Overview
Fuseless load feeders
Fuseless load feeders are device combinations comprising a 3RV motor starter protector for
overload and short-circuit protection and a 3RT contactor for normal switching. The SIRIUS
portfolio features two different configuration options for fuseless load feeders.
● 3RA2 tested pre-assembled complete devices (sizes S00 to S2 only)
● Tested combinations of individual devices
The modular standard components in the SIRIUS modular system are ideally matched and
support the simple configuration of fuseless load feeders. The load feeders are also
available as 3RA2 complete devices.
Both options are characterized by the following features.
● Type of coordination 1 or 2
● Rated control supply voltage
● Mounting on busbar or DIN rail
● Screw or spring-loaded connection
