The High voltage tester for routine testing of MCBs combines a conventional high voltage tester with a specially designed robust fixture to hold 20 single pole MCBs at a time. The solution comes as a single trolley with easy-to-set test parameters with safety interlocks designed for user safety with respect to electric shock and mechanical fixturing. An advantage of the system is – it gives a high yield (20 MCBs are tested in about one minute) thus yielding user safety at a high value for money.

Other than those mentioned above, the kilovolt and mA level can be custom-made. In case of routine testing solution employing mechanical test jigs, the number of MCBs (to be tested simultaneously) can be customized as 1, 4 and 20.
The product is used to test 1-4 pole MCBs as per Cl 9.7.5, IEC 60898. The test bench tests the di-electric withstand capability of the product with settable high voltage and allowable leakage current.
