It carries a 96-127 V AC/DC coil with spring-type terminals on the magnet coil, and the main power terminals accept stranded conductors from 16 to 70 mm². The contactor is rated for AC-3 switching at up to 1,000 operating cycles per hour, which covers the typical duty cycle for motor starting on conveyors, pumps, and fans. Mounting is via screw fixing to a vertical surface, with the contactor rotatable ±90° and tiltable ±22.5° front-to-back.
The 3RT1054-3NF36 is listed as a current-production item. No official successor has been declared for this order code. If a panel was specified around the 3RT1055-6QF35, note that the 3RT1054-3NF36 shares the same Size S6 frame and screw-fixing pattern, so mechanical fit in the same panel footprint is expected. Verify the coil voltage and auxiliary contact configuration against your BOM before committing.
The coil terminals are spring-type, accepting solid or stranded conductors from 0.25 to 2.5 mm², with a dual-conductor capacity of 2x (0.25 to 2.5 mm²). The auxiliary switch is present as a built-in feature. Its rated switching capacity at 24 V is 10 A, at 48 V and 60 V it is 2 A, at 110 V it is 1 A, at 125 V it is 0.9 A, and at 220 V it is 0.3 A.
Clearance and Timing
Arcing time is 10-15 ms. The contactor's mechanical life is typically 10,000,000 operating cycles.
