WebThey provide accurate and reliable protection to motors against overload as per CLASS 30. They also offer protection against single phasing and unbalanced voltages. If single-phase AC or DC loads are to be protected by the 3UA / 3UC thermal overload relays, all three bimetal strips must be heated. Webprovide a maximum trip rating of 125% of minimum motor amperes for 40˚C motors (service factor 1.15). For other motors (service factor 1.0), select the next lower listed heater catalog number within the designated table which provides a maximum trip rating of approximately 115%. Overload relays do not provide protection against short circuits.
WebBimetal Overload Relays Overload protection can be accomplished with the use of a bimetal overload relay. This component consists of a small heater element wired in series with the motor and a bimetal strip that can be used as a trip lever. The bimetal strip is made of two dissimilar metals bonded together. The two metals have WebBimetal overload relays. Motor protection is one of the central tasks of the electrical equipment of any machine. The bimetal relays of the Eaton Moeller series offer the right solution for any application.
