CSU600A /600AT Current Supply Units
These high-current supply units have two main elds of application. The rst is to conduct primary tests on
protective relays. A primary test shows whether all parts of the protection system are functioning together properly
within the speci ed time limits under operating conditions.
The second eld of application involves conducting current tests on low-voltage circuit breakers and overcurrent
devices.
The CSU600A is a compact instrument which, together with Timer TM200 and an external ammeter, meets
stringent requirements for accuracy, easy handling and performance. This current supply unit is ideal for a)
performance and turn-ratio tests of current transformers, b) primary tests of protective relays, c) current tests on
low- and high-voltage circuit breakers and d) commissioning tests that require variable currents.
The more sophisticated CSU600AT provides a more comprehensive solution. It has a built-in timer and an analog
ammeter that provide rough current settings quickly and easily. As a result, connection time has been reduced to the
bare minimum.
The CSU600A and CSU600AT current supply units have an excellent weight/performance ratio. CS

Application example
IMPORTANT!
Read the Users manual before using the instrument.
Primary test of protective relay equipment and low-voltage
circuit breaker
1. Connect the CSU600A's current outputs across the current

transformer (diagram a) or to the breaker terminals (diagram b).
2. Connect Timer TM200's start input to output T and the stop input

to the protective relay equipment's auxiliary contact.
3. Set the current.
4. Execute the test.
5. Read the time from Timer TM200.
