MCCB Standard Delay Trip Test Bench

Equipment Overview

The MCCB Standard Delay Trip Test Bench is a specialized testing device used to evaluate the long-time (delay) protection characteristics of Molded Case Circuit Breakers (MCCB). This test bench helps manufacturers ensure that their products provide reliable protection against prolonged overload conditions, by simulating these conditions and verifying tripping times based on standard settings.

The system precisely controls the test parameters, including overload current, test duration, and time delay, ensuring accurate and repeatable results that comply with international standards such as IEC 60947-2. The test bench supports flexible configuration options, allowing for different MCCB models with varying current ratings and trip characteristics.

Main Functions

• Long delay (thermal) tripping characteristic test for MCCB

• 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
