Power contactors for AC and DC, Series CT
Owing to a new blowout technology, CT Series contactors can be used in almost any AC or DC railway network, even in countries where the normal tolerances are exceeded. The single pole contactor ensures low-wear and reliable switch­ing of both extremely low and very high loads.
Double and triple pole styles are being developed. Especially robust and environmentally friendly materials, from plastics featuring low smoke and low content of toxic gases up to cadmium-free contact tips, are used for the CT1000. It has been tested and approved by independent laboratories.
