Applications & Use Cases

The ABB EF96-100 electronic overload relay is ideally suited for motor protection in heavy industrial applications where accurate trip thresholds and robust certification coverage are essential. Typical deployment scenarios include large pump stations, compressor drives, conveyor systems, HVAC plant rooms, and offshore or marine motor control panels where ATEX or LR/RINA ratings are mandatory. Its 36–100 A adjustment range makes it a versatile choice for motor starters built around ABB contactors in the EF96 series ecosystem, reducing the need for multiple relay variants across a site.
