What does a Trombetta do?
Trombetta performs a wide range of final assembly services including potting, conformal coating, over-molding, box build, and other value added services to meet the specific needs of each application.
What are DC contactors?
A DC contactor is an electrically controlled device designed to switch current on and off. DC contactors control current in DC circuits by closing and opening internal contacts. DC contactors control much lower voltages than AC circuits and offer the benefit of minimal arcing as the circuit opens and closes.
Can I use AC contactor for DC?
So AC contactors and DC contactors cannot be replaceable to each other. If we put the AC contactor in the DC circuit, it will burn out because of the excessive current. Because there is inductive reactance in alternating current but not in direct current.
Is Trombetta Italian?
Trombetta Name Meaning Italian (especially eastern Sicily): metonymic occupational name for a trumpeter or bugler, from trombetta ‘bugle’, a diminutive of tromba ‘trumpet’.
How does a Trombetta solenoid work?
Trombetta solenoids turn electric power into mechanical work. By generating a linear electrical magnetic field that interacts with mechanical components, solenoids help close and open internal valves, and initiate mechanical chain reactions to monitor other operational circuits.
Why is a DC contactor bigger than an AC contactor?
The number of coils of the DC contactor is greater than the number of coils of the AC contactor. If the primary loop current is too large (ie> 250A), the contactor should use two-phase winding coils in series. The coil reactance of the DC relay is huge, but the power consumption of the current is less, or even smaller.
What is the difference between DC contactor and AC contactor?
The AC contactor contains a grid arc extinguishing device as opposed to the DC contactor, which has a magnetic arc extinguishing device. The AC contactor uses the principles of alternate current to operate and is equipped with an iron core that leads to eddy current loss and hysteresis loss.
Where does the name Trombetta come from?
Can we use AC contactor for DC?
Yes – as long as the rating of the A C contactor is a minimum of 5 x (preferably 6 x) of the D C contactor rating. This is mainly because of the steady state nature of the D C voltage and therefore its current. D C is generally used at lower voltage levels, common use and at very high levels for transmission purposes.
