The Fuji Electric 4NK0HH thermal overload relay is a motor-protection device designed to interrupt power when an overload is detected in a Fuji Electric TK-5-1N control circuit. It is rated for a current setting range of 0.95 to 1.45 A and carries the 4NK0HH part number, identifying it within Fuji Electric’s TK-5-1N family. Use this relay in motor protection applications requiring reliable thermal overload shutdown within the 0.95–1.45 A range to safeguard motor windings and equipment in electrical control systems.
