Overview
Three-phase solid-state relays (without heat sink) 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 tidy installation in the control cabinet.
Important features:
•LED display
•Variety of connection methods
•Plug-in control connection
•Degree of protection IP20 (with ring terminal lug connection IP00)
•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 one of the ranges specified.
