• Units with integrated heat sink, "ready to use"
• Compact and space-saving design
• Reversing contactors with integrated interlocking
■
Application
Use in load feeders
There is no typical design of a load feeder with solid-state relays
or solid-state contactors; instead, the great variety of connection
methods and control voltages offers universal application
opportunities. SIRIUS solid-state relays and solid-state
contactors can be installed in fuseless or fused feeders, as
required.
See Configuration Manual "Configuring SIRIUS – Selection Data
for Fuseless and Fused Load Feeders",
.
