Product details

It uses spring-type terminals for the magnet coil and is rated for a coil voltage of 95–130 V AC. The contactor mounts via screw or snap-on onto 35 mm DIN rail per DIN EN 60715, with a mounting position flexibility of ±180° rotation and ±22.5° tilt on a vertical surface.

The AC-3 maximum switching frequency of 750 1/h means this contactor is suited for standard motor starting duty — think conveyors, pumps, compressors — without overheating the coil or arc chamber. The AC-4 maximum of 250 1/h covers inching or plugging applications, so if your line does frequent reversing or jogging, stay within that lower cycle rate. The arcing time is a tight 10–10 ms, which keeps contact erosion predictable during fault clearing. The main contact wire range accepts solid or stranded conductors from 1 to 10 mm², and the auxiliary terminals accept 2x (0.5–2.5 mm²) — enough for standard control wiring.

The S0 frame size (width 45 mm, height 102 mm, depth 107 mm) fits standard 35 mm DIN rail enclosures. The coil holds at 95–130 V AC; dropout occurs below the initial value of 0.7 times rated voltage.

Frequently asked questions

Who supplies 3RT2027-2NF30 and how is it quoted for volume purchases?

The part is sourced through independent distribution and is quoted to order against an RFQ. Availability and current pricing are confirmed at quote time — no fixed price or stock count is published here.

What is 3RT2027-2NF30's listed depth?

The depth is 107 mm.

What wire sizes does 3RT2027-2NF30 accept?

Main contacts accept solid or stranded conductors from 1 to 10 mm²; auxiliary terminals accept 2x (0.5–2.5 mm²).

Will 3RT2027-2NF30 drop into a panel specified around 3RT2015-2AP02 without rewiring?

Both are SIRIUS S0-frame contactors on 35 mm DIN rail, so the footprint and mounting are identical. However, the 3RT2027-2NF30 uses spring-type terminals, while the 3RT2015-2AP02 may use screw terminals — check the termination style before assuming a drop-in swap.
