• 3RN2023 evaluation unit with ATEX approval and 2 sensor circuits for warning and disconnection
They comply with
• IEC 60947-8 Low-voltage switchgear and controlgear - Part 8:
"Control units for built-in thermal protection (PTC) for rotating
electrical machines"
• IEC 61000-6-2, IEC 61000-6-4. "Electromagnetic compatibility for industrial-process measurement and control equipment"
The 3RN2 thermistor motor protection relays with ATEX approval
fulfill SIL 1 in compliance with EN 50495.
The terminals of the auxiliary contacts are designated in
accordance with EN 60947-1.
3RN2 evaluation units are suitable for snap-on mounting on
TH 35 DIN rails according to IEC 60715 or for screw fixing using
an adapter (accessory).
Application: Thermistor motor protection devices are used for direct monitoring of the motor winding temperature. For this purpose, the motors are equipped with temperature-dependent resistors (PTC) that are directly installed in the motor winding and abruptly change their resistance at their temperature limit.
