Overview
Not a power strip and not an outdoor box, the Siemens BoltShield plugs into a Siemens panel to protect the whole home from surges. An audible alarm and a visual indicator tell the homeowner when it has worn out.
High surge capacity and an alarm that is hard to miss make it a strong panel-level guard. Fitment is limited to Siemens panels.
Who it's for
Siemens panel owners who want surge protection at the source get a high-rated plug-in unit. Homes with other panel brands need a device made for their panel.
Pros and cons
- High surge current rating
- Audible and visual alerts
- Plugs into the panel
- Strong short circuit rating
- Siemens panels only
- Box contents not listed
- Panel space needed not stated
Performance notes
A higher surge current rating means the device can absorb larger spikes, such as nearby lightning, before failing. The nominal rating describes repeated smaller surges it handles over time. The alarm sounds once protection is spent, which matters because a worn device gives no protection.
