Product No: LS-RCT-500MA
The LS-RCT-500MA residual current device (RCD) operating characteristic tester is used to test the operating characteristics of various residual current protection devices and circuit breakers, verifying whether their response performance under specified residual current conditions meets safety requirements. This equipment outputs stable current and voltage signals, and through precise control of test parameters, simulates residual current scenarios under different operating conditions to test the operating characteristics of protection devices of different specifications and types. During the test, it accurately records key data such as operating time, supports multiple phase and polarity selections, meets the testing needs of different types of protection devices, provides a reliable basis for product quality verification and safety performance evaluation, and ensures that electrical systems can promptly cut off power in the event of a fault, avoiding the risk of electric shock.
