Transient Voltage Surge Suppressor

Summary: This article explains what surge devices are available and how they can help protect your motor-driven appliances by installing transient voltage surge suppression devices.

Surge Protection for Home Motor-Driven Appliances

Surge Protection Devices for Motor-Driven Appliances

This Transient Voltage Surge Suppressor provides protection against electrical power surge damage, including lightning, from entering through the main electrical service panel.

Transient Voltage Surge Suppressor

Transient Voltage Surge Suppressor TPSA9040 shields motor-driven appliances in residential and light commercial applications against electrical power surge damage, including lightning, from entering through the main electrical service panel.
Multiple MOV technology with thermal disconnects to prevent catastrophic failure. The two LED lights indicate protection status. An audible alarm alerts you when protection is disrupted. The Siemens warranty covers lightning damage during the warranty period. Major household appliances are covered against surge damage for 3 years when a TPSA9040 is installed by a qualified electrician. If the TPSA9040 surge protector is damaged, for any reason, during the first 5 years of ownership, Siemens will replace it free of charge!

Circuit Breaker and Transient Voltage Surge Suppressor

The Siemens circuit breaker and transient voltage surge suppressor is comprised of a highly effective TVSS module integrated with (2) 1-pole circuit breakers. This device incorporates the robust features of our secondary circuit breaker surge arrester with a lower clamping voltage ratings.

Two red LED indicator lights are provided to show that surge protection is provided for all circuits connected to the panel board. 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 transient voltage surge suppressors utilize Siemens-built 150V AC, 40mm, metal oxide varistors (MOV's). The maximum impulse rating for the TVSS module is 40kA. The standard interrupting rating for the circuit breakers is 10k AIC. The circuit breakers are SWD and HACR rated.

All Type QP circuit breakers and transient voltage surge suppressors 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.
