Applications & Use Cases

The ABB EF205-210 electronic overload relay is engineered for motor protection in heavy-duty industrial environments. Its broad 63–210 A setting range makes it suitable for large motors in manufacturing automation, pump stations, compressor drive panels, HVAC plant rooms, and process control installations. The ATEX and IECEx approvals extend its use to oil & gas, chemical, and mining facilities where explosive atmospheres may be present. Marine approvals (RINA, RMRS) qualify the EF205-210 for shipboard motor control centres and offshore installations.
