Portable Circuit Breaker for Protective Relay Testing

Product Model: WDS-2
Prodocut Name: electrical tripping simulate device with real action coil and adjustable resistance
The WDS-2 dual circuit breaker simulator can independently simulate all functions of two sets of circuit breakers simultaneously, mainly used to replace real circuit breakers in relay protection or other automatic device tests.
Each simulator can simulate the three-phase or split phase tripping and closing of a single trip coil or double trip coil circuit breaker; It can be used to simulate the on/off test of switch backup automatic switching devices, and simulate the behavior of switches such as tripping and closing rejection.
The tripping method can be either manual or automatic, and the resistance and time of the tripping and closing coils can be set according to the test needs.

1. Breaker closing or tripping status output
2. Trip & close signal input (DC 40-250V adaptable)
3. Closing or tripping LED indication
4. Auxiliary power supply(110V & 220V available)
5. Action phase selection switch (3-phase , ABC, ABC single, orcustomized,  switch by pressing the button)
6. Action coil resistance selection button (100Ω,200Ω,400Ω optional, switch by pressing the button)
7. Manual closing button
8. Manual tripping button
9. Closing time delay set(time=setup no.×20ms)
10. Tripping time delay set(time=setup no ×10ms)

1. Dual simulator in one small case
2. Small size and weight for fast response
3. Real Coil resistance optional for circuit breaker simulation
4. DIY action Phases, Action delay time and coil resistance
5. Auxiliary Output for product device power urgent suuply
6. Dimension:380(W)×250(H)×180(D)mm
7. Weight:5Kg
