Siemens SIRIUS Series Motor Controller, 40A Current, 3 Poles - 3UF7111-1AA01-0


This motor controller is a Compact current and voltage measuring module designed to monitor three-phase motors in industrial installations. It measures TRMS current and voltage up to 690V and provides adjustable overload response from 3A to 40A together with power, energy and frequency measurement functions. The unit snaps onto a Basic motor protection unit and is intended for DIN-rail mounting in environments from -25°C to 60°C.

Features and Benefits:


• TRMS current measurement provides accurate real-time monitoring
• Adjustable 3A to 40A overload response enables tailored protection
• Voltage measurement to 690V supports high-voltage installations
• Power and energy measurement assists consumption and load analysis
• EMC immunity and surge resistance enhance operational stability

Applications


• Suitable for three-phase motor monitoring in manufacturing plants
• Ideal for integration with Basic motor protection units
• Used for power monitoring in motor control centres
• Can be used for frequency and power factor diagnostics
• Suitable for hazardous-location installations with ATEX certification

What input connections are required for current sensing?


It uses straight-through transformers for the main current circuit and accepts external current transformers for range extension.

How does it handle voltage connections for measurement?


Measurement inputs use screw-type terminals and accept finely stranded or solid conductors within 0.25 to 2.5 mm² ranges.

What environmental conditions can it operate in?


It functions at altitudes up to 2,000 m normally and up to 4,000 m with temperature limits

relative humidity during operation is 10 to 95%.

What precision can be expected for current and energy readings?


Current and energy measurement accuracy is specified as ±1.5% in the lower range and ±10% in the extended range under defined operating conditions.

Are there protections against electrical transients?


The module meets surge resistance ratings including 2 kV burst and 1 kV conductor-to-conductor surge as specified for EMC performance.
