The test bench can be customized as per the rated current range of the RCBOs (typically upto 63 A and upto 125 A). Additionally, The bench can be made to test MCBs also. The number of temperature measurement channels can be customized as per the client preference. Further customizing options are micro-controller based / PC based with fully automatic seection and testing plus report generation. The equipment can be clubbed with 28 days testing equipment.
The test, similar to that of an MCB, is carried out to measure the power loss across each pole, i.e. what are the losses per pole in an MCB. Also temperature rise of various parts - including current carrying parts can be measured. Thus, the reasons for power loss can be assessed.
