Load disconnect switch

Robust, Ex-protected load and motor switches
R. STAHL's robust load and motor switches can be used as mains connection switches for power distribution systems and motor circuits in hazardous areas. They have a switching capacity of AC-3 or AC-23 for switching motors. The standard variants are designed for rated operational currents of up to 80 A; versions with rated operational currents of up to 630 A are available on request.

R. STAHL's load and motor switches are housed in a robust enclosure, which can be made from either glass-fibre-reinforced polyester resin or sheet steel. They comply with the requirements of IP66. The practical rotary actuator, which comes in a choice of either black or red and yellow, can be padlocked as an additional safety net. It can be used to switch power distribution systems and, with AC-3, AC-23, DC-1 and DC-13 switching capacity, motor circuits too. The load disconnect switches also has isolation functions in accordance with IEC/EN 60947-3. The standard variants are suitable for rated operational currents of up to 80 A; rated operational currents of 16-630 A are available on request.

  • Large, padlockable rotary actuator in black or yellow/red for enhanced safety
  • Robust enclosures made from glass-fibre-reinforced polyester resin or sheet steel, IP66
  • Isolating functions (IEC/EN 60947-3), AC-3, AC-23, DC-1 and DC-13 switching capacity (DIN VDE 0660, Part 107, IEC/EN 60947-3)
