Inter Thermistor Motor Protection Relay Price in Pakistan Rs 12,300/-. The Inter MKR-PTC (PTC-01) Thermistor Motor Protection Relay is a precision device engineered to safeguard electric motors against overheating by monitoring the resistance of PTC thermistors embedded in the motor windings. When the motor temperature exceeds a safe limit, the relay promptly disconnects the motor to prevent damage. Compact and DIN rail mountable, this relay is ideal for industrial applications where reliable thermal protection is critical for motor longevity and performance.
