Product details

SIRIUS S3 Power Contactor — 3RT1446-6BB46-ZX95

The Siemens 3RT1446-6BB46-ZX95 is a SIRIUS S3 power contactor, rated for motor switching up to 38.2 kW at 690 V AC-3 and 29.9 kW at 500 V. The 24 VDC coil holds at 10 A, with pickup at 0.8x rated voltage and dropout at 1.1x.

Snap-on mounting onto 35 mm or 75 mm standard DIN rail, with screw fastening as an option. Side-by-side mounting permitted without derating for heat buildup. Dimensions: 152 mm depth, 90 mm width, 146 mm height.

Wire Termination and Temperature Derating

Main circuit screw terminals accept solid conductors: 2x (0.5–1.5 mm²), 2x (0.75–2.5 mm²), max 2x (0.75–4 mm²); AWG range 7–1/0. At 40 °C ambient, minimum permissible conductor size is 50 mm²; at 60 °C, 35 mm².

Frequently asked questions

What is the closest functional second-source for 3RT1446-6BB46-ZX95?

The 3RT1044-1FB46 is a smaller-frame SIRIUS contactor but shares the same 24 VDC coil voltage and screw-terminal design. However, the S3 frame (3RT1446) handles higher motor powers — up to 38.2 kW at 690 V versus the S2 frame's lower rating. A panel built for the S2 frame will need rewiring to accommodate the S3's larger footprint and higher current capacity.

What compliance documentation is available for 3RT1446-6BB46-ZX95?

The part carries RoHS substance prohibition compliance dated 05/01/2012. Rated insulation voltage is 1000 V, indicating IEC 60947-4-1 design. Standard Siemens SIRIUS documentation (declaration of conformity, CE, UKCA) applies; contact our team for specific cert copies with your RFQ.

Where can I buy 3RT1446-6BB46-ZX95 and how is it quoted?

This part is sourced through independent industrial distribution. Submit an RFQ for your target quantity; we confirm availability and current pricing at quote time. No minimum order quantity restrictions — single units or volume lots, same process.
