninterrupted operation and peace of mind.

## Description

Surge Protective Devices (SPDs) provide the best protection from both externally and internally generated surges when located as close to the building distribution system as possible. For cost and space reasons many buildings only include one SPD located at the main incoming load center and do not cascade SPDs throughout the building as recommended by IEEE. Siemens QSPD series of SPDs are economical and easy to install in most panels throughout a building so that whole facility protection can be obtained.

Review: Easy to install - It’s difficult to know if it works because nothing should happen. Nothing has happened. So that good.
Review: This Item works as Intended. And it is not supposed to light up. - This Item Does Not Have Any lights or LEDs in it, so don't worry if it doesn't light up. It does Not Need any lights or LEDs in it. It is not a circuit breaker, and will not "trip" like a circuit breaker, and then can be reset. The indicator window is only that, a viewing window. If the windows are Green, then the device is working properly. If one or both of the windows are red, that means the device has faulted, and manually flipped the indicator color in the viewing windows. Plain and simple, if this device lights up then you have a major problem. Just trust me, I'm an Electrician and install these all the time. Also, there is No Way to test these unless you want to send a surge through your power meter over what the device is rated for. Go ahead and do that while you blow up everything in your house at the same time. Again it's a surge protective device SPD that operates according to voltage fluctuations, and Not a circuit breaker which operates due to the amount of amps being used. They are completely different things.

## Features

- Fits into existing Siemens load centers
- 35kA surge current protection per phase
