ARS 00/100

ARS vertical fuse switch disconnectors are designed for the distribution of electricity and protection against short circuits and overloads in three phase alternative current circuits. They are intended for direct installation on horizontal or vertical busbar systems. Their modern and compact design give much saving of space in substations and distribution boards. Each type is suitable for top cable terminal connection when installed on horizontal busbar system. Removal of the fuse link provides clearly noticeable, large isolating distance in the circuit. ARS vertical fuse switch disconnectors have making capacity in utilization categories: AC-21B, AC-22B, AC-23B. Easy installation of earthing devices is another advantage.

ARS vertical fuse switch disconnectors are designed to perform the following functions:

protection
distribution
earthing
switching
touch protection.

All technical parameters required by standards and growing requirements of the market have been taken into account in design (conformity with EN 60947-3). Several advices and remarks from business partners have been also taken into account.

Operating conditions

to be installed in the room free of any dust, aggressive or explosive gases,
altitude up to 2000 meters above sea level,
outdoor - in cabinets with protection degree > IP 34,
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%,
relative humidity of the air should not be higher than 50% at temperature of +40°C.
