Use the applicable connection parts for breaker.
Otherwise it may result in fire.
(1) Front connection
1 Mounting
Mount directly using the mount hole.
Mount plate
• Mount screws for steel plate and for wood plate (a part of NV models) are attached. For dimension, refer to Appendix 1.
Note) In some cities, mounting onto wood board is limited by fire defense code and others.
Mounting on IEC rail
2 Connection
Wire connection with ring-type terminal
● For connection using ring-type terminals,
refer to Appendix 4 for selection.
Bar connection
When conductors are connected directly, process the
●
conductors to the outline dimensions stated in the
conductor machining drawing.
To connect a conductor to a bar terminal, pay atten-
●
tion to insulation to the ground. Ground fault prevent-
ing barrier can be made to your designation.
After making sure that the connecting conductors are
●
free from any contamination and deposition of foreign
matter, tighten them firmly.
● Where a connecting conductor is used, insulate the
uncovered conductors of the power supply side using
insulation barriers.
CAUTION
Taping or
insulation tube
Cover up exposed and conducting part of
●
ring-type terminals with tube or insulation
tape.
Wood screw
● Fix by attaching a slip stopper.
Fasten the ring-type terminals so that the wires
●
of different poles are kept parallel with each other.
