Product Description

ARW1 Environment of Use

The temperature of the surrounding air is -40°C to +40°C; the average value of 24h does not exceed +35°C, and the lower limit of the temperature of the surrounding air is -40°C (except for special declarations).

The altitude of the general type shall not exceed 2000m. Altitudes above 2000m shall be used with reduced capacity, and the plateau type shall not exceed 5000m.

At a maximum temperature of +40°C, the relative humidity of the air shall not exceed 50%. At lower temperatures, a higher relative humidity may be permitted, for example, 90% at 20°C.

Pollution class: Class 3

Protection class: IP30

Frequently Asked Questions (FAQ)

What is the operating temperature range for the ARW1 circuit breaker?
The surrounding air temperature should remain between -40°C and +40°C. The 24-hour average temperature must not exceed +35°C, with the minimum operational limit set at -40°C.
Are there specific altitude limitations for ARW1 installations?
Under standard conditions, the altitude should not exceed 2000m. If installed above 2000m, the unit must operate with reduced capacity. The custom plateau-designed models can support up to 5000m max.
What humidity conditions are permitted during operation?
At a peak ambient temperature of +40°C, the relative humidity of the surrounding air must not exceed 50%. A higher relative humidity value (e.g., up to 90% at 20°C) is allowable under lower temperatures.
What are the key ratings for the ARW1-6300 model?
The ARW1-6300 model has a frame size current of 6300A, supporting rated current options of 4000A, 5000A, and 6300A. It features a rated ultimate short-circuit breaking capacity (Icu) of 120KA at AC400V.
What installation methods are supported by the ARW1 series?
The ARW1 air circuit breaker is highly versatile and supports both fixed type and draw-out type installation methods to fit different switchgear configurations.
What protection and pollution categories does the ARW1 fall under?
The ARW1 series air circuit breaker offers an IP30 protection class rating and is certified for use in Category 3 pollution environments.
