Product Features

  • Standardized components ensure universal compatibility, significantly reducing spare parts inventory and replacement costs.
  • Anti-arc design effectively suppresses the spread of fault arcs, enhancing operational safety.
  • Convenient expansion; no modifications to the main cabinet are required, and functional units can be added as needed.
  • Fully enclosed busbar compartment design isolates external interference, reducing the risk of fault propagation.
  • Adaptable to harsh operating conditions, possessing excellent temperature resistance, moisture resistance, and electromagnetic interference resistance.

Operating Conditions

  • Ambient Temperature: -5°C to +40°C, with a 24-hour average ≤+35°C.
  • Atmospheric Conditions: Clean air with relative humidity ≤50% at +40°C. Higher humidity is permitted at lower temperatures (e.g., 90% at +20°C), but temperature variations may occasionally cause condensation.
  • Altitude: ≤2000m.
  • Transport & Storage Temperature: -25°C to +55°C, with short-term (≤24h) peaks up to +70°C. The equipment shall sustain no irrecoverable damage at these limits and shall operate normally under standard conditions. Note: For applications exceeding the above conditions, please consult our company for customization.
