Description
The NR2-25G/9-13 thermal overload relay is a protective device used in electrical systems to safeguard motors against overcurrent and phase failure. It operates by monitoring the current flowing through the motor and disconnecting the circuit if the current exceeds a safe limit, preventing potential damage or overheating. This specific relay model is part of the NR2 series and complies with international standards like IEC/EN 60947-4-1, ensuring reliability and wide applicability in industrial and commercial settings.
