MCB laboratory of NRI, started to work since 2001 with the purpose of quality control
of miniature circuit breakers. Now, all tests of MCB are applicable in this laboratory
according to IEC60898-1. Because the manufacturers and importers also need to check
the quality of the other type of circuit-breakers, MCB laboratory worked on expanding
of its scope of work on other products such as fuse-combination switches, switches,
low-voltage circuit-breakers, RCBO's, RCCB's, contactors, …. Now in MCB laboratory
much type of tests is performed on low voltage switchgears and control gears.
Development activities:
• Last year this laboratory equipped with some new test equipments as below:
• Impulse voltage generator with peak voltage of 2-24kV and 1.2/50µs waveform.
• Tripping characteristic test system in three units for performing thermal and
magnetic tests of MCB's.
Obtained Certificates:
• IRAN accreditation system certificates No: T/703.
• Quality management system certificate according to ISO/IEC 17025 numbered
