Applications & Use Cases

The ABB TA200DU-135 thermal overload relay is purpose-built for protecting three-phase AC motors in high-current industrial automation systems. Typical applications include compressor drives, pump stations, conveyor systems, HVAC equipment, and large fans where motor currents fall within the 100–135 A range. Its broad certification portfolio — covering UL, CSA, CE, UKCA, CCC, DNV, and LR — makes the TA200DU-135 suitable for global deployments across onshore industrial facilities, marine vessels, and offshore installations. Engineers and procurement professionals specify this relay when building motor control centres (MCCs), control panels, and motor starter assemblies requiring fully certified, DIN rail-compatible thermal protection.
