NewTrend · thermal overload relay
Product overview
NewTrend R2-D23 is a thermal overload relay for AC motor overload and phase-failure protection. Three adjustable current ranges cover 23–32A, 28–36A and 30–40A. It provides temperature compensation, a test button, release indication and manual or automatic reset. Plug-in mounting or independent installation with the corresponding mounting base is supported.
