1-phase series

	MCCB
Power	R/L1
supply	S/L2

1-phase series do not have T/L3 terminal.

*1: Only European model has a built-in noise filter.

*2: The terminal can be switched between FM/OUT and VI/S3 by changing a parameter.

*3: The terminal can also be used as an input terminal by changing a parameter.

*4: European models are not provided with PO terminal.

*5: 1-phase 100V models cannot be used with DC reactors.
