PROFINET High Feature for the 3RW55 soft starter line
The 3RW5950-0CH00 is a SIRIUS communication module that adds a PROFINET High Feature interface with an integrated two-port switch to the 3RW55 soft starter family. It mounts via screw fixing in any orientation, measuring 28 mm wide by 126 mm high by 82 mm deep — a compact footprint that fits alongside the soft starter on the DIN rail without stealing panel width from adjacent motor starters.
Temperature derating and environmental limits
Rated for operation from -25 °C to +60 °C, but the basic unit must be derated above 40 °C — a factor to account for when the module sits in a warm cabinet near the soft starter's heat sink. Storage and transport tolerance spans -40 °C to +80 °C, with IEC 60721 class 3K6 conditions during operation (no ice formation, occasional condensation) and class 1K6 during storage. Installation altitude reaches 5 000 m above sea level, with derating starting at 1 000 m per the catalog — relevant for high-altitude panel builds where air density affects cooling.
Active production and compliance documentation
Substance prohibitance is declared effective 02/11/2019, and the module complies with IEC 60721 environmental classifications for storage, transport, and operation — covering RoHS/REACH-type substance restrictions and mechanical durability to class 3M6 during operation.
