MCB Thermal Trip Calibration Test Bench

This product is used by leading MCB manufacturers on their production floor to test and calibrate the thermal tripping time (upto 60 seconds) for 2.55*I_n.

The product can be customized as per the number of stations: 1 (stand alone), 2, 4, 6, 8, 10 and 12 stations. Additionally, the product can be microccontroller based with each microcontroller controlling an individual station, or a PC based wherein the PC controls all the stations simultaneosuly and independenly of each other. The product is available as a standalone module with micro controller based control – without the use of PC as a low cost alternative with features as scalability and accuracy intact.

Description

The test system is designed and customized to carry out 2.55*Intest as per Table 7 (test c) of IEC 60898 (also mentioned for routine testing of MCBs. The test is done at dc current to exactly analyze and correct the bimetallic properties of the MCB as far as thermal tripping is concerned. The unit comes with a pneumatically operated test fixture with in-built dc stepper motor that is controlled by a micro controller / PC to calibrate the breaker into a narrow tripping band programmed by the user.
