Product details

It measures 55 mm wide by 130 mm deep by 114 mm tall, so it occupies a standard three-module footprint on the rail — no surprises for panel layout.

The coil is rated 83…155 V (likely AC/DC, though the evidence doesn't specify). Inrush current peaks at 1.5 A, and the holding power draw is 2 VA at both 50 and 60 Hz — that's a light load on the control transformer, so you can share a 24 VDC or 110 VAC supply with other devices without worrying about voltage sag on pickup. Mechanical life is typical at 10 million operations. Electrical switching rates vary by duty: up to 1,200 ops/h for AC-1 resistive loads, 1,000 ops/h for AC-3 motor starting, and 300 ops/h for AC-4 plugging/inching.

That's tight enough for dense DIN-rail packing — just keep the 6 mm side gap for arc venting. Spring-type terminals accept 2x (0.5…2.5 mm²) solid or stranded wire. No screw torque to check — just strip and push.

Frequently asked questions

What are the key dimensions of 3RT2035-3NF30?
