5-4 Branch-circuit protection
5-4-1 Circuit protector
This breaker is used to switch the control power and to provide overload and short-circuit protection.
When connecting a circuit protector or breaker to the power input (TE3 terminals L11 and L21) for the
control circuit, use a product that does not trip (incorrectly activate) by a rush current when the power is
turned ON. A circuit protector with inertial delay and an operation delayed type breaker are available to
prevent unnecessary tripping. Select the product to be used according to the machine specifications.
The rush current and rush conductivity time differ according to the power impedance and power ON
timing, so select a product that does not trip even under the conditions listed in the following table.
POINT
When collectively protecting the control circuit power for multiple units, select a
circuit protector or breaker that satisfies the total sum of the rush current Ip.
The largest value is used for the rush conductivity time T.
5-4-2 Fuse protection
The fuse of branch-circuit protection must use UL class CC, J or T. In the selection, please consider
rush current and rush conductive time.
