This is a turnkey project to design, build and supply a automated test & calibration machine for the MCCB electronic release.

The system consists of two separate test benches for single phase & three phase tests. The maximum current capacity of 3 phase set-up is 1600A and 20000A for single phase set-up. On 3 phase set-up it is possible to calibrate the electronic release for Phase, Neutral & Earth faults. The Earth fault trip test & Earth fault balanced test for RYB & RYN is carried out on 3 phase set-up. The single phase set up is designed for Long time test, Short time test, Thermal memory test & instantaneous test. On line current adjustment is possible for long term test which is done through primary voltage adjustment by a motorized variac.

The scope of work included:

1. Design and Supply of complete machine
2. Development
3. Commissioning
