1、Device Overview

      The NXMK handheld simulated circuit breaker is primarily used for full-system testing of relay protection devices, as well as for replacing actual circuit breakers in other test applications; it serves as a substitute for the actual circuit breaker when conducting full-system switching system transmission tests for relay protection and automatic protection devices. It offers accurate and reliable operation with no limit on the number of operations, thereby significantly improving test accuracy and completeness, minimizing the number of operations required of the actual circuit breaker, and extending its service life. This simulation device can be used in conjunction with a relay protection verification device or independently. The equipment is powered by a lithium battery and can operate in dual-unit parallel configuration.
