Mitsubishi TH-T18KPCX-9A Thermal Overload Relay

The Mitsubishi TH-T18KPCX-9A (TH-T18KPCX-9A) is a thermal overload relay designed for reliable motor overload and phase-loss protection in low-voltage industrial control and motor starter assemblies. Part of the Mitsubishi thermal overload relay range, this protective device pairs directly with compatible magnetic contactors to monitor continuous motor operating current and prevent thermal damage from prolonged overcurrent or locked-rotor conditions. Featuring a 9 A nominal rating, the bimetallic tripping mechanism responds accurately to excess heat, triggering the auxiliary trip contact to de-energize the contactor coil and safeguard connected equipment. It supports standard manual or automatic reset operations, integrated trip indication, and screw terminal connections for straightforward power and control circuit wiring. The unit weighs 10 kg as configured and is typically utilized across factory automation environments, pump panels, conveyor drives, compressor systems, and material handling switchboards where dependable motor control and thermal protection are essential. It serves as an exact replacement component during routine maintenance or electrical cabinet upgrades.
