Can an impulse-type power supply be used for electrical opening and closing order of Compact NS MCCB ?
Yes, the impulse-type power supply (time duration > 20 ms and Voltage level above 0.7Un) can be used for electrical opening and closing of Compact NS MCCB.
The power supply during the closing order is also impulse-type as the closing order is in series with the "Ready to close" switch. Hence even if the power supply is cut-off the breaker will close.
