    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.
