Products description

SIEMENS 3RF2230-2AC45 SIRIUS Solid-state Relays, 45mm, 3-Phase for Resistive/Inductive Loads

 

solid-state Relay 3-phase, 30A, operational voltage: 40C, operational voltage: 48-600V, control supply voltage: DC 4-30V 3-phase-controlled cage-clamp-terminal blocking voltage 1200V

 

General Description

Solid-state relays (without heat-sink)

SIRIUS 3RF2 solid-state relays are suitable for surface mounting on existing cooling surfaces. Mounting is quick and easy, involving just two screws. The special technology of the power semiconductor ensures there is excellent thermal contact with the heat sink. Depending on the nature of the heat sink, the capacity reaches up to 88 A on resistive loads.

The solid-state relays are available in 3 different widths:

  • 3RF21 single-phase solid-state relay with a width of 22.5 mm
  • 3RF20 single-phase solid-state relay with a width of 45 mm
  • Three-phase 3RF22 solid-state relay with a width of 45 mm

The 3RF21 and 3RF22 solid-state relays can be expanded with various function modules to adapt them to individual applications.

Version for resistive loads, zero-point switching

This standard version is often used for switching space heaters on and off.

Version for inductive loads, instantaneous switching

In this version the solid-state relay is specifically matched to inductive loads. Whether it is a matter of frequent actuation of the valves in a filling plant or starting and stopping small operating mechanisms in packet distribution systems, operation is carried out safely and noiselessly.

Special Low noise version

Thanks to a special control circuit, this special version can be used in public networks up to 16 A without any additional measures, such as interference suppressor filters. As a result, in terms of emitted interference, it conforms to limit value curve class B according to EN 60947-4-3.

Single-phase solid-state relay with a width of 22.5 mm

With its compact design and a width of just 22.5 mm, which stays the same even at currents of up to 88 A, the 3RF21 solid-state relay offers an ultra small footprint. The logical connection method, with the power infeed from above and load connection from below, ensures a clear and tidy control cabinet.

Single-phase solid-state relay with a width of 45 mm

The solid-state relays with a width of 45 mm provide for connection of the power supply lead and the load from above. this makes it easy to replace existing solid-state relays in existing arrangements. The connection of the control cable also saves space in much the same way as the 22.5 mm design, as it is simply plugged on.

Three-phase solid-state relay with a width of 45 mm

With its compact design and a width of just 45 m, which stays the same even at currents of up to 55 A, the 3RF22 solid-state relay offers an ultra small footprint. The logical connection method, with the power infeed from above and load connection from below, ensures a clear and tidy control cabinet.

The three-phase solid-state relays are available with

  • two-phase control (suitable in particular for circuits without connection to the neutral conductor) and
  • three-phase control (suitable for star circuits with connection to the neutral conductor or for applications in which the system requires all phases to be switched).

Selection notes

When selecting solid-state relays, it is also necessary to know details of the planned design in addition to information about the network, the load and the ambient conditions. The solid-state relays can only conform to their specific technical specifications if they are mounted with appropriate care on an adequately dimensioned heat sink.

Direct mounting of solid-state relays on a mounting plate of sheet steel does not offer sufficient heat dissipation.

The following procedure is recommended:

  • Determine the rated current of the load and the mains voltage
  • Select the relay design and choose a solid-state relay with a higher rated current than the load
  • Determine the thermal resistance of the proposed heat sink
  • Check the correct relay size with the aid of the diagrams
