Series Eaton - ETR4

Eaton - ETR4

The Eaton ETR4 series is a complete line of electronic control relays built for everyday electrical work. Designed for installers who need dependable timing and switching without complicated setup, this series covers everything from basic time delays to advanced multi-function control. Whether you are wiring lighting circuits, motor controls, or building automation panels, the ETR4 series gives you the flexibility to match the exact job requirements. Each unit is compact, clearly labeled, and ready to drop into standard DIN-rail enclosures.

Reliable Timing and Control Solutions

Timing accuracy matters when your circuits need to run on a strict schedule. The ETR4 series includes models like the ETR4-51-A and ETR4-11-A, which offer precise short-delay and delayed-on functions. These relays use stable electronic components to keep consistent performance across temperature changes and power fluctuations. Installers can trust them to trigger pumps, fans, or lighting systems exactly when needed, reducing false trips and keeping systems running smoothly.

Flexible Multi-Function Options

Not every project fits a single function, and the ETR4 series knows that. Models such as the ETR4-69-A and ETR4-70-A provide multi-function control in a single compact housing. The ETR4-70-A even supports potentiometer adjustment for fine-tuning settings on site. This means you can handle complex sequencing, cycle control, or backup switching without stocking multiple relay types. One series, one supplier, and fewer parts to manage on the job site.

Easy Installation and Wiring

Time is money on every electrical job, and the ETR4 series is built to save both. Clear terminal markings, straightforward wiring diagrams, and standard DIN-rail mounting make setup fast and error-free. The compact footprint leaves plenty of room in control panels, while the robust plastic housing protects against dust and minor impacts. Installers spend less time troubleshooting connections and more time finishing the job to spec.

Built for Real-World Electrical Work

Control relays face heat, vibration, and constant switching, so durability is non-negotiable. The ETR4 series is engineered to handle demanding commercial and industrial environments without compromising performance. With solid construction, reliable contact ratings, and straightforward maintenance, these relays keep your systems running year after year. When you choose the Eaton ETR4 series, you are choosing control equipment that works as hard as you do.
