Asea Brown Boveri TYPE-606 ABB-TYPE-606 Secondary Injection Test Set for Micro Power Shield (MPS) Trips
This test set is used to test ABB MPS-3, MPS-4, MPS-5, as well as MPS-3G,
MPS-4G, and MPS-5G trip units.
The type 606 Test Set is a secondary current injection tester specifically
designed to test only Micro Power Shield (Type MPS) solid state systems.
All the conecting cables required for testing are permanently attached to and
are stored within the portable case.
The type 606 Test Set can be used to determine threshold currents on the
instantaneous element as well as the threshold currents and time delays on the
long-time, short-time, and ground functions. In addition to these tests, the
MPS internal toriod board can be checked. The Test Set can also confirm that
the magnetic latch and the remainder of the circuit breaker's trip mechanism
is functioning by tripping the breaker through the MPS unit.
