Application
 

PBS vertical fuse rails, fitted with fuse links, are used to protect electrical circuits against the effects of overloads and short circuits, and are designed for connecting loads in three-phase circuits. They are designed for installation on busbars as three-phase vertical units, thereby achieving significant space savings in the switchgear compared to classic fuse bases installed on panels. The design takes into account all technical parameters compliant with standards (PN-EN 60269-1, PN-EN 60269-2) and the growing demands of the market.

 

Operating conditions
 

  • Environments free from dust, corrosive or explosive gases
  • Ambient temperature from -25°C to +55°C – when using bases at temperatures between +41°C and +45°C, theIth current value must be reduced by 5%, and in the temperature range from +46°C to +55°C, theIth current value must be reduced by 10%
  • At altitudes up to 2000 m above sea level
  • Relative humidity should not exceed 50% at a temperature of +40°C
  • Outdoors – in enclosures with a degree of protection > IP34
