Overview
The CHINT NR2-25 Thermal Overload Protection Relay is a precision-engineered safety device designed to protect electric motors and circuits in the E-TUN-4525 Heat Tunnel from overloads and phase failure conditions. By automatically interrupting the control circuit during abnormal current flow, it safeguards heating fans, conveyor drives, and auxiliary equipment from thermal damage and mechanical failure.
Key Features
-
Adjustable Current Range: Supports a wide trip current adjustment, allowing precise protection tuning based on the motor's full load current.
-
Phase Loss Sensitivity: Detects single-phase failures in three-phase circuits, preventing motor burnouts.
-
Manual or Automatic Reset: Equipped with a front-mounted STOP/RESET button and adjustable reset modes for operational flexibility.
-
Integrated Test Function: Test button allows for safe functional verification without removing the relay from service.
-
Compact Mounting: Designed to directly mount on CHINT contactors, such as the NC1 or other compatible models, simplifying installation.
