Overview
Single-phase solid-state relays (without heat sink) 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 is as space-saving as the
22.5 mm design, as it is simply plugged on.

Technical specifications
1)
If two different conductor cross-sections are connected to one clamping
point, both cross-sections must lie in one of the ranges specified.
