Technical Note (Arc Space, Reverse Connection); Technical Note (Performance Of Withstand Voltage) - Mitsubishi Electric AE-SW Series Instruction Manual

Technical note
■ Arc space
When the short circuit is interrupted, hot gas blows out discharged from the exhaust port of the arc-extinguishing cham-
ber, so provide a clearance as shown in the following table.
In case of drawout type, secure appropriate space to prevent the fingers from getting trapped at the time of drawing.

■ Reverse connection available
Line and Load is not defined on the Main circuit terminals.
Therefore reverse connection is available without any limitation.
■ Performance of withstand voltage
Between the live parts of the main circuit and earth
Between the live parts of different poles
Main circuit (Note 1)
Between the main upper terminals and lower terminals
Between the live parts of the main circuit and the control circuit terminal block
Between the accessories control circuit
Control circuit
Between the ETR control circuit
Note 1: Disconnect the UVT voltage input wires (D1, D2) during withstand voltage test.
(In the case of AC380-460V spec., disconnect the voltage input wire (IN1, IN2) of UVT external unit.)
Note 2: The Accessories are AX, MD, UVT, CC, SHT and AL.
Note 3: The electronic trip relay terminals(P1, P2, 513, 524, 534, 544, 554, 564, 574)
Note 4: AE4000-SW ~ AE6300-SW of Drawout type is 4kV.
