Eaton BRNSURGE Type BR Whole-Panel SPD
The Eaton BRNSURGE is designed to protect the entire panel by mounting as a whole-panel surge protector. It uses 2 branch circuit spaces and supports a surge current rating of 18 kA, making it suitable for protecting downstream circuits and connected devices from voltage spikes. This device is a practical choice for users seeking comprehensive protection within a BR-type panel configuration.
Eaton BRPSURGE Breaker, Surge Device
The BRPSURGE is a Type 2 surge protection device with a plug-on neutral design. It provides 120/240 VAC protection for 1-phase, 2-pole systems and includes an LED indicator for status. This single device is positioned to protect the entire downstream electrical system, aligning with Eaton’s CHSP approach for robust surge protection and safety.
Siemens QSA2020SPD Whole House Surge Protection
The Siemens QSA2020SPD provides whole-house surge protection, occupying space equivalent to two single-pole breakers while including two extra breakers for load management. With 150 VAC rating and 40 mm metal oxide varistors, this SPD protects the entire panel and downstream circuits from surges, making it suitable for comprehensive residential protection.
Siemens QSPD2A035B 35 KA Surge Device
The QSPD2A035B is a 35 kA per-phase surge protector designed for Siemens load centers. It features green/red mechanical indicators to notify homeowners of protection status (non-LED visual indicators), supporting easy status checks and ensuring surge protection availability at a glance.
ABB THQLSURGE2 Type 1 Surge Protector
ABB THQLSURGE2 is a Type 1 SPD designed to shield an entire home or office from surges. It supports plug-on installation and includes LED indicators to display operational status. The unit is compatible with PowerMark load centers and aligns with NEC 2023 Article 230.67 requirements for essential surge protection in residential and commercial settings.
Buying Guide
Key considerations when selecting a circuit breaker surge protector include compatibility with your panel type, surge current rating, and installation preferences. For whole-panel protection, consider devices that occupy multiple spaces or provide plug-on-neutral options for Type 2 protection. If you want a single device to guard downstream circuits, Type 2 or Type 1 SPD models from Siemens, ABB, or Eaton offer robust protection with status indicators.
Surge current rating and clamping voltage determine how much protection is provided during a surge. Higher ratings typically offer better protection for sensitive electronics, but they must match panel space and conductor capacity. Visual indicators (LED or mechanical) help verify protection status at a glance. Installation flexibility—whether a unit plugs directly into a service panel or requires mounting within a load center—affects ease of retrofitting existing homes.
Panel compatibility is critical. Siemens devices often target Siemens load centers, while ABB and Eaton offer broad compatibility with common residential panels. For comprehensive home protection, a combination approach—a main panel surge protector plus downstream protection—can be effective. Always consult a licensed electrician to ensure proper sizing, bonding, and NEC compliance for your specific installation.
