Standards in compliance

• IEC 60947-1 and GB 14048.1——Low-voltage switchgear and
control equipment: General
• IEC 60947-2 and GB 14048.2——Low-voltage switchgear and
control equipment: Low-voltage circuit breaker
• IEC 60947-4-1 and GB 14048.4——Low-voltage switchgear and
control equipment: Electro-mechanical contactor and motor
starter
• GB/T 14597——Climatic environmental conditions at different
altitudes for electrical product
• GB/T 2423.1——Environmental test of electrical and electronic
product
• GB/T 20626.1——Plateau electrical and electronic products
under special environmental conditions Part 1: General techni-
cal requirements
Normal operation, installation and transportation con-
ditions
• The electrical and mechanical characteristics are suitable for
ambient temperature of -25°C - +70°C with 24-hour average
values equal to or below +35°C. When above +55°C, derating
is needed for use. See Derating Factor Table.
• The altitude should not exceed 5000m at the installation
site. When higher than or equal to 2000m, the electrical
performance of the circuit breaker needs to be corrected;
• With the maximum temperature at +40°C, the relative air
humidity does not exceed 50%. A higher relative humidity (RH)
is allowed at a lower temperature, such as 90% RH when at
20°C. Special measurement should be taken for occasional
condensation due to temperature changes.
• Pollution level: 3;
• Protection degree: IP40 when the circuit breaker is installed
inside cabinet cubicles and the door escutcheon is installed
• Utilization category: B;
• Mounting category: IV for the circuit breaker's main circuit and
the power supply transformer's primary coil, and III for the
remaining auxiliary circuits and control circuits;
• The vertical inclination does not exceed 5° during mounting;
• Transportation and storage temperature:-25°C - +85°C.
