Siemens' line of factory installed internal and external TPS3 SPDs (switchgear, switchboards, panelboards, MCCs, busway and more) consistently assures optimal performance through direct bus bar connections or minimal cable connections. This translates to some of the industry's best installed voltage protection ratings (VPRs) and surge current capacities ranging from 100kA to 1000kA. 

 

Features and Benefits:

  • TPS TranSafe Enabled – Our patented TranSafe fault current protection circuitry provides peace of mind that your electronic loads are protected and that your electrical system will not go down due to SPD fault control operations.
  • Integral or Internally Mounted for Optimized Protection – Internal surge protection dramatically reduces installation impedance allowing for superior installed suppressed voltage capabilities.
  • SAD/MOV Hybrid Suppression – For mission critical applications needing the absolute best suppressed voltage, our hybrid SAD/MOV suppressors combine tight clamping technology with integrated suppression, delivering the strongest installed protection capabilities available.
  • Retrofits – TPS3 01 and TPS3 09 Field retrofit within our P1 and our previous S1 distribution panel boards. When your needs change, Siemens TPS gives you the flexibility to retrofit Siemens panels with internal surge protection replicating factory installation.
  • Low Suppressed Voltage Ratings –  TPS Family offers some of the lowest UL 1449 listed suppressed voltage ratings available, meaning your electronics will last longer when compared to SPDs with higher ratings.

Suppressing surge voltages to harmless levels is the primary means hardwired SPDs protect electronics and electrical loads. This function is enhanced or inhibited depending upon the length of the SPD's connecting cables. 

 

Features and Benefits:

  • Low Suppressed Voltage Ratings –  TPS Family offers some of the lowest UL 1449 listed suppressed voltage ratings available, meaning your electronics will last longer when compared to SPDs with higher ratings.
  • TPS TranSafe Enabled – Our patented TranSafe fault current protection circuitry provides peace of mind that your electronic loads are protected and your electrical system will not go down due to SPD fault control operations.
  • Flexibility – Whether you need compact design or extra redundancy, Siemens TPS family of hard wired TVSS/SPDs will have a solution to meet your needs.

Our FirstSurge line of residential surge products offers commercial class protection for the whole house. When a replacement becomes necessary, FirstSurge is equipped with 3-stage diagnostics to properly notify homeowners. The balanced protection and robustness of our FirstSurge units provide assurance to homeowners that their modern homes and appliances are fully protected.

Siemens' FirstSurge devices are designed to stop surges before they enter in order to prevent that damage from happening and protect the whole house.

 

Features and Benefits:

  • Surge Current Capacity – FirstSurge offers three different surge protector sizes based upon geographic location and thunderstorm  activity. 
  • 3-Stage Diagnostics – When FirstSurge wears out, the protection status LEDs extinguish, an audible alarm beeps, and a red service light flashes to warn the homeowner.
  • Modes of Protection – The electrical system's primary paired conductor combinations of L-N, L-G, and N-G are directly surge protected.
  • Balanced VPR Protection – All primary paired conductors are surge protected in a balanced manner with 600V UL1449 VPRs.
  • Ground Reference Monitoring – GRM diagnostics monitor the health of a home's neutral to ground bond and alert the homeowner if the bond becomes loose, preventing a potential safety issue.
  • Safety – FirstSurge can achieve UL1449 listed 100kA SCCR, one of the highest ratings for residential surge protection.

FirstSurgeTM - Residential Surge Protection

To effectively surge protect ALL of your home’s equipment, Siemens developed the FirstSurge™ family of surge protective devices. They stop surges right at your incoming services before they can travel down the power, cable and telephone lines damaging your equipment.

Siemens FirstSurge™ stops power surges from entering your electrical system protecting smart appliances, TVs, computers, heating and cooling systems and more. Every FirstSurge™ includes commercial class notifiers (LEDs, Audible Alarm, and Red Flashing LED) and supplemental GRM Diagnostics.
