0.45-0.63 Amp Siemens Sirius 3RU111 Bimetallic Class 10 Overload Relay with Screw Terminals

3RU111 overload relays belong to the new generation of SIRIUS 3R control products. The 3RU111 overload relays replace the highly successful 3UA5 and 3UA7 devices. Outstanding features of the new overload relays include long term stability and long service life. The overload relays are optimally matched, both electrically and mechanically, to the 3RT10 contactors. They can also be mounted as a single unit with the use of a separate mounting bracket. 3RU111 overload relays cannot be mounted onto 3TF contactors.

Application:
3RU11 overload relays provide overload protection for three-phase inductive motors with rated currents of up to 100A (75HP, AC-3, 480V). They are used in conjunction with 3RT10 contactors to form motor starters.
