You cannot use the Square D Full-Function Test Kit (FFTK), Hand-held Test Kit (HHTK) or Universal Test Set (UTS3) to test the new Micrologic 3/5/6 trip units found on PowerPact H, J and L frame molded case breakers. You will instead need the Schneider Electric Pocket Tester (S434206) or UTA Tester (STRV00910) to secondary test these trip units.
The Pocket Tester is similar to the old Hand-Held Test Kit. It is a stand-alone battery powered device that can be used to power up the trip unit in order to change trip settings on the circuit breaker, inhibit thermal memory and perform a simple trip test.
The UTA Tester, shown below, is more like the Full-function Test Kit where it provides complete access to the trip unit parameters and settings.
The UTA test set can be used by itself to power the trip unit, allowing for trip unit settings, or in conjunction with a laptop computer with the Schneider Local Test Utility (LTU) or Remote Setting Utility (RSU) software installed. The RSU software allows set up of the trip unit while the LTU software performs all of the tests.
Don’t learn this lesson the hard way. A Project Manager sent his technicians a full-function test set to secondary test several HG and JG frame breakers during a scheduled power outage. The technicians were unable to use the equipment so the outage had to be canceled and it was very embarrassing for the company.
