Product details

The Siemens SIRIUS 3RT1346-1AB00 is a size S3 power contactor rated for motor switching up to 53 kW at 230 V, 50 Hz. Pollution degree 3 means it handles the conductive dust and humidity you get in a real motor control center, not a clean room.

Main current circuit uses screw-type terminals accepting solid wire from 2x (0.5... 1.5 mm²) up to max 2x (0.75... 4 mm²), and stranded from 2x (10... 50 mm²). For AWG, main contacts accept 2x (10... 1/0).

Protection and coordination

The contactor's mechanical life is typical 10,000,000 operations, and it's rated for 1,000 cycles per hour at AC-1 maximum. Arcing time runs 10 to 15 ms. These numbers matter for coordination studies and for estimating contactor wear in high-cycle applications like conveyor or pump cycling.

Frequently asked questions

What is the depth of 3RT1346-1AB00?

The depth is 139 mm, width 93 mm, height 146 mm. It's a size S3 contactor that snaps onto 35 mm or 75 mm DIN rail.

What wire sizes does 3RT1346-1AB00 accept?

Solid wire: 2x (0.5... 1.5 mm²), 2x (0.75... 2.5 mm²), max 2x (0.75... 4 mm²). Stranded: 2x (10... 50 mm²). AWG main contacts: 2x (10... 1/0). All via screw-type terminals.

Will 3RT1346-1AB00 drop into a panel specified around 3RT1044-1FB46?

Both are SIRIUS power contactors, but they are different sizes and ratings. The 3RT1346-1AB00 is an S3 frame; the 3RT1044-1FB46 is a different frame size. Physical dimensions, terminal spacing, and current ratings differ — panel fit is not guaranteed without verifying mounting and wiring clearances.
