MCCB Standard Delay Trip Test Bench for China Suppliers and Factory - Accurate IEC 60947-2 Compliance Testing
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
- Safety protection during long-duration testing
System Configuration
The test bench typically consists of the following systems:
Equipped with an advanced control system and intuitive operation panel, allowing flexible setting of fault modes, test current, and delay time parameters.
Provides stable and adjustable voltage and current output to meet the testing requirements of different types and ratings of circuit breakers.
Simulates various fault conditions, including overload, short circuit, and grounding, with precise control of fault current and delay time.
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.
Integrated with multiple safety protections, including overload, over-temperature, and short-circuit protection, ensuring safe operation during testing.
