This device is CE compliant, SIL-rated for safety integrity, and offered with enclosure options that support IP-rated environments, helping you meet regulatory and harsh-site requirements. By aligning with Eaton’s protection ecosystem, it reduces installation time, simplifies spare parts management, and enables scalable automation across multiple lines. For procurement and operations teams, the predictable performance and certified reliability translate into reduced downtime, faster ROI, and a clearer path to compliant, high-availability control systems.
Product Information
The ES4T1R1RF3DB leverages a compact DIN-rail mounting design, enabling significantly denser panel layouts, easier wire routing, and faster field installation in modern control cabinets. This space efficiency reduces cabinet footprint, minimizes cabling complexity, and shortens commissioning times, delivering measurable labor savings for system integrators and OEM panel builders. Its architecture aligns with Eaton protection accessories, ensuring seamless compatibility with existing protective relays and circuit-control devices across diverse automation architectures. The device delivers rapid overcurrent and short-circuit protection with deterministic response, safeguarding drives, sensors, and critical loads from fault-induced damage and cascading failures. For engineering teams, this leads to fewer unwanted trips, improved fault diagnostics, and higher equipment availability on production lines such as packaging, conveyance, and processing cells. The combination of protection reliability and reduced downtime supports stronger safety programs and helps justify CapEx through lower maintenance and warranty exposure. Clear status indicators, standardized terminals, and tool-free assembly streamline commissioning, troubleshooting, and routine maintenance, even for technicians rotating through multiple production lines. The modular design simplifies replacement and spare-part management within Eaton’s protection ecosystem, reducing mean time to repair and inventory carrying costs. CE compliance and alignment with Eaton’s protection family provide a straightforward certification pathway and consistent performance across devices used in varied industrial environments. This consistency enables integrators to deploy scalable solutions with confidence, knowing wiring, communication, and protection parameters remain aligned as system complexity grows. Built for harsh factory floors, the ES4T1R1RF3DB withstands temperature variations, dust exposure, and electrical noise, contributing to longer service life in busy manufacturing facilities. Overall, it delivers lower total cost of ownership, safer operations, and faster ROI by simplifying installation, maintenance, and regulatory compliance in industrial automation projects.
