🔁 Alternative Selection

Même cadre, different coil voltage: 3RT1065-6… change suffix for coil voltage

Economy equivalent: 3RT5065-6AP36 (Series 3RT5, dimension de montage identique, performances similaires)

⚠️ Remarque: 3RT5 is economy version, mécanique & electrical service life is shorter than premium 3RT1 series. Check datasheet before retrofit.

📋 Typical Applications

Starting/stopping of 3-phase asynchronous motors up to 132 kW: les fans, pompes à eau, compresseurs d'air, large belt conveyors, power distribution cabinets, CVC, production line main circuits.

📎 Remarks

Not vacuum contactor (vacuum type is 3RT12xx series)

Bobine universelle AC/DC, can be driven directly by PLC DC220 V or mains AC220 V

Main circuit is busbar type, cannot connect cable lugs directly; copper busbar adapter required

Benchmark target: Siemens 3RT1065-6AP36｜3P / AC-3 265 UN / 132 kW @ 400 V / Coil AC/DC 220~240 V / Built-in 2NO+2NC / Busbar main connection

⚠️ Remarque importante: Only equivalent in power rating. Cotes de montage, trous de montage, accessories and auxiliary contact base are NOT interchangeable. Verify cabinet space, wiring and auxiliary contact configuration before retrofit.

✅ Schneider (TeSys Giga, current production, replacement for old LC1F265)

LC1G265KUEN

AC-3: 265 UN, 132 kW @ 400 V, 3P.

Bobine: 100–250 V AC/DC wide voltage, covers 220–240 V perfectly

Standard: No built-in 2NO+2NC. Auxiliary contact block LA1G22 (2NON+2NC) must be added to match Siemens original configuration

Obsolete old model: LC1F265M7 (AC220 V only, abandonné, not recommended for new projects)

Full matched equivalent: LC1G265KUEN + LA1G22

✅ ABB AF series (AF with electronic wide-voltage coil, similar positioning to Siemens universal AC/DC coil)

AF265-30-22-12

AC-3: 265 UN, 132 kW @ 400 V, 3P.

Bobine: 200–240 V AC/DC (suffixe 12 for this voltage range)

Contacts auxiliaires intégrés: 2NON+2NC (-22), same as Siemens built-in 2NO+2NC

Circuit principal: Connexion par jeu de barres, same busbar terminal style as Siemens S10

Numéro de matériau.: 1SFL547002R1222

Explication du suffixe:

-22 = 2NO+2NC

-12 = 200–240 V AC/DC

-13 = 48–130 V AC/DC (do not select by mistake)

Tableau de comparaison

Selection Reminders

1. ABB AF uses electronic wide-voltage coil, different principle from Siemens traditional electromagnetic coil, surge suppression solution differs;
2. Schneider TeSys Giga overall size and mounting pitch differ from legacy LC1F and Siemens S10, cabinet space must be rechecked for retrofit;
3. For direct replacement of old LC1F265, OEM recommendation is LC1G265KUEN;
4. If you prefer built-in 2NO+2NC without extra auxiliary block, ABB AF265-30-22-12 is preferred.

Siemens SIRIUS 3RT10 Standard Power Contactors (3-pôle, AC-3, benchmark for 3RT1065-6AP36)

Note: 3RT10 = premium imported SIRIUS, bobine électromagnétique, contacteur moteur; Frames: S00 / S0 / S2 / S3 / S6 / S10 / S12; 400 V, 50/60 Hz; Only base catalog numbers listed; suffix varies by coil voltage, auxiliary contact and terminal type

Matching economy equivalent: 3RT50xx (local production, same mounting footprint, durée de vie plus courte)

3RT10 Base Catalog List (AC-3 @400 V)

Model Suffix Coding Rule (3RT10XX X P X X)

Take 3RT1065-6AP36 as example:

1. 1st segment (6): Cadre + main circuit terminal type (vis / jeu de barres)
2. UN: Code bobine

A = AC/DC 220–240 V (this item)

B = AC/DC 110–127 V

C = AC 24 V

D = AC 48 V

E = AC 110 V

F = AC 230 V

G = AC 400 V

M = DC 24 V

3. P.: Configuration des contacts auxiliaires

P = 2NO+2NC (intégré, this item)

K = 1NO+1NC

N = 0NO+0NC (pas de contacts auxiliaires intégrés, add 3RH1921)

4. Deux derniers chiffres: Type de borne

36: Main busbar, auxiliary screw terminals (common for S10/S12 high current)

30: Bornes à vis (S00~S6 small & medium frames)

Exemple: 3RT1065-6AP36 → Coil AC/DC 220~240 V, 2NON+2NC, busbar main connection

Other Series Branches (do not select incorrectly)

3RT12xx: Vacuum contactor (haute tension, frequent switching, not for standard motor duty)

3RT16xx: Railway dedicated contactor

3TC: Contacteur CC

3RT20xx: New generation SIRIUS (replaces legacy 3RT1, mixed local/import, similar dimension but accessories not interchangeable)

3RT50xx: Version économique, equivalent to 3RT10, moindre coût, shorter electrical life, preferred for retrofit

3RT60xx: Low-cost domestic small contactor (S00/S0)

Important Selection Notes

1. S00~S6 are mostly screw terminals; S10, S12 (225 A and above) are mainly busbar type, cable lugs cannot be crimped directly
2. 3RT10 is traditional electromagnetic coil; many new 3RT20 use electronic energy-saving coil, surge absorption scheme differs
3. Versions with built-in auxiliary contacts are limited; most stock types have no built-in aux contacts, external 3RH1921 is required
4. Old 3TF series is discontinued; prefer 3RT50 / 3RT20 for replacement
