The Siemens 3UF7122-1AA01-0 is a sophisticated current/voltage measuring module designed for the protection of centrifugal pumps in hazardous environments. This module is part of the SIRIUS range and is engineered to provide reliable dry-running protection by monitoring active power. It operates within a current range of 10 to 115 A and supports voltage measurements up to 690 V. The device utilises a straight-through transformer and employs True RMS (TRMS) measuring procedures for both current and voltage, ensuring precise monitoring and protection.
This module is particularly suited for applications requiring compliance with ATEX and IECEx standards, making it ideal for use in potentially explosive atmospheres. It features robust electromagnetic compatibility, with emitted interference classified under IEC 60947-1 as class A, and offers immunity to various forms of conducted interference. The 3UF7122-1AA01-0 is designed for easy installation with screw and snap-on mounting options, and it maintains high performance across a wide range of environmental conditions, including temperatures from -25 to +60 °C and altitudes up to 4,000 metres.
With its compact dimensions of 94 mm in height, 55 mm in width, and 91 mm in depth, this module is a versatile choice for integration into existing systems. It provides essential protective functions such as overload protection, ground-fault monitoring, and power factor monitoring, ensuring the safe and efficient operation of your equipment.
