GENERAL
Sigma SFA/SDA series intelligent Air Circuit Breakers are suitable
for use in commercial buildings or industrial plants where safety
and reliability of power supply is an important requirement.
Main Features;
• Fixed and Drawable versions
• Rated current from 630A to 6300A AC and rated voltage of 690 V.
• Short Circuit Breaking Capacity 80kA~120kA (effective value);
• Rated working voltage 690V AC
• Three or four poles;
• Microprocessor controlled intelligent trip unit for all round protection
• Manual or motor operated stored energy drive mechanism for direct or remote actutation.
• Ambient temperature: -5 ~ +40, and average temperature in 24 hours below +35 (except for special orders)
• Comply with EN 60947-2 and VDE 0660.
Environment conditions For Operation and Installation
• Altitude should be less than 2000m.
• Relative humidity: not exceeding 50% at the maximum ambient temperature. higher humidity would be permitted, but the
lowest average temperature in a month not exceeding +35°C during the most moist moth, and the maximum monthly average relative
humidity not exceeding 90% in that month, and giving consideration the dews on the goods surface, which would appear due to
temperature change.
• Pollution degree 3 grade.
• The breakers used on ships can operate reliably under normal vibration.
• The breaker should be installed in compartment of switch - board and door frame should be fixed additionally. Protection grade
is up to IP40

The panel here in belongs to the circuit breaker of four poles,
If the breaker is of three poles, the mark IN in item 9 indicating
current of neutral phase will disappear. Other than the type
M intelligent controller with voltage indication, the other one
without voltage indication is also available (there aren't items 3,
4, 5 and 6 on the panel in this case).
