DUO series Contactors
SC-E series
Operation conditions
■ Standard operating conditions
The magnetic contactors are manufactured for use in the
standard operating conditions given in the table at the right.
Consult FUJI before using the magnetic contactors in different
conditions.
■ Wirings
• Connection wires and terminal processing
Be sure to perform wiring correctly with reference to the
connections diagram. Main terminals for models SC-E02 to
SC-E7 are wired using solid wires or stranded wires.
Stranded wires or flexible stranded wires can be connected
by twisting them together, crimping a sleeve (ferrule) onto
them before connecting.
• Tightening torque
If wires are not tightened sufficiently, they may become hot or
come loose and result in a fire, short-circuit, electric shock, or
some other potentially dangerous situation. Be sure to tighten
the wires to the torques specified in the tables below.

Notes: *1Stranded wire (0 to 35mm2) consists of 7 wires or less.
Stranded wire (38 to 120mm2) consists of 19 wires or less.
Flexible stranded wire consists of more number wires than the above.
*2The tightening bolt must be loosened in order to insert the wire. However, stop
loosening the bolt when the anti-drop attachment on the bottom of the bolt
reaches the top edge of the terminal. If a torque exceeding that given in the
table is applied in this state, the retaining plate may come loose.
