    Product Detail

    Equipment Overview

    The MCB Long Delay Action Characteristics Test Bench is a professional testing device developed for evaluating the thermal long delay tripping characteristics of miniature circuit breakers (MCB).
    It is mainly used to verify whether an MCB can trip accurately within the specified time range when subjected to overload currents below the instantaneous tripping threshold.

    This test bench simulates long-duration overload conditions and precisely controls test current, timing, and temperature influence, ensuring stable and repeatable test results.
    It is suitable for routine type tests, production line sampling tests, and laboratory verification of MCB products.

    Main Functions

    • Long delay (thermal) tripping characteristic test for MCB
    • Overload current simulation under specified multiples of In
    • Accurate measurement of tripping time
    • Adjustable test current and timing parameters
    • Real-time monitoring of test status and results
    • Automatic data recording and result storage
    • Safety protection during long-duration testing

    System Configuration
