Benefits
By installing a Siemens Circuit Breaker and Surge Protective Device (SPD) in the
load center of the residence, surge protection is provided for all branch circuits
a
.
Two green LED indicator lights are provided to show that surge protection is pro-
vided for all circuits connected to the load center. These breakers should be used
for circuit protection of frequently used household or facility circuits because the
lights and devices connected to these circuits provide an effective indication that
surge protection is being provided.
The circuit breaker and SPD utilize Siemens-built 150V AC, 40mm, metal oxide
varistors (MOVs). The maximum impulse rating for the SPD module is 40kA. The
standard interrupting rating for the circuit breakers is 10k AIC. All Type QP circuit
breakers and SPD are plug-on style, with load terminals provided. The devices
are rated for 120/240V AC and are calibrated for 40 degrees C maximum ambient
applications.
