PBS 00/100 mm

PBS fuse rails are designed for the distribution of electricity and protection against short circuits and overloads in three phase alternative current circuits with maximum operating voltage of 690 V. They are intended for direct installation on horizontal or vertical bus bar system. Due to their modern and compact design installing is easy and gives much saving of space in substations and distribution boards. All technical parameters required by standards and requirements of the market were taken into account during design (conformity with EN 60269-1, EN 60269-2, IEC 60269). Several advices and remarks from business partners were also taken into account.

• Designed for installation on to 185 mm busbar system, (size 00-SM, 2, 3)
• Removal of the fuse link provides clearly noticeable, large isolating gap in the circuit
• Fuse rails width: size 00/100, 00-SM - 50 mm
• Possible installation of various earthing devices

• To be installed in the room free of any dust, aggressive or explosive gases
• Ambient temperature from -25°C to +55°C – but in case of use of disconnectors in temperature from +41°C to +45°C
• Current value Ith should be reduced by 5% and within temperature range of +46°C to +55°C current value Ith should be reduced by 10%
• Altitude up to 2000 meters above sea level
• Relative humidity of the air should not be higher than 50% at temperature of +40°C
• Outdoor – in cabinets with protection degree > IP 34
