The MTCR Rogowski coils combine precision with ease of integration:
- **Electrical:** The MTCR-24-300 Rogowski measuring coil measures a current range up to 300A.
- **Physical:** Rogowski coil length 97 mm, opening Ø 24 mm.
Mounting on conductor with provided cable tie.
Wire outputs length 2 m.
IP67 protection.
- **Accuracy:** Class 0.5% across the full scale.
- **Integration:** Thanks to their open core, the installation of current sensors is possible without disconnecting power cables.
Their flexibility allows easy installation in tight or hard-to-reach spaces.
- **Safety:** mV output thus no heating or risk of overcurrent.
- **MTCR-C Transducers:** The converters transform the mV coil signal into 0-1A or 0-5A, allowing the Rogowski coils to be used with a meter or a central unit with 1A or 5A input.
- **Centrals and meters for Rogowski coils:** Lettel offers measuring instruments with direct inputs for Rogowski coils:
– MCX4-34V: Three-phase meter for DIN rail mounting
– MAE-96V: Panel-mounted measuring centers.
- **The Rogowski coils can be connected:**
– Directly to modular electric meters MCX4-34V or to panel-mounted measuring centers MAE-96V
– To any meter or central with 1A input via the MTCR-C-x-1 converter
– To any meter or central with 5A input via the MTCR-C-x-5 converter
