AMETEK CTS
Example of external circuit breaker
Circuit breakers in the building are designed for 32 A. A circuit breaker box with 16 A protection is installed
between the building supply and the test generator.
Test generator and EUT are now fused for 16 A rated current
6.5.
EUT power ON/OFF with supply Line to Line (400V)
To operate the generator internal CDN with line to line voltages of 400 V,
the generator must be designed for this higher line to line voltage
CAUTION
The internal electrical switch interrupts the power on line L. Using a two-phase supply (L-L), the second line is connected to
the Neutral EUT path and can't be interrupted by the generator. The following setup with an external contactor will interrupt
both lines L1 and L2 (connected to N-path). It is controlled via the potential-free contact of the warning lamp.
The design and installation of the contactor is in the responsibility of the user.
