9 / 70 page 3RT, 3TB, 3TF Contactors for Switching Motors 3RT10 contactors, 3-pole, 3 ... 250 kW 3/9 Siemens LV 1 · 2006 Contactors with solid-state operating mechanism The magnetic coil is supplied selectively with the power required for reliable switching and holding by series-connected control electronics. • Wide voltage range for the control supply voltage Us: Compared with the conventional operating mechanism, the solid-state operating mechanism covers an even broader range of control supply voltages used worldwide within one coil variant. For example, the coil for UC 200 to 277 V (Us min to Usmax) covers the voltages 200-208-220-230-240- 254-277 V used worldwide. • Extended operating range 0.7 to 1.25 x Us: The wide range for the rated control supply voltage and the additionally allowed coil operating range of 0.8 x Us min to 1.1 x Usmax results in an extended coil operating range of at least 0.7 to 1.25 x Us, within which the contactors will operate reliably, for the most common control supply voltages of 24, 110 and 230 V. • Bridging temporary voltage dips: Control voltage failures dipping to 0 V (at A1/A2) are bridged for up to approx. 25 ms to avoid unintentional tripping. • Defined ON and OFF thresholds: For voltages of 0.8 x Us min and higher the electronics will reliably switch the contactor ON, and as of 0.5 x Us min it is reliably switched off. The differential travel in the switching thresholds prevents the main contacts from chattering as well as increased wear or welding when operated in weak, unstable networks. This also prevents thermal overloading of the contactor coil if the voltage applied is too low (contactor does not close properly and is continuously operated with overexcitation). • Low control power consumption when closing and in the closed state. Electromagnetic compatibility (EMC) The contactors with solid-state operating mechanism comply with the requirements for operation in industrial installations. • Interference immunity - Burst (IEC 61000-4-4): 4 kV - Surge (IEC 61000-4-5): 4 kV - Electrostatic discharge, ESD (IEC 61000-4-2): 8/15 kV - Electromagnetic field (IEC 61000-4-3): 10 V/m • Emitted interference - Limit value class A according to EN 55011 Note: When used with converters, the control cables must be routed separately from the load cables of the converter. Indication of remaining lifetime (RLT) Main contactor contacts are working parts which must be replaced in good time when the end of their service life has been reached. The degree of contact erosion and thus the electrical endurance (= number of operating cycles) depends on the loading, utilization category, duty type, etc. Routine checks/visual inspections by the service personnel are needed in order to monitor the state of the main contacts. The "remaining lifetime indication" function takes over this task. It does not count the number of operating cycles – which does not provide information about contact erosion – but instead electronically identifies, evaluates and stores the actual progress of erosion of each one of the three main contacts, and outputs a warning when specified limits are reached. The stored data are not lost even if the control supply voltage for A1/A2 fails. After replacement of the main contacts, measurement the remaining lifetime must be reset using the "RESET" button (hold down RESET button for about 2 seconds using a pen or similar tool). Advantages: • Signaling through relay contact or AS-i when remaining lifetime is 20 %, i.e. contact material wear is 80 % • Additional visual indication of various levels of erosion by means of LEDs on the laterally mounted solid-state module when remaining lifetime is 60 % (green), 40 % (orange) and 20 % (red) • Early warning to replace contacts • Optimum utilization of contact material • Visual inspection of the condition of contacts no longer necessary • Reduction of ongoing operating costs • Optimum planning of maintenance measures • Avoidance of unforeseen plant downtimes 3RT1. ..-.N version: for 24 V DC PLC output 2 control options: • Control without an interface directly through a 24 V DC/ 30 mA PLC output (EN 61131-2). Connection by means of 2-pole plug-in connection. The screwless spring- operated connector is part of the scope of supply. The control supply voltage which supplies the solenoid operating mechanism must be connected to A1/A2.
