Circuit Breaker Short-Circuit Test Bench

 Circuit Breaker Short-Circuit Test Bench is a specialized high-precision testing equipment used to simulate short-circuit faults in power systems and evaluate the interrupting capacity and reliability of circuit breakers. By outputting controlled high-magnitude short-circuit currents (ranging from several kA to over 200 kA), it verifies whether the circuit breaker can quickly interrupt the fault within the specified time and whether its insulation and mechanical performance remain intact after interruption. It is a core piece of equipment for circuit breaker research and development, type tests, factory sampling inspections, and third-party certification.

• The test bench is composed of integratedtouch screen, AC instantaneous currentsource, DC instantaneous current source,current lifter, high-precision transformer,button, indicator light, and other newcomponents
• It can comprehensively measure andidentify the instantaneous (short circuit)action characteristics of miniaturecircuit breakers;
• The USB interface of the device can beconnected to the scanner to quickly input theinformation of the tested object, and can alsobe used for data export
