Products Features:
The circuit breaker adopts full digital circuit, and the time is set by digital dialing. It can
realize the functions of analog circuit breaker tripping and closing time setting, three-phase /
split phase operation selection, input signal logic control, etc., so as to simulate the
circuit breaker tripping and closing action.
1. The power supply voltage of this instrument is DC220V and DC110V, the voltage must
be consistent with the input voltage before the test;
2. This simulated circuit breaker can simulate split-phase operation circuit breakers, and
can also simulate three-phase operation circuit breakers. The choice of tripping and closing
impedance is 400 ohms, 200 ohms, and 110 ohms. When simulating split-phase operation
circuit breakers, its The tripping input terminals are A close, A trip, B close, B trip, C close,
and C trip; when the three-phase operation circuit breaker is simulated, the tripping input
terminals are three trips and three closes. In addition, there are manual closing and manual
tripping buttons on the panel, and there are tripping and closing signal lights, which are three
red signal lights of A close, B close, and C close, and three green signal lights of A trip, B trip,
and C trip. When simulating a three-phase operation circuit breaker, the three-phase signal
lights of A, B, and C simultaneously turn off and on;
3. Relays A, B, and C each output a set of switching contacts in the analog circuit, and the
contacts with dynamic break contact closed or open contact disconnected are completely
isolated from the operating power supply and can be relayed from the microcomputer
cooperating with protection test equipment;
4. The analog circuit breaker can simulate the tripping and closing time, the time setting is
set by the DIP switch, and the precision is high. The setting range of trip time is 20-200ms,
and the setting range of closing time is 20-100ms.
