Siemens QSA2020SPD

Siemens SPD Circuit Breaker and Surge Protective Device, Residential, 240 V, 1 Phase, 20 A, 10 kA Interrupt, Thermal Magnetic Trip, 2 Pole, Plug-In, Panel Mount, 40 deg C, 4.5 Inch L x 3.3 Inch W x 2.2 Inch H

The Siemens circuit breaker and surge protective device (SPD) is comprised of a highly effective TVSS integrated with (2) 1-pole circuit breakers. This device incorporates the robust features of a secondary circuit breaker surge arrester with a lower clamping voltage ratings. Two green LED indicator lights are provided to show that surge protection is provided for all circuits connected to the panelboard. As a Siemens exclusive feature, the device notifies the owner of loss of surge protection by tripping one or both of the circuit breakers. 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. If one or both of the circuit breakers have tripped, turn both circuit breakers to the "OFF" then "ON" position. If either light is not illuminated, the device may still be used for circuit protection, but surge protection is no longer provided and the device should be replaced by a qualified electrician. The circuit breaker and SPD utilize Siemens-built 150 VAC, 40mm, metal oxide varistors (MOVs). The maximum impulse rating for the SPD module is 40 kA. The standard interrupting rating for the circuit breakers is 10 kAIC. The circuit breakers are SWD and HACR rated. All type QP circuit breakers and SPD are plug-on style, with load terminals provided. The devices are rated for 120/240 VAC and are calibrated for 40 deg C maximum ambient applications.
