Need a 200A - 3 phase changeover switch for a project in work but can't find one on the web anywhere.
Can anyone help?
Situation is this,
Test panel comprising 3 phase - 170A test circuit,
3 phase - 15A test circuit,
440VDC - 170A test circuit,
440VDC - 15A test circuit,
Single phase - 240v - 15A test circuit.
We now have a 270A 3 phase inverter which is currently wired into the 3 phase - 170A contactor purely for testing the inverter at the moment. However, when it has passed its test/inspection the plan is to feed it from the main test panel thereby incorporating all the e/s switches and safety lockouts. From a safety point I have stipulated that the inverter must not be capable of being energised if the main panel is being used to test a motor and vice versa. So I am looking for a changeover/isolator switch to prevent this happening. The type I have in mind is a 3 position switch with the central position being off and the upper and lower positions controlling the test panel and inverter respectively.
Do you understand what I am trying to say?
If anyone could point me in the right direction or offer any advice it would be greatly appreciated.
Thanks.
