⚠️ Nota: 3RT5 is economy version, mecánico & 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 kilovatios: fans, bombas de agua, compresores de aire, large belt conveyors, power distribution cabinets, climatización, production line main circuits.

📎 Remarks

Not vacuum contactor (vacuum type is 3RT12xx series)

Bobina universal CA/CC, 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 A / 132 kilovatios @ 400 V / Coil AC/DC 220~240 V / Incorporado 2NO+2NC / Busbar main connection

⚠️ Nota importante: Only equivalent in power rating. Dimensiones de montaje, agujeros de montaje, 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 A, 132 kilovatios @ 400 V, 3PAG

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

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

Obsolete old model: LC1F265M7 (AC220 V only, interrumpido, 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 A, 132 kilovatios @ 400 V, 3PAG

Bobina: 200–240 V AC/DC (sufijo 12 for this voltage range)

Contactos auxiliares incorporados: 2NO+2NC (-22), same as Siemens built-in 2NO+2NC

Circuito principal: Conexión de barras, same busbar terminal style as Siemens S10

Número de material: 1SFL547002R1222

Explicación del sufijo:

-22 = 2NO+2NC

-12 = 200–240 V AC/DC

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

Tabla comparativa

Recordatorios de selección

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.
