Technical information
Arc space
When a short-circuit current is interrupted, discharged hot gas blows out from the exhaust port of the arc chute chamber,
so provide a clearance as shown in the following table.
Service conditions
1. Normal service condition
Under ordinary conditions that the following normal working
conditions are all satisfied, the AE V Series air circuit breaker
may be used unless otherwise specified.
1. Ambient temperature
A range of +40°C max. to -5°C min. is recommended.
And the average over 24 hours must not 35°C.
2. Altitude
2000 m (6600 feet) or less
3. Environmental conditions
The air must be clean, and the relative humidity must be 85%
or less at +40°C max. Do not use and store the product in
atmospheres with sulfide gas and ammonia gas etc.
(H

4. Installation conditions
When installing the AE V Series air circuit breaker, refer to the
installation instructions in the catalogue and instruction manual.
5. Storage temperature
A range of max. +60°C to min. -20°C is recommended to
bestored.
And the average over 24 hours must not 35°C.
6. Guideline for replacement
Within approx. 15 years. Please refer to the instruction manual.
2. Special service conditions
In case of special service condition, the service life may become
shorter in some cases.
1. Special environmental conditions
High temperature and/or high humidity
Corrosive gas
2. High ambient temperature
If the ambient temperature e40°C, the uninterrupted
current rating will be reduced. Since the derating value is
different depending on the applicable standard, refer to
page 37.
3. High altitude
Since the heat radiation rate is reduced for use at the 2000 m
or higher, accordingly the operating voltage, continuous
current capacity, and breaking capacity are derated.
Moreover, the insulation durability is also decreased owing
to the atmospheric pressure.
Please inquire us for further details.

(1) The above table shows the maximum rated current per each ambient temperature for drawout type breaker with vertical connection (at brandnew product), when breaker and bus bar are installed in open air.
(2) Connection bus bar is according to IEC 60947-1. As for ambient temperature exceeding 60°C, please inquire us.
(3) The above table shows the maximum rated current at the ambient temperature.
(4) The above table shows the values calculated by the values measured under the test conditions specified in the IEC 60947-2, which are not actual values. With the circuit breaker mounted to the panel,
verify the values under the test conditions specified in the IEC 61439-1 and others.
Note) Set the proper values using the assembly verification in consideration of the influence of the heat of other devices in the panel, heat capacity of the connecting conductor, supply and exhaust, and air
convection in the panel.
In case extension, display (DP1) are attached, the following derating values shown in this table are applied.
