    Product Detail

    Equipment Overview

    The Motor Protector Circuit Breaker Delay Characteristic Test Bench is a specialized testing system used to evaluate the delay tripping characteristics of Motor Protection Circuit Breakers (MPCB).
    Motor protectors are widely used to safeguard motors against overload, phase loss, and prolonged abnormal operating conditions, making accurate delay testing essential for reliable motor protection.

    This test bench simulates continuous overload currents and precisely measures the tripping time of MPCBs under defined current multiples. It supports testing across different rated currents, frame sizes, and protection settings, ensuring accurate validation of motor protector performance.

    The system integrates stable current injection, precise timing measurement, and automated data acquisition, ensuring high repeatability and compliance with IEC 60947-2 and IEC 60947-4-1 requirements. It is suitable for production testing, quality control, and certification laboratories.

    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.
