Mitsubishi TH-N120KP-67A Thermal Overload Relay

The Mitsubishi TH-N120KP-67A (TH-N120KP-67A) is a thermal overload relay designed for motor branch circuits to protect electric motors from sustained overload conditions and phase loss. Used in conjunction with Mitsubishi magnetic contactors across industrial motor control centers, machinery panels, and automated production systems, this protective device monitors line current and interrupts the control circuit when thermal thresholds are exceeded. The TH-N120KP-67A features bimetallic sensing mechanisms that trip the auxiliary contacts during overcurrent events, preventing thermal degradation or burnout of motor windings. Built for industrial environments, it supports dependable motor protection in pump systems, fans, conveyors, compressors, and material handling equipment. With a designated weight of 10 kg, the relay provides robust mechanical stability and reliable electrical isolation. Designed for seamless integration into factory automation architectures, the Mitsubishi TH-N120KP-67A ensures dependable operational safety, minimizes unplanned machine downtime, and serves as a direct replacement component for scheduled maintenance, control panel retrofits, and system overhauls.
