Technical note
■ Service Conditions
1. Normal service conditions
If under ordinary conditions the following normal working
conditions are all satisfied, the AE Series air circuit breaker
may be used unless otherwise specified.
1Ambient air temperature:
A range of max. +40°C to min. –5°C is recommended.
However, the average over 24 hours must not exceed
+35°C.
2Altitude: 2,000 m (6,600 feet) or less
3Environmental conditions:
The air must be clean, and the relative humidify 85% or
less at a max. of +40°C.
Do not use and store in atmospheres with sulfide gas,
ammonia gas, etc.
S ≤ 0.01 ppm, SO ≤ 0.05 ppm, NH

2 2
4Installation condition:
When installing the AE Series air circuit breaker, refer to
the installation instructions in the catalogue and instruc-
tion manual.
5Replacement yardstick :
Approx. 15 years. It is dependent on the environment.
Please refer to "Inspection and Maintenance" section of
this manual.

Guarantee

Guarantee
1. Free guarantee period
The free guarantee period of the product is one year from
the day of purchase.
2. Scope of guarantee
(1) We will repair the product free of charge within the guar-
antee period on condition that it has been used under
the standard working conditions in conformity with the
operating conditions, operating procedures, environmen-
tal conditions and instructions specified in the catalogs,
manuals and caution labels on the product body.
(2) In the following cases, the product will be repaired at
your expense even within the free guarantee period.
• Failure caused by your improper storage or handling,
carelessness or negligence
• Failure caused by inadequacies of installation
• Failure caused by mis-operation or improper modifica-
tion
• Failure caused by external factors due to acts of God,
such as fire and abnormal voltage, and natural disas-
ters, such as earthquake, windstorm and flood
• Failure caused by reasons that could not be foreseen
on the level of science and technology at the time of
delivery
The term "guarantee" used in this section refers to the guaran-
tee only of the delivered product. We are not liable to com-
pensate for any damage induced by the failure of the deliv-
ered product.

2. Special service conditions
In case of special service condition, service life may be-
come shorter in some cases.
1Special environmental conditions
High temperature and/or high humidity
Corrosive gas
2Special ambient temperature
If the ambient temperature exceeds +40°C, the uninter-
rupted current rating will be reduced.
3Special altitude
If it is used at 2,000 m or higher the heat radiation rate is
reduced decreasing the operating voltage rating, continu-
ous current capacity and breaking capacity. Moreover
the durability of the insulation is also decreased owing to
the atmospheric pressure. Apply for further detail.
3. Repair parts supplying period
The supply of the repair parts is warranted for 5 years
after discontinuation of the production. The supply is ter-
minated as soon as the repair parts run out after the 5
years.
