Switches

Motor, load and control switches for hazardous areas
These switches from R. STAHL perform various roles in hazardous areas: Load and motor switches are used as motor or main switches and control switches are used as EM-STOP switches. They are suitable for rated voltages of up to 690 V AC and rated operational currents of up to 180 A.

R. STAHL's explosion-protected switches must be built into enclosures with Ex e type of protection, and are designed for a number of different functions: The load and motor switches fulfil the requirements for use as both motor switches and main switches. The control switches are used as EM-STOP switches and can be set to either the latching or spring-return position as the customer wishes. Our switches are designed for rated operational currents of up to 180 A and rated operational voltages of up to 690 V AC.

  • Load and motor switches in the form of isolator and main switches
  • EM-STOP control switches with latching and spring return function
  • For installation in enclosures with Ex e type of protection
