PKE16-TB-10 — Eaton PKE Smart Motor-Protective Circuit Breaker
The Eaton PKE Smart Motor-Protective Circuit Breaker is an intelligent electronic motor protection and switching device covering motor currents from 0.1 A to 32 A, combining the functions of a motor circuit breaker, electronic overload relay, and IO-Link communication interface in a single compact 45 mm wide DIN-rail device. The PKE16-TB-10 is rated for motors up to 16 A (7.5 kW at 400 V) and replaces the traditional combination of a PKZM motor-protective circuit breaker and a ZB overload relay with a single device that provides tighter protection accuracy, remote trip reset capability via IO-Link, and real-time current monitoring without additional measurement equipment.
The PKE's electronic trip unit continuously monitors true RMS motor current and calculates the thermal motor model in real time, providing thermally accurate overload protection that responds to actual motor temperature state rather than simply tripping at a fixed time-current threshold. This approach eliminates nuisance tripping during legitimate temporary overloads (such as frequent starts of high-inertia centrifugal pump sets) while ensuring reliable tripping during genuine sustained overloads — a balance that conventional bimetallic overload relays cannot achieve with acceptable consistency. The IO-Link communication interface transmits real-time current values, thermal model status, trip history, and motor protection diagnostics to an IO-Link master connected to the plant PLC or SCADA system, enabling predictive maintenance based on actual motor loading data rather than fixed maintenance schedules.
The remote reset capability is a significant operational advantage in Saudi Arabia's large process plants and water station networks: a PKE trip can be remotely reset from the control room via IO-Link after the technician has confirmed the fault is cleared, eliminating the need to send maintenance personnel to individual motor control centres distributed across large sites. In ARAMCO and SABIC facilities where MCCs may be located in remote process areas, the ability to reset tripped starters from the DCS operator station reduces maintenance response time from hours to minutes and reduces exposure of personnel to energised switchgear.
The PKE connects mechanically with Eaton's DILM contactors via direct coupling without wiring, creating a complete motor starter combination that is IEC 60947-4-1 coordinated. The combination is available in Type 1 (damage permitted) and Type 2 (no damage) short-circuit coordination classes, with Type 2 coordination documentation provided for ARAMCO and SABIC applications that require it by their corporate electrical standards. Razz Middle East stocks PKE in all standard current settings and provides engineering support for starter combination selection.

Key Features & Benefits
- Electronic true-RMS thermal model replaces bimetallic overload relays with a motor temperature simulation that eliminates nuisance trips on legitimate temporary overloads while ensuring reliable tripping on genuine sustained faults.
- IO-Link communication transmits real-time motor current, thermal model state, trip history, and diagnostics to the plant PLC or SCADA, enabling predictive maintenance based on actual motor loading trends.
- Remote trip reset via IO-Link allows control room operators to reset tripped starters after fault confirmation without dispatching maintenance personnel to remote MCC locations in process plants.
- Direct mechanical coupling with Eaton DILM contactors creates a compact, wiring-free motor starter combination with IEC 60947-4-1 Type 2 short-circuit coordination documentation for ARAMCO and SABIC applications.
- Single device replaces the PKZM motor-protective circuit breaker plus ZB overload relay combination, reducing DIN-rail space by 30% and eliminating the potential for miscoordinated settings between separate devices.
- Phase loss, phase imbalance, and motor thermistor (PTC) protection functions are integrated alongside the thermal model, providing a complete protection package without additional relay modules.
Industrial Applications in Saudi Arabia
- ARAMCO process plant MCC motor starters in the Eastern Province, where IO-Link remote reset reduces maintenance response time from hours to minutes for distributed starter panels in remote process areas.
- SABIC petrochemical facility utility motor control where real-time IO-Link current data feeds DCS predictive maintenance systems, enabling condition-based motor maintenance rather than time-based schedules.
- NWC and SWCC pump station motor starters where thermal model overload protection eliminates nuisance tripping during frequent starting cycles on large centrifugal pump sets.
- NEOM smart industrial facility MCC panels where IO-Link integration is part of the digital infrastructure specification, providing motor-level data to the facility-wide IoT and CMMS platform.
- Building services motor starters for HVAC fans and pumps in commercial and government buildings, where the PKE's compact size and direct contactor coupling simplifies panel design and reduces assembly cost.
- Water treatment plant motor control at NWC facilities, where phase loss detection protects motor windings during partial supply faults on remote rural pump station power supplies.
