Contactors for railway applications
LTC Series

LTCS 250 Umax = 1500 V AC/DC Ith = 250 A L = 140 H = 156,5 P1 = 86	LTCS 250 2 POLI Umax = 1500 V AC/DC Ith = 250/500 L = 140 H = 156,5 P2 = 109	LTCS 250 3 POLI Umax = 1500 V AC/DC Ith = 250 A L = 140 H = 156,5 P3 = 154

LTC Series contactors are specially designed to be used on board of electric traction vehicles. The complete production process from design to final inspection is in accordance with ISO 9001 standards and the entire company is certified to this standard. This breaking circuit is equipped with permanent magnets to work efficiently both with high and low currents. DC control coil operates without economy resistor within a wide working range (at least ± 30%). A “varistor” cuts off the peak voltage when the coil is de-energized. Approximately 50.000 contactors LTC are working worldwide on the most important projects.
