Solid-State Switching Devices for Resistive Loads
Solid-State Relays
SIRIUS 3RF22 solid-state relays,
three-phase, 45 mm
4/74
Siemens IC 10 · 2011

■ Overview
With its compact design and a width of just 45 mm, 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 tidy installation in the control cabinet.
Important features:
• LED display
• Variety of connection methods
• Plug-in control connection
• Degree of protection IP20
• Zero-point switching
• Two- or three-phase controlled
■ Technical specifications
1)
These products were built as Class A devices. The use of these devices in
residential areas could result in lead in radio interference. In this case
these may be required to introduce additional interference suppression
measures.
2)
If two different conductor cross-sections are connected to one clamping
point, both cross-sections must lie in the range specified. If identical cross-
sections are used, this restriction does not apply.
