IEC Overload Relays GENERAL SIRIUS 3RU11 Bimetallic Class 10 Overload Relays Description 3RU11 overload relays belong to the new generation of SIRIUS 3R control products. The 3RU11 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. 3RU11 overload relays cannot be mounted onto 3TF contactors. The 3RU11 overload relays are available in four distinct frame sizes up to 100A. The selection charts in this catalog refer to the different frame sizes by their catalog numbers, i.e. 3RU111, 3RU112, 3RU113, and 3RU114. The sixth character in the part number designates the frame size. This “size number” is consistent with, and matches up to, the same four frame sizes of the other IEC products in this catalog. However, it is important to note that other SIRIUS 3R catalog versions in circulation throughout the world refer to these four sizes as S00, S0, S2, and S3 respectively. It is a possibility that these four frame size references (S00, S0, S2, and S3) may appear on product labels as well. 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. Ambient conditions Thanks to the newly integrated bimetal and continuous temperature compensation, these devices can be used without derating at an ambient temperature of up to 60°C (140°F). Use up to 70°C (158°F) is possible with derating. (See Siemens Industrial Control Products Catalog - CPPC-06000). Auxiliary contacts The overload relays are equipped with a NC contact for de-energizing the contactor and a NO contact for signalling an overload trip. The breaking capacity of the switching contacts is very high so that the contactor coils can be switched directly. Trip class The 3RU11 overload relays are designed in accordance with trip class 10, i.e. trips in less than 10 seconds at 6 times the trip current setting (FLA). 1 2 3 4 5 6 1 2 3 5 6 7 8 4 9 7 8 9 Equipment identifying marker Manual/automatic RESET selector switch STOP button Complete Catalog No on front of device Switch position indicator and TEST function Transparent cover, sealable (secures the current setting screw, TEST function and manual/automatic RESET position) Current setting dial Terminal for contactor coil (when mounted on contactor) Terminal for contactor aux. contacts (when mounted on contactor) 3RU111 Overload Relay Phase failure sensitivity A phase failure sensitivity function is integrated in order to provide increased protection in the event of a phase failure, i.e. faster tripping in the event of a single-phase condition.
