Portable Circuit Breaker for Protective Relay Testing

Product DescriptionProduct Model: WDS-2Prodocut Name: electrical tripping simulate device with real action coil and adjustable resistanceThe 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.Breaker closing or tripping status output Trip & close signal input (DC 40-250V adaptable)Closing or tripping LED indicationAuxiliary power supply(110V & 220V available)Action phase selection switch (3-phase , ABC, ABC single, orcustomized,  switch by pressing the button)Action coil resistance selection button (100Ω,200Ω,400Ω optional, switch by pressing the button)Manual closing buttonManual tripping buttonClosing time delay set(time=setup no.×20ms)Tripping time delay set(time=setup no ×10ms)Main FeaturesDual simulator in one small caseSmall size and weight for fast responseReal Coil resistance optional for circuit breaker simulationDIY action Phases, Action delay time and coil resistanceAuxiliary Output for product device power urgent suuplyDimension:380(W)×250(H)×180(D)mmWeight:5KgDetailed Photos   Product ParameterssimulateTripping/closing:DC signal inputVoltage: DC 40V ≤ Vin ≤ 250Vaction Coil resistance options100 Ω, 200 Ω, 400 ΩClosing delay time options20ms~180ms, step 20ms Tripping delay time options30ms~90ms, step 10ms Binary output contact capacityDC110V/5A, AC220V/30AAction phase presets:3-phase ,single phase or customizedAuxiliary DC power supply110V/220V optional, 200WDimension380(W)×250(H)×180(D)mmWeight5Kg  Company ProfileHAOMAI ELECTRIC POWER AUTOMATION is established in 1999 and located in Wuhan of China, which is specialized in developing and manufacturing electrical power test and measurement instruments.
