    Product Detail

    Equipment Overview

    The MCCB Magnetic Trip Test Bench is a specialized testing system used to evaluate the instantaneous (magnetic) protection performance of Molded Case Circuit Breakers (MCCB). This test bench simulates high-magnitude short-circuit currents to verify whether the MCCB trips quickly, accurately, and reliably when magnetic protection is triggered.

    The system precisely controls test current amplitude, rise time, and triggering conditions, ensuring accurate and repeatable test results. It is suitable for testing MCCBs with different frame sizes, rated currents, and magnetic trip settings, and fully complies with IEC 60947-2 requirements.

    System Configuration

    The test bench typically consists of the following systems:

    • Control System
      Equipped with an advanced control system and intuitive operation panel, allowing flexible setting of fault modes, test current, and delay time parameters.
    • Power Supply System
      Provides stable and adjustable voltage and current output to meet the testing requirements of different types and ratings of circuit breakers.
    • Fault Simulation System
      Simulates various fault conditions, including overload, short circuit, and grounding, with precise control of fault current and delay time.
    • Data Recording System
      Automatically records key parameters such as operating time, fault current, and delay cut-off time, generating clear and traceable test data for analysis and evaluation.
    • Safety Protection System
      Integrated with multiple safety protections, including overload, over-temperature, and short-circuit protection, ensuring safe operation during testing.
