This is a hybrid bench to integrate MCCB over current tripping as well as temperature rise testing as per IEC 60947 and custom based requirements. In addition, temperature rise module helps monitor the temperature rise in various parts of the system in rated current as well as over-current mode. The system comes with user interface software configured in NI LabVIEW making testing of MCCBs complete where thermal curves with current as well as temperature rise can be plotted on a PC.
The bench is purely customizable as per the R&D needs of the customer with respect to parameters. In addition, additional measurement modules can be added of different makes for precision testing, measurement and compliance.

This bench is built to test MCCB instantaneous tripping (also known as Short Circuit or Magnetic tripping) as per IEC 60947-2 Cl 8.3.3 and custom based requirements.
A speciality of the system is that it includes differently designed systems for two different current ranges (Smaller range for currents < 2000 A and higher range for currents >2000 A) thus ensuring equal reliability, accuracy and regulation for both low current and higher current MCCBs.
Specially designed custom built jigs are able to accommodate different types of MCCBs enabling the user to test all kinds of miniature circuit breakers on a single test bench. In addition, the system can be made such that it covers the entire range of MCCBs for production floors producing all ratings of MCCB.
The system can be customized for any number of fixture stations to accommodate any number of MCCB frame sizes and current ratings for thermal trip current values. Additionally, the system can be PC based, PLC based, manual, etc. The user, can, for example have, say x number of stations for a given MCCB rating / frame size and y number of stations for another MCCB rating / frame size.
This is a hybrid 3 station-bench to test MCCB thermal tripping characteristics as per IEC 60947-2 cl 6.3.3 and custom based requirements at a controlled temperature (that can be set) adding another compliance parameter to the list. The speciality of this test system is its in built heater allowing the user to conduct the test at any desired temperature.
The system is mainly used to plot / determine the MCCB thermal trip characteristics in a high / low temperature environment. The system may be supplied with a test chamber which maintains temperature, humidity. More MCCBs (of different makes) can be compared simultaneously for tripping performance.
The Test Bench will be made to serve the requirements of Thermal & Magnetic Calibration of MCCB. There will have power source with servo-controlled closed loop feedback system. The power source will have the capacity to pass 2.5 times the rated current of MCCB with 1 pole testing. For Thermal Test and 10 times of rated current for Magnetic Test of Single Pole at a time.
The fixture trolley can be separately attached to the main power source. This will help users to change the required fixture for different frame sizes. The connection between the trolley and the main source will be with bolted bus bars and clip on terminals for control circuit.
The system can be customized for any number of fixture stations to accommodate any number of MCCB frame sizes and current ratings for thermal trip current values. Additionally, the system can be PC based, PLC based, manual, etc both for Lab testing & Routine.
This MCCB testing panel is ideal for Quality control labs in switchgear manufacturing, R&D centers validating thermal & magnetic trip characteristics also for Compliance Testing as per IEC 60947-2 standards.
