3 3RH, 3TH Contactor Relays 3RH14 latched contactor relays, 4-pole ■ Overview AC and DC operation IEC 60947, EN 60947 (VDE 0660). The terminal designations comply with EN 50011. The contactor coil and the coil of the release solenoid are both designed for uninterrupted duty. The number of auxiliary contacts can be extended by means of auxiliary switch blocks (up to 4 poles). 3/136 Siemens LV 1 T · 2009 © Siemens AG 2009 RC elements, varistors diodes or diode assemblies can be fitted to both coils from the front for damping opening surges in the coil. The contactor relay can also be switched on and released manually (for minimum actuating times, see page 3/134).
■ Overview AC and DC operation IEC 60947 and EN 60947 (VDE 0660). The 3TH42/3TH43 contactor relays are suitable for use in any climate. They are finger-safe according to EN 50274. Terminal designations according to EN 50011 In terms of their terminal designations, identification numbers and identification letters, the 3TH42/3TH43 contactor relays conform to the standard EN 50011 for "Specific contactor relays". ■ Technical specifications Contactors Permissible mounting position Type 3TH42/3TH43 The contactors are designed for operation on a vertical mounting surface. AC operation DC operation Upright mounting position AC and DC operation Special version required Positively-driven operation in contactor relays with 8 and 10 contacts 3TH42/3TH43: Explanations: Yes, the contactor relays comply with the conditions for positively-driven operation acc. to: ZH 1/457 EN 60947-5-1, Appendix L SUVA © Siemens AG 2009 3RH, 3TH Contactor Relays 3TH4 contactor relays, 8- and 10-pole ■ Function Contact reliability High contact stability at low voltages and currents thanks to the use of moving double-break contacts, suitable for solid-state circuits with currents ≥1 mA for voltages at 17 V. Make-before-break contacting The 3TH42/3TH43 contactor relays are available in versions with make-before-break contacting (make-before-break between1NO and 1NC). The make-before-break time is approximately 1 ms. This is not sufficient to cause another contactor to close. If the make-before-break conducting paths are connected in series, a fleeting contact element is created; the wiping time is approximately 1ms. Surge suppression The 3TH42/3TH43 contactors can be equipped with RC elements, varistors, diodes or diode assemblies (combination of a diode and a Zener diode) for damping opening surges. The surge suppressors can be mounted directly on the coil (see "Accessories"). Note: The OFF-delay times of the NO contacts and the ON-delay times of the NC contacts increase if the contactor coils are damped against voltage peaks (noise suppression diode 6 to 10 times; diode assembly 2 to 6 times, varistor +2 to 5 ms). 360° 5 * " % % = 5 * % ! = 30° 30° NSB0_00649 There is positively-driven operation if it is ensured that the NC and NO contacts cannot be closed at the same time.
