3TF SERIES :
With 3TF contactors Siemens has been offering a tried tested trusted solution to control, switch and protect your motors up to 450kW. 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.
The 3UA / 3UC thermal overload relays are suitable for customers from all industries, who want guaranteed optimum inverse time delayed protection of their electrical loads. The relays meet the requirements of IS/IEC 60947-4-1. They also offer protection against single phasing and unbalanced currents.These relays are widely used in electrical industry for reliable overload protection.
In the event of overload or a short-circuit, miniature circuit breakers (MCBs) safely cut the connected circuit and thus reliably protect electrical systems and devices against damage. Miniature circuit breakers (MCBs) in the SENTRON portfolio are also easy to assemble and install
