Surge Protective Device · 120/240V · Type 1 Plug-On Whole-Home Protection · ABB THQLSURGE2
Type 1 plug-on surge protective device for 120/240V residential or light commercial panels, designed for service entrance or subpanel protection in compatible ABB PowerMark load centres. Rated 25 kA per phase with LED status indication; typically selected to protect the full panel and connected loads from utility and lightning-related surges.
What this product is for
The THQLSURGE2 is a residential surge protective device (SPD) that mounts inside a compatible load centre to help protect the entire panel and downstream branch circuits from transient overvoltage events. It is intended for 120/240V, 1-phase, 3-wire systems in service entrance or subpanel applications.
Use for
- Whole-home surge protection in compatible ABB PowerMark load centres
- Service entrance or subpanel installations
- Protection of appliances, electronics, office equipment and other connected loads
- Residential renovations and new construction where panel-level surge protection is required or specified
Avoid for
- Panels that are not listed as compatible by the manufacturer
- Applications requiring a different SPD type, voltage system or mounting method
- Outdoor exposure or locations outside the panel enclosure unless specifically engineered for that installation
Best for
Electricians and contractors adding compact panel-mounted surge protection without using extra wall space or external conduit. This model is best suited where a plug-on SPD is preferred for a clean load-centre installation and visible LED status indication.
Installed in
Compatible ABB PowerMark load centres, typically at the main service equipment or a subpanel. Unit dimensions are approximately 3 in H x 3.37 in W x 3 in D (76 x 86 x 76 mm), which helps when planning panel space and cover clearance.
Why this product exists
Panel-level surge protection is used to intercept incoming surge energy before it reaches branch circuits and connected equipment. A whole-home SPD is commonly used as the first layer of protection for sensitive electronics and appliances. Actual protection performance depends on installation conditions, grounding, bonding, system layout, and local electrical code.
Compared with similar products
Compared with point-of-use surge bars, this Type 1 SPD protects at the panel level and is typically installed closer to the source of incoming surges. Compared with larger external SPDs, the THQLSURGE2 offers a compact plug-on format for compatible load centres. It is rated 25 kA per phase with 10 kA nominal discharge current and includes LED indication for status monitoring.
