For more than 110 years, Siemens has been developing and manufacturing industrial control products.
We offer a wide product range which fulfills the demands of our customers regarding performance and
reliability. Our aim is to make industrial operation easier ensuring flexible mounting, modular
construction and high functionality. With 3TF contactors Siemens has been offering a tried tested
trusted solution to control, switch and protect your motors upto 250kW.
Applications
3TF power contactors are suitable for switching and controlling
squirrel cage and slip-ring motors as well as other AC loads, such
as solenoids, capacitors, lighting loads, heating loads and
transformer loads.
Standards
Contactors conform to IS/IEC 60947-4-1. They also carry the CE
mark.
Coordinated feeder
Contactors and bi-relays have been tested for type-2 coordination
at Iq = 50kA, 415V AC, 50Hz as per IS/IEC 60947-4-1, for both fuse
protected as well as fuseless motor feeders.
Range
Air break contactors are available from 9 A to 475A in 3 pole
version.
Also available in 2 pole AC version from 45A to 400A.
