RF38 features FRONT PROTECTION COVER OFTHERMAL OVERLOAD RELAYS CLEAR IDENTIFICATION OF THERMAL OVERLOAD
RELAY MANUAL OR AUTOMATIC RESETTING A sealable protection cover is
available. When fitted on to therelay front, it precludes allpossible adjuster tampering and
involuntary activation of the
“Reset” and “Stop” buttons of thethermal overload relay. The RF38 thermal
overload relay is suppliedconfigured for manualresetting. By breaking
the two tabs, the “Reset”
button can be rotated to automatic resetting. The broken tabs and the index indicator providesfor immediate and distinct identification of the
selected configuration. FIXING EASE OF THE THERMAL
OVERLOAD RELAY SEALABLE RELAY COVER A handy closing flap
feature excludes anytampering of the thermaloverload relay adjuster. While the thermal overloadrelay is being linked to thecontactor, its auxiliary contactfits on and connects to the coil
terminal by rigid terminal.
Complete relay fixing is done ina single operation, without theneed of other connections.
