Contactor relays, size S00, with accessoriesSome accessories (13, 15, 16) are also suitable for 3RH11 coupling contactor relays. StandardsIEC/EN 60947‑1, IEC/EN 60947‑4‑1, IEC/EN 60947‑5‑1 The 3RH1 contactor relays are suitable for use in any climate. They are finger-safe according to IEC 60529. The 3RH1 contactor relays have screw or spring-type terminals. The basic unit contains four contacts with terminal designations according to EN 50011. Contact reliabilityHigh contact stability at low voltages and currents, suitable for solid-state circuits with currents ≥ 1 mA at a voltage of ≥ 17 V. Surge suppressionRC elements, varistors, diodes or diode assemblies (combination of a diode and a Zener diode) can be plugged onto all contactor relays from the front for damping opening surges in the coil. The plug-in direction is determined by a coding device. Note: The OFF-delay times of the NO contacts and the ON-delay times of the NC contacts increase if the contactor coils are attenuated against voltage peaks (suppression diode 6x to 10x; diode assemblies 2x to 6x; varistor +2 to 5 ms). AccessoriesThe accessories for the 3RT1 contactors in size S00 can also be used for the 3RH1 contactor relays, see "Accessories and Spare Parts" в†’ "for SIRIUS 3RT1 Contactors and SIRIUS 3RH1 Contactor Relays". Auxiliary switch blocksThe 3RH1 contactor relays can be expanded by up to four contacts by the addition of snap-on auxiliary switch blocks. The auxiliary switch block can easily be snapped onto the front of the contactors. The auxiliary switch block has a centrally positioned release lever for disassembly. Auxiliary switches according to EN 50011 The 3RH11 contactor relays with 4 contacts with the identification number 40E according to EN 50011 can be extended with auxiliary switch blocks 3RH1911-. GA . . to obtain contactor relays with eight contacts according to EN 50011. The identification numbers 80E to 44E on the auxiliary switch blocks apply to the complete contactors. These auxiliary switch blocks cannot be combined with contactor relays with identification numbers 31E or 22E; these are coded. Auxiliary switches according to EN 50005 All 3RH11 contactor relays with 4 contacts according to EN 50011, identification numbers 40E to 22E, can be extended with auxiliary switch blocks 40 to 02 to obtain contactor relays with six or eight contacts in accordance with EN 50005. The identification numbers on the auxiliary switch blocks apply only to the attached auxiliary switch blocks. Of the auxiliary contacts (integrated plus mountable) possible on the device, no more than 4 NC contacts are permitted. 8-pole contactor relay 3RH12In addition, fully mounted 3RH12 8-pole contactor relays are available; the mounted 4-pole auxiliary switch block is not removable. The terminal designations are in accordance with EN 50011 or IEC 60947-5-1. These versions are built according to special Swiss regulations SUVA and are distinguished externally by a red labeling plate.
