This is a size S10 device in Siemens' 3RT contactor series, rated for heavy motor starting at 265 A continuous. The 3 Form A contact arrangement serves three-phase AC motor loads directly. Coil draw of 580 W reflects the inrush demands of AC-3 duty; operate time of 80 ms suits typical cascade or star-delta schemes.
Series 3RT1065 — Coil Voltage and Contact Variants
The 3RT1065 base covers at least eight coil voltages; the seed specifies 21–27.3 VAC/DC. Alternates in this dataset span:
- 3RT10652NP36 — 200–277 VAC/DC (US supply range)
- 3RT10652NF36 — 96–127 VAC/DC (mid-range Asian/Latin America)
- 3RT10652AR36 — 440–480 VAC/DC (UK/Middle East industrial)
- 3RT1065-2AB36 — 23–26 VAC/DC (extra-low voltage control circuits)
- 3RT10652XB460LA2 — 24 VDC only (solid-state coil design)
All share the same 265 A contact rating, chassis/DIN mounting, and box encapsulation. The S10 frame is consistent across the family, meaning mechanical mounting and power terminal layouts are identical.

| Similarity | — | 1.0 | 1.0 | 1.0 |
Readers must qualify these contactors against their specific control voltage and environmental requirements. Similarity values reflect parametric proximity in catalog terms, not performance equivalence.
Why similar — All four are 265 A, size S10, chassis/DIN mounted, box-encapsulated, and share the 3RT1065 base. The primary axis of variation is coil voltage suited to regional supply standards.
