Product details

The coil uses spring-type terminals, accepting 2x (0.5 to 2.5 mm²) solid or stranded. This eliminates the need for screw-torque checks on the coil circuit, speeding panel wiring.

Environmental and Mechanical Life

Typical mechanical life of the contactor is 10,000,000 operations. The arcing time is 10 ms at AC, and the switching frequency at AC-1 maximum is 1000 1/h.

Auxiliary contacts are rated for 10 A at 24 V, 2 A at 48 V, 2 A at 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, 5 hp at 230 V, 3 A at 400 V, and 0.6 A at 440 V. These cover typical control-circuit voltages across global panels.

Frequently asked questions

Where can I buy 3RT2027-2AL20-ZW97 and how do I get a price?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

What is 3RT2027-2AL20-ZW97's listed depth?

The depth is 97 mm.

What is 3RT2027-2AL20-ZW97's listed solid conductor range?

The main circuit accepts solid conductors from 1 to 10 mm².

Will 3RT2027-2AL20-ZW97 drop into a panel specified around 3RT2036-1AC20-ZX95 without rewiring?

Both are size S0 Siemens SIRIUS contactors with the same 45 mm width and 35 mm DIN-rail mounting, so the mechanical footprint is identical. However, verify coil voltage and terminal type — the 3RT2027-2AL20-ZW97 uses a 24 VDC coil with spring-type terminals, while the 3RT2036-1AC20-ZX95 may differ. Check the existing wiring and coil supply before substitution.
