LTX line LTX contactors combine the typical robustness of Microelettrica Scientifica products with new and advanced concepts in electric arc breaking. They represent the right solution where high voltage rating, high thermal current and high breaking capacity are required. Specifically, they incorporate the traditional arc-chute design based on ceramic fins with an innovative blow-out system that enhances the contactor’s breaking capacity and guarantees the maximum breaking reliability over the entire range of currents. The opening mechanism enhances the LTX’s breaking and insulating perfomances, thanks to a fast opening speed and the highest distance between open contacts available on the market. This allows to achieve the highest performances and reliability demanded by the railway and industrial markets. Creepage and clearance distances designed to withstand voltages over 4 kV allow a safe use in polluted environments. The main power terminals are conceived to match all busbar and cable interfaces. This, combined with an extremely compact outline, reduces all efforts of integration and installation. The control circuit called “ECOBoost” has an energy saving function during the holding phase, to minimize energy consumption. It extends the control range to cover a wide variety of railway LV control ratings, without need of coil customization or external DC/DC converters, and is not sensitive to any voltage or temperature oscillation. Its LV interface has two separate channels, for power and control. The contactor’s feedback circuit is based on up to four IP67 auxiliary contact blocks, that are very resistant to pollution, dust and oxidation, and maximize the reliability of the feedback also under the lowest voltage and current conditions. LTX is available in 1-pole and 2-pole configurations, and is based on a modular concept that allows to combine several types of main body and arc-chute, to adapt it to the current and voltage performances required by the application. The LTX line is protected by International PATENT. Applications Railway substations Industry contactors Filter pre-charging Motors on-load disconnections Electromagnetic brakes control Heating/air conditioning systems Renewable energy
