200-690 V soft starter with ATEX and trip class flexibility
The Siemens 3RW5527-1HA06 is a soft starter covering a 200-690 V supply range, with ATEX and IECEx certification for use in potentially explosive atmospheres.
Fieldbus, monitoring, and special functions
Supports PROFIBUS, Modbus RTU, Modbus TCP, and EtherNet/IP, plus PROFIenergy for coordinated energy management on PROFINET networks. Analog output configurable as 4-20 mA or 0-10 V for feeding motor current or torque to a PLC or panel meter. Built-in pump ramp down, breakaway pulse for high breakaway torque, DC braking, and combined braking — the breakaway pulse is useful for conveyors or crushers that need a torque spike to unstick the load before ramping.
Mounting and environmental limits
Dimensions are 306 mm high, 185 mm wide, 203 mm deep — screw terminal connections, with 100 mm clearance required above and 75 mm below for airflow; side clearance is 5 mm, forward 10 mm, backward 0 mm (wall-mountable).
Carries CE, UL, and CSA approvals, plus ATEX and IECEx for hazardous locations — the ATEX marking means it can be installed in Zone 1 or Zone 2 gas groups, subject to the installation code. Accuracy Class 5 per IEC 61557-12 for the integrated metering function; service factor 1.15 allows 15 % continuous overload above nameplate current.
