    Product Detail

    Equipment Overview

    The MCB Delay Action Characteristic Test Bench is a specialized testing device designed to evaluate the delay action (thermal tripping) characteristics of miniature circuit breakers (MCBs). It accurately simulates fault conditions such as overload and short circuit to verify the delayed cut-off performance of circuit breakers during fault events.

    The test bench complies with both national and international standards, including IEC60898-1 / EN 60898-1 / UL 489, making it suitable for quality inspection, performance evaluation, and type testing in production and laboratory environments.

    Main Functions
    • Accurate testing of delay action (thermal tripping) characteristics of small circuit breakers
    • Simulation of overload, short-circuit, and leakage fault conditions
    • Evaluation of delayed cut-off time and operating behavior during fault events
    • Suitable for MCB current action characteristic testing
    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.
