3.1 Introduction
The SACE PR010/T unit is an instrument capable of performing the functions of testing,
programming and reading parameters for the protection units equipping ABB SACE low-voltage
circuit-breakers. For the specific functions, refer to the respective protection unit. All of the
functions mentioned may be carried out "on board" by connecting the SACE PR010/T unit to the
front connector on the protection unit. Two different types of test are available: automatic and
manual. It is also possible to perform the trip test through the SACE TT1 unit.
By connecting to a PC (using the disc supplied by ABB SACE, or SW downloaded from the ABB
Internet site) it is possible to upgrade the software of the SACE PR010/T unit. The unit can also
save important test results, which may then be downloaded to a PC following a request for a test
report.
The SACE PR010/T test unit is a portable instrument operated by rechargeable batteries and/or an
external power supply.
