Description
Engineered for residential applications, this Siemens device integrates two 20A circuits and whole-house surge suppression into one plug-on module. It provides branch overcurrent protection while defending against voltage spikes without taking up extra panel space. The unit mounts into Siemens EQ, PL, and ES series load centers, replacing older QSA2020TVSS models. Rated 10 kAIC at 120/240V, it features a 40kA surge capacity, LED indicators, and a trip-to-notify function for system safety.Specifications

Product FAQs
8 answersHow much space does the QSA2020SPD require in a panelboard?
This device occupies two standard 1-inch circuit breaker spaces. It integrates two 20A single-pole circuits alongside the surge protective device (SPD), preventing a net loss of usable spaces in the load center.
Where is the optimal installation location for the QSA2020SPD within a load center?
For maximum surge suppression effectiveness, install the breaker as close to the main power feed or main breaker as possible within the service entrance panel.
What are the surge protection energy and impulse ratings for this device?
The SPD module delivers a 40kA maximum peak current impulse rating. The transient energy rating is 360 Joules line-to-neutral and 720 Joules line-to-line.
How do you verify the operational status of the QSA2020SPD surge protector?
The face of the unit includes two green LED indicator lights. When both LEDs are illuminated, the internal surge protection components are active and protecting the panel.
Which Siemens load centers accept the QSA2020SPD combination breaker?
This plug-on surge protector is compatible with Siemens residential load centers that accept Type QP breakers. Supported product lines include the EQ, EQL, SEQ, EQG, PL, and ES series panels.
Does the QSA2020SPD only protect the two 20A branch circuits wired to its load terminals?
No. When installed in the load center, the internal SPD component provides surge protection across the entire busbar, shielding all branch circuits in the panel in addition to the two circuits directly connected to it.
What internal components handle the transient voltage suppression in this unit?
The device utilizes heavy-duty, Siemens-built 150V AC, 40mm metal oxide varistors (MOVs) to absorb and dissipate voltage spikes.
Can the Siemens QSA2020SPD be used to replace an older ITE QSA2020SPD?
Yes. Siemens acquired ITE, and this current production model is the direct replacement for legacy ITE QSA2020SPD surge protector breakers.
