Front protection cover of thermal overload relays
A sealable protection cover is available to protect the overload relay, when fixed in place, from all possibly adjuster tampering and involuntary activation of the Reset and Stop buttons.
  

Clear identification of thermal overload relay manual or automatic resetting
The RF38 thermal overload relay is supplied configured for manual resetting.
By breaking the two tabs, the Reset button can be rotated to automatic resetting.
The broken tabs and the index indicator provides for immediate and distinct identification of the selected configuration.
Effortless thermal overload relay link

The complete overload relay fixing is obtained with one single operation and without other connections.
