MCB-Thermal-Calibration-Verification-Test-Bench

MCB Thermal Verification Test Bench (IEC 60898 Table 7 (Test C))

Routine Test

The test system is a special version of the thermal test test system in the sense that the test jig is primarily designed to hold and connect multi pole MCBs for thermal verification so that each pole can be verified to trip within the IEC time band after the MCB has been riveted. This test ensures the trip verification of MCB so as to trip all the 4 poles at once when overload is detected in one single pole. In short, this is a verification-only bench.
