TTS Adapters



Marwell’s TTS-Temporary Test Switch is designed to allow full meter site access of transformer rated meter sites that do not have test switches, including sites with automatic bypass meter sockets. The Marwell TTS (Temporary Test Switch) adapter will temporarily place a test switch into the metering circuit. The meter man will be able to completely test the site using conventional testing equipment in the same manner as his/her normal CT rated meter sites.



The TTS adapters are available in three standard models.
TTS-6: Used for meter forms 3s and 4s sites
TTS-8: Used for meter forms 5s, 35s and 45s
TTS-13: Used for meter forms 6s and 9s
Please specify, ring style or ringless application.
