Panel Accessories


The mechanical thermostat and hydrostats are used for controlling heating and cooling equipment, filter fans or signal devices. The thermostat registers the surrounding air and can switch both inductive and resistive loads via snap-action contact.

  • Adjustable temperature
  • High switching capacity
  • Small hysteresis
  • Terminals easily accessible
  • Clip fixing
  • Change-over contact
