Pinpoint Defects in Micrologic, NT, STR Trip units with Square D S33595

Posted by Protec Tech Team on

Square D by Schneider S33595 Secondary Injection Test SetSecondary injection tests can pinpoint defects in a trip unit or other protective schemes ensuring that the system is functioning normally. 

A full function test kit, the Square D by Schneider S33595 Secondary Injection Test Set is designed to perform tests on Micrologic, NT and STR Trip units.

The Square D by Schneider S33595 consists of a signal-injection box which can be used alone or with a supporting personal computer (PC). The optional test kit software is compatible with Windows® 95, 98 and Windows NT® operating systems.

Without a supporting PC, the Square D S33595 may be used to check:

  • The mechanical operation of the circuit breaker
  • The electrical continuity of the connection between the tripping coil and the trip unit
  • Trip unit operation:

— Display of settings

— Operating tests on the electronic component

— Automatic and manual tests on protection functions (trip curve verification)

— Tests on the Zone-Selective Interlocking (ZSI) function

— Inhibition of the ground-fault protection for equipment

— Inhibition of the thermal imaging
