The Phoenix Contact ELR 1-24DC/600AC-20 is a compact electronic 1-phase contactor for reliable switching of AC loads in industrial control panels. With a 24 V DC control concept and zero-cross switching, it delivers wear-free, low-EMI performance for resistive and moderate inductive applications in machine building, HVAC, and process automation.

The device accepts a 4–32 V DC control input, making it PLC-friendly, and switches 42–660 V AC on the load side with 20 A at AC-51 and 5 A at AC-53a. Zero-cross turn-on limits transients, while an RCV protection network and a green status LED enhance operational safety. It handles inrush currents up to 250 A for 10 ms, supports switching frequencies up to 25 Hz, and offers robust screw terminals (M4) for 0.5–4 mm² conductors. The 22.5 mm-wide DIN-rail housing operates from -30 to 70 °C and complies with EN 61000-4-2.

Engineered for space-saving panel layouts and maintenance-free solid-state switching, this electronic contactor helps OEMs and MRO teams standardize on dependable Phoenix Contact technology, and it comes with a 1-year warranty to support long-term project reliability.
