3 3RT, 3RH, 3TB, 3TC, 3TH, 3TK Contactors for Special Applications Contactors with Extended Operating Range 0.7 ... 1.25 x , for Railway Applications 3RT10 motor contactors, 5.5 ... 45 kW ■ Overview DC operation IEC 60947-4-1, EN 60947-4-1 (VDE 0660, Part 102), for requirements according to IEC 60077-1 and IEC 60077-2. The contactors are finger-safe according to EN 50274 (exception: series resistors S0 to S3). The contactors are available with both Cage Clamp and screw connection. The size S00 contactors have Cage Clamp terminals for all connections. The auxiliary conductor and coil terminals of sizes S0 to S3 are all Cage Clamp terminals. Ambient temperature The permissible ambient temperature for operation of the contactors (across the full magnetic coil operating range) is -40 °C to +70 °C. Uninterrupted duty at temperatures > +60 °C reduces the mechanical endurance, the current-carrying capacity of the conducting paths and the switching frequency. Dimensions Attaching resistors increases the width of contactor sizes S0 to S3 (see "Dimensional Drawings"). ■ Function Control and auxiliary circuits The magnetic coils of the contactors have an extended operating range from 0.7 to 1.25 x Us and are fitted as standard with varistors to provide protection against overvoltage. The opening delay is consequently 2 to 5 ms longer than for standard contactors. 3RT10 . .-0LA0 The DC solenoid systems of the contactors are modified (to holding excitation) by means of a series resistor. The size S00 contactors are supplied prewired with a plug-on module containing the series resistor. The varistor is integrated. A 4-pole auxiliary switch block (according to EN 50005) can be fitted additionally. The size S0 to S3 contactors are equipped on the front with an auxiliary switch block with 2 NO + 2 NC contacts. The separate series resistor, which is attached laterally next to the contactor on the 35 mm standard mounting rail, is fitted with connecting cables for mounting onto contactors. A circuit diagram showing the terminals is stuck onto each contactor. One NC of the auxiliary contacts is required for the series resistor function. The selection and ordering data shows the number of additional, unassigned auxiliary contacts. It is only possible to extend the number of auxiliary contacts with size S00. 3/122 Siemens LV 1 T · 2009 © Siemens AG 2009 Mounting U s At ambient temperatures up to 70 °C, the size S00 contactors and contactor relays are allowed to be mounted side by side. The resistor module of the size S0 to S3 contactors must be mounted to the left of the contactor owing to the prefabricated connecting cables. 3RT10 17-2K.4., 3RT10 2.-3K.40 These contactors have an extended operating range from 0.7to1.25xUs; the coils are fitted with varistors as standard. An additional series resistor is not required. Please note: Size S00: it is not possible to mount an auxiliary switch block. Size S0: up to two single-pole auxiliary switch blocks can be mounted. At ambient temperatures > 60 °C ≤ 70 °C, a clearance of 10 mm is required when they are mounted side by side. 3RT10 contactors with contactor control unit, extended operating range Control and auxiliary circuits The magnetic coils of the contactors have an extended operating range from 0.7 to 1.25 x Us and are fitted as standard with varistors to provide protection against overvoltage. The opening delay is consequently 2 ms to 5 ms longer than for standard contactors. 3RT10 ..-.X.40-0LA2 The contactors are energized via upstream control electronics which ensure the coil operating range of 0.7 to 1.25 x Us at an ambient temperature of 70 °C. They are supplied as complete units with a built-on contactor control unit. A varistor is integrated for damping opening surges in the coil. The possibility of mounting auxiliary switches is the same as that for equivalent standard contactors. Mounting At ambient temperatures up to 70 °C, sizes S0 to S3 of these contactor versions are allowed to be mounted side by side. Ambient temperature The permissible ambient temperature for operation of the contactors (across the full operating range of the magnetic coil) is -40°C to +70°C. Uninterrupted duty at temperatures > +60 °C reduces the mechanical endurance, the current-carrying capacity of the conducting paths and the switching frequency. Dimensions Because of the built-on contactor control unit, the height of the size S0 to S3 contactors increases by up to 34 mm (see "Dimensional Drawings").
