This is a hybrid bench to integrate MCCB instantaneous tripping as well as overload tripping as per IEC 60947-2 cl 6.3.3 and custom based requirements. In addition, temperature rise module helps monitor the temperature rise in various parts of the system. 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 test jig is flexible such that different MCCBs can be tested and compared for their performance.
Available in multi-pole testing options
Drop down menu in the software to once select the type (rating or calibre) of MCCB: Rest of the test parameters get selected automatically (User can simply jump from one type of MCCB to other instantaneously)
IEC based test parameters automatically configured.
Software: NI LabVIEW based for user interface, settings selection, process control & report generation
Servo Controlled Voltage Regulation ensures stable voltage at the output.
Pneumatic based test jigs for correct contact at terminals.
Test results are displayed on monitor and stored against serial number or a bar code.
Generation of Reports in MS Excel format or to Print.
Exact trip current wave-form (and not a vague band) is displayed on PC.
Two or more curves can be compared on PC
Temperature Rise module can be added as an additional option.
440 V, 3 phase, 50 Hz input.
Output current programmable up to 8000 A continuous and 20000 A short time depending upon the customer requirement at a conveniently low voltage. The source capacity can be custom built to suit a typical requirement w r t the current, voltage and VA rating.
Can test MCCBs of different ratings and different number of poles on a single bench.
Test Procedure options: IEC 60947-2 / customized.
Pressure Required for pneumatic handling: Approximately 8-12 Bar depending on the MCCB size
PC provided: IBM PC / compatible make with NI LabVIEW based Testware TM.
500 VA branded UPS Temperature Rise Module: The test bench comes with an additional temperature rise module that can be integrated in to the main overload system. An advantage of this integration is that the temperature rise of a certain metallic part in the MCCB can be monitored and compared with the expected results. The module helps quality / R and D engineers to monitor any loose contacts with in the MCCB circuit that can be improved to obtain the desired quantity.
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 is a flexible bench with a lot of settable parameters.
