5 RT Power Contactors for Switching Motors RT0 contactors, -pole,... 5 HP Overview Sizes S00 and S0, up to 5 HP Connection methods The RT contactors are available with screw connections, spring-type terminals or ring lug terminal connections. Screw terminals Spring-type terminals Ring lug terminal connection These connections are indicated in the corresponding tables by orange backgrounds. IEC , EN , IEC , EN IEC , EN (auxiliary switches) The RT contactors are climate-proof and are suitable and tested for use worldwide. If the devices are used in ambient conditions which deviate from common industrial conditions (EN "Stationary Use, Weather-Protected"), information must be obtained about possible restrictions with regard to the reliability and endurance of the device and possible protective measures. In this case contact our Technical Assistance. RT contactors are finger-safe according to EN The devices with ring terminal lug connection comply with degree of protection IP0 when fitted with the related terminal cover. Auxiliary contact complement Size S00 contactors have an auxiliary contact integrated in the basic unit. The basic units size S0 contain two integrated auxiliary contacts (1 NO + 1 NC). All basic units (excluding coupling contactors) can be expanded with auxiliary switch blocks. For size S0 and higher, complete units with NO + NC are available (terminal designation according to EN 5001). The auxiliary switch block can be removed. A maximum of 4 additional auxiliary contacts can be attached; the auxiliary switch blocks used can be of any version. Of the maximum number of auxiliary contacts possible on the device (integrated plus mountable), four NC contacts are permitted in the case of contactor size S00 and four NC contacts in the case of contactor size S0. In addition, complete units with permanently mounted auxiliary switch block ( NO + NC according to EN 5001) are offered for sizes S00 and S0. Contact reliability If voltages 110 V and currents 100 ma are to be switched, the auxiliary contacts of the RT contactor or RH1 contactor relay should be used as they guarantee a high level of contact reliability. These auxiliary contacts are suitable for solid-state circuits with currents 1 ma at a voltage 17 V. Short-circuit protection of the contactors For short-circuit protection of the contactors without overload relay see "More Information" (pages /0, /). For short-circuit protection of the contactors with overload relay see Chapter 5 "Overload Relays". To assemble motor starters you must select combinations of motor starter protector and contactor as explained in "RA Motor Starters" (see Chapter 6). Motor protection RU1 thermal overload relays or RB0 solid-state overload relays can be fitted to the RT contactors for protection against overload. The overload relays must be ordered separately (see Chapter 5). Ratings of induction motors The quoted rating (in HP) refers to the output power on the motor shaft (according to the motor nameplate). Control supply voltage All contactors are available with AC or DC operation. For contactors of size S0, a UC operating mechanism is also available which allows for operation with both AC (45 to 70 Hz) and with DC. Surge suppression RT contactors can be retrofitted with RC elements, varistors, suppressor diodes or diode assemblies (assembly of diode and Zener diode for short break times) for damping opening surges in the coil. The surge suppressors are plugged onto the front of size S00 contactors. Space is provided for them next to a snap-on auxiliary switch block. The surge suppressors can be plugged onto the front of size S0 contactors. Note: The OFF-delay of the NO contact and the ON-delay of the NC contact are increased if the contactor coils are attenuated against voltage peaks (noise suppression diode 6 to 10 times; diode assemblies to 6 times, varistor and suppressor diode + to 5 ms). S00 and S0 contactors with communication interface The S00 and S0 contactors with communication interface are essential for mounting the SIRIUS function modules for connection to the control system through IO-Link or AS-Interface (see page /81 and /85). Further information on IO-Link and AS-Interface can be found in Chapter "Industrial Communication". /5

The identification numbers according to EN 5001, e. g. 11E, apply to the basic device plus mounted auxiliary switch. All contactors of size S00 with one auxiliary contact (identification numbers 10E or 01) and the contactors with 4 main contacts can be expanded into contactors with to 5 auxiliary contacts using auxiliary switch blocks with the identification numbers 40 to 04 (in the case of contactors with 4 main contacts: 1 to 4 auxiliary contacts) according to EN Of the auxiliary contacts (integrated plus mountable) possible on the device, no more than four NC contacts are permitted. Single- or -pole auxiliary switch blocks with connection options from above or below enable easy and clearly arranged wiring especially for the installation of network access junctions. These auxiliary switch blocks are offered only with screw terminals. If the installation space is limited in depth, -pole auxiliary switch blocks (screw or spring-type terminals and ring terminal lug connection) can be attached laterally for use on the right or on the left. The solid-state compatible RH9 1.-1NF.. auxiliary switch blocks for contactors of size S00 include enclosed contacts. They are suitable in particular for switching small voltages and currents (hard gold-plated contacts) and for operation in dusty atmospheres. The NC auxiliary contacts are not mirror contacts. All the previously mentioned auxiliary switch variants can be snap-fitted onto the front of the contactor. The auxiliary switch block has a centrally positioned release lever for disassembly. Ident.

If the installation space is limited in depth, -pole auxiliary switch blocks (screw or spring-type terminals and ring lug terminal connection) can be attached laterally for use on the right or on the left. The auxiliary switch blocks attached to the front can be disassembled with the help of a centrally arranged release lever; the laterally attached auxiliary switch blocks are easy to remove by pressing on the checkered surfaces. The terminal designation of the individual auxiliary switch blocks corresponds to EN or EN 5001, that of the complete contactor with auxiliary switch block NO + NC corresponds to EN The laterally mountable auxiliary switch blocks according to EN 5001 can be used only when no 4-pole auxiliary switch blocks are snapped onto the front. As auxiliary contacts 1 NO + 1 NC are already integrated in the basic device, mounting according to EN 5001 is permitted only on the right of the device. The front 1- or -pole auxiliary switch blocks with connection option from below or above have fixed location identifiers. These auxiliary switch blocks are available only with screw terminals. If the 4-pole and solid-state compatible auxiliary switch blocks are used, the location identifiers on the basic device must be noted. Two enclosed contacts are available with the RH9 11-.NF11 solid-state compatible auxiliary switch block, which can be attached to the front. The RH9 1-DE11 laterally mountable, solid-state compatible auxiliary switch block also contains enclosed contacts (1 NO + 1 NC). The enclosed contacts are suitable in particular for switching small voltages and currents (hard gold-plated contacts) and for operation in dusty atmospheres. The front NC auxiliary contacts are not mirror contacts. A maximum of 4 auxiliary contacts can be attached; the auxiliary switch blocks used can be of any version. Of the auxiliary contacts (integrated plus mountable) possible on the device, no more than four NC contacts are permitted however. For 4-pole contactors see RT and RT5. Contactor, size S0, with 4-pole auxiliary switch block A diverse range of auxiliary switch blocks is available for various applications. One 4-pole auxiliary switch block (screw or spring-type terminals and ring lug terminal connection) can be snapped onto the front of the contactors. When the contactors are switched on, the NC contacts are opened first and then the NO contacts are closed. /7
