DC Switch Circuit Breaker Ampere-Second Characteristic Tester

500A DC circuit breaker ampere-second characteristic tester is specially designed for substation testing, overhaul, and maintenance applications. It is used to perform overload and short-circuit characteristic tests on DC circuit breakers, thereby improving the health level of substation DC systems. By ensuring proper breaker performance, it helps prevent nuisance tripping and large-scale blackouts caused by DC distribution network failures.

Features：

The instrument can be used alone or online with a PC

Using power electronic control technology to produce large current output, the output current has a fast response speed, high precision, and continuously adjustable

Multiple high-precision sensors automatically switch the current range and high-performance 14-bit AD acquisition chip

With power-down storage function, 200 sets of test data can be stored

Automatically save the setting data, and display the last setting data after power-off

Optional ampere-second action test mode and flow-through non-action test mode

In the online mode, you can operate and control the instrument, import test data, store test data, generate data reports, generate data curves, generate EXCEL reports, etc.

The instrument has overheating, overcurrent, and overvoltage protection functions
