Test Equipment

Hand-Held Test Kit

The hand held test kit may be used to:

• Verify trip unit operation, the mechanical operation of the circuit breaker, and the electrical continuity of the connection between the trip solenoid and the trip unit.

• Supply control power to the trip unit for settings via the keypad when the circuit breaker is open (MicroLogic type A, P or H trip units).

• Inhibit thermal imaging for primary injection test (MicroLogic type A, P or H trip units).

• Inhibit ground fault for primary injection test (MicroLogic type A, P or H trip units).

• Self-restrain zone-selective interlocking (ZSI).

Full-Function Test Kit

The full-function test kit can be used to verify LSIG functionality.

• Optional

• Can be used to check trip unit operation, for example:

  • 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) functions.

  • Inhibit thermal imaging for primary injection testing.

  • Self-restrain zone-selective interlocking (ZSI).

• Can also be used to:

  • Check mechanical operation of the circuit breaker.

  • Check the electrical continuity of connection between the trip solenoid and the trip unit.

  • Print the trip unit and circuit breaker test report when used in conjunction with a PC

  • FFTK report generator software (cat. no. FFTKRPT-V1-0) is required.

Service Interface

The Service Interface is a portable test instrument designed for field testing. It is used for configuring various Schneider Electric circuit breakers and communication accessories. The Service Interface replaces the Full-Function Test Kit (FFTK) and the Universal Test Adapter (UTA).

The Service Interface is powered by a 24 V SELV power adapter and the test port is compatible with all supported devices with various cable accessories. In additions, the communications LEDs on the Service Interface indicate the status of the circuit breakers and communication accessories connected to it.

EcoStruxure™ Power Commission (EPC) software is the user interface for testing the circuit breakers and communication accessories through the Service Interface.

Use the Service Interface to perform the following tests on the communicating trip units through the EcoStruxure Power Commission Software:

• Automatic Trip Curve Tests

• Device Check (Force Trip Test)

• Zone-Selective Interlocking Test (ZSI)

• Preparation for Primary Injection Tests.

Please contact the SE Service Team for Breaker Test Services and for the Service Interface. The EcoStruxure Power Commission Software is available for download from SE.com.
