Series 8570/21 20 A wall-mounting sockets

R. STAHL Series 8570/21 SolConeX sockets constitute explosion-protected electrical equipment. They are approved for use in hazardous areas that are classified for the division or zone according to NEC 505.

The load disconnect switch, with a mechanical locking device and a handle that can be locked in the 0 or I position, is an additional safety feature.

  • Different voltage ranges according to EN 60309
  • Large temperature range of use
  • High mechanical impact and shock resistance
  • Perfect protection against penetration of liquids and dusts
  • 3D data for download on the website
  • Appropriate Series 8570/22 plug
