Semiconductor relay 22.5mm, 20A - Magnet contactor 15...24VDC 3RF2120-2AA02

Semiconductor relay 22.5mm, 20A - Magnet contactor 15...24VDC 3RF2120-2AA02 – Siemens – 4011209574052: Semiconductor relay 22.5mm, 20A 3RF2120-2AA02 Rated control supply voltage Us at DC 15 ... 24V, Type of voltage for actuation DC, Rated operational current Ie at AC-1, 400 V 20A, Suitable for series installation, Number of auxiliary contacts as NO 0, Number of auxiliary contacts as NC contact 0, connection type main circuit spring-loaded connection, number of NC contacts as main contacts 0, number of NO contacts as main contacts 1, solid-state relay, 1-phase 3RF2 overall width 22.5 mm, 20 A 24-230 V / DC 24 V spring-loaded connection SIRIUS 3RF21 solid-state relay for switching ohmic/inductive loads, e.g. B. from radiators or valves in a bottling plant. The devices switch wear-free and silently and are therefore ideal for noise-sensitive areas (offices, hospitals). They are extremely reliable even at high switching frequencies. The compact design saves space on the cooling surface. The solid-state relays can also be expanded with the standardized 3RF29 function modules for a variety of applications by simply clicking on them. The devices are approved worldwide (eg IEC and UL/CSA). The semiconductor relays are available as 1-phase devices in two widths or as 3-phase devices. They are available for different outputs and rated operating voltages. Designed for AC or DC operation, they are available with screw, spring-loaded or ring cable lug connections. In addition to the 3RF29 function modules, control plugs and terminal covers are also available as accessories. Simple, efficient, always up-to-date - the SIRIUS modular system.
