Rogowski coil current sensor MTCR-150-3000

clampvoltage outputflexible

The MTCR Rogowski loops combine precision with ease of integration: - Electrical: The Rogowski MTCR-150-3000 measuring loop measures a current range up to 3000A. - Physical: Loop length 525 mm, opening Ø 150 mm. Mounting on busbar or cable using the supplied collar or mounting accessories. 2 m wire outputs. IP68 protection. - Accuracy: Class 0.5% over the entire range. - Integration: Thanks to their opening core, installation of the current sensors is possible without disconnecting power cables. Their flexibility allows easy installation in tight or hard-to-reach spaces. - Safety: mV output, so no heating or risk of overcurrent. - Accessories: MTCR-S3: Triaxial mounting support for fixing the Rogowski loop on a round conductor such as a cable. MTCR-CU: Mounting support for fixing the Rogowski loop on a busbar. MTCR-SV: Voltage pickup cord to be used with the MTCR-CU mounting support. - Associated Products: MTCR-C Transducers: The converters transform the mV loop signal into 0-1A or 0-5A, allowing the Rogowski loops to be used with a meter or a central unit with a 1A or 5A input. Central units and meters for Rogowski loops: Lettel offers measuring instruments with direct inputs for Rogowski loops: – MCX4-34V: three-phase meter for DIN rail mounting in an electrical cabinet – MAE-96V: measuring central units for panel or cabinet door mounting. The Rogowski CTs can be connected: – Directly to modular electric meters MCX4-34V or to panel-mounted measuring central units MAE-96V – To any meter or central unit with a 1A input using the converter MTCR-C-x-1 – To any meter or central unit with a 5A input using the converter MTCR-C-x-5 - Mounting accessories facilitate installation and ensure optimal accuracy class: – Mounting on cable: MTCR-S3 – On busbar or cable: MTCR-SV – With voltage pickup cord: MTCR-CU - Applicable Standards: EN61010-1:2010 +A1:2019, EN/IEC61010-2-032:2021 +A11:2021, EN/IEC61326-1:2021. - Compliance: CE, RoHS, REACh. - Technical characteristics / specifications: - Current range: up to 3000A - Loop length: 525 mm - Opening diameter: 150 mm - Output wires: 2 m - Protection: IP68 - Accuracy: Class 0.5% - Mounting: on busbar or cable (collar or accessories supplied) - Standards: EN61010-1:2010 +A1:2019, EN/IEC61010-2-032:2021 +A11:2021, EN/IEC61326-1:2021 - Compliance: CE, RoHS, REACh
