Configured for thermal motor protection in motor control center applications, the Allen-Bradley 193-EEGE (193EEGE Electronic Overload Relay) provides direct physical execution of current monitoring and circuit interruption signals.

Model Matrix

• 193-EEGE: Base catalog number for the E1 Plus series electronic overload relay.

• Configuration: Integrated three-phase sensing with selectable trip class functionality.

Hardware Specifications

Industrial Control Integration

The 193-EEGE utilizes solid-state sensing to monitor current across three phases. Integration with industrial control networks relies on consistent I/O density scaling where the relay's auxiliary contacts (95-96 and 97-98) interface with PLC input cards. Firmware flash compatibility is governed by the E1 Plus internal logic architecture, ensuring that trip timing characteristics remain synchronized with the motor load profile. Deterministic fault reporting is achieved by wiring the N/C contact in series with the contactor coil, providing a fail-stop mechanism during phase loss or thermal overload events.

Ordering Information

• 193-EEGE E1 Plus Electronic Overload Relay unit.

• Documentation and hardware accessories are limited to the items explicitly listed; secondary mounting brackets for stand-alone DIN-rail application may be required based on physical configuration.

Field Installation Guidelines

• Contactor Mounting: The unit is engineered for direct attachment to Bulletin 100-C30 through 100-C85 contactors.

• Stand-alone Installation: When mounted independently of a contactor, use an approved terminal bracket for DIN-rail or panel surface installation.

• Auxiliary Wiring: Ensure terminal connections for 95-96 (N/C trip) and 97-98 (N/O alarm) use appropriate wire gauges to avoid mechanical stress on the relay body.

• Environmental Protection: Install within an enclosure meeting the required IP rating for the specific industrial environment to prevent ingress of conductive dust or moisture.

Frequently Asked Questions

• Can the trip class be modified in the field? Yes, the E1 Plus provides selectable trip class settings via the front-facing adjustment interface.

• How does the unit handle phase loss? It includes a 3-second phase-failure detection threshold to prevent motor overheating under unbalanced load conditions.

• Is the relay compatible with non-Allen-Bradley contactors? Yes, it can be configured for stand-alone mounting if terminal compatibility is managed via external busbars.

• What is the function of the N/O 97-98 contact? This contact is used to signal a fault condition to a remote monitoring system or PLC.

• Does this relay support hot-swapping? No, power must be disconnected from the motor branch circuit before removal or adjustment to ensure operator safety.

• Can the internal thermal model be reset remotely? Reset logic must be configured via the physical reset button or wired into a control loop based on local requirements.

• What is the minimum current rating for operation? The relay is designed for a minimum full load current (FLC) of 18 A.

• Are there specific torque requirements for terminals? Adhere strictly to the torque specifications provided in the product manual for power and control terminals to prevent loose connections.
