Selling Policy 25-000 - Distribution and Control Products and Services
Feature → Business Impact → Application: Modbus RTU or DNP3 RTU over Fiber Optic ST enables secure remote monitoring and data integrity. This fiber optic communication reduces EMI risk and supports long-distance links, improving uptime and visibility. Application in distributed motor protection across manufacturing, mining, and utilities is now more reliable. Feature → Business Impact → Application: 16 digital inputs and 9 digital outputs provide flexible control logic and protection schemes. The result is simplified wiring, reduced panel count, and faster commissioning. Ideal for machine protection, interlocking, and local control in assembly lines. Feature → Business Impact → Application: Wide voltage range (19–300 Vdc / 40–250 Vac) with 50/60 Hz compatibility supports global motors and mixed-drive environments. This enables worldwide installations and easier compliance with regional electrical standards. Application in multinational facilities and multi-region projects. Feature → Business Impact → Application: Zone Selective Interlocking and diverse sensing inputs (voltage, current, differential protection) enable selective tripping and precise fault localization. The business benefit is reduced outage impact and shortened repair windows. Use in feeder protection, substations, and critical plant power distribution. Feature → Business Impact → Application: Removable terminals and semi-flush mounting simplify installation, field replacement, and future upgrades. This minimizes downtime during maintenance and allows rapid retrofit into existing enclosures. Suitable for retrofit projects and modular panel builds. Feature → Business Impact → Application: EMR-4000 base relay compatibility and clear modular design support scalable protection architectures. For installers, this means straightforward upgrades and consistent protection logic across the Eaton E-Series family. Application in expanding control rooms and scalable protection networks.

FAQs
Plan for semi-flush mounting and removable terminals to simplify retrofits. Ensure voltage compatibility (19–300 Vdc / 40–250 Vac) and 50/60 Hz operation. Verify fiber optic communication links for Modbus RTU or DNP3 RTU and confirm I/O wiring to existing control panels to minimize downtime.
Key specs include 19–300 Vdc and 40–250 Vac operation, 50/60 Hz, 5 A and 1 A phase currents, 16 digital inputs, 9 digital outputs, and Modbus RTU or DNP3 RTU over Fiber Optic ST for field integration and remote monitoring.
Yes. It supports Zone Selective Interlocking (ZSI) with 1, enabling selective tripping and faster fault isolation in feeders and plant distribution networks, reducing outage impact and improving safety.
Compliances are listed as Manufacturer-verified. For your region and application, confirm CE, SIL, IP ratings, and any sector-specific approvals directly with Eaton prior to deployment to ensure regulatory alignment.
Removable terminals ease field maintenance and replacements, while compatibility with EMR-4000 enables scalable protection architectures. The combination of remote fiber communication, reduced wiring, and modular design supports reduced downtime and faster project ROI.
