ELECTRICAL SAFETY SOLUTIONS / CONTACTOR RANGE Type SEC RAIL VEHICLES / FIXED INSTALLATION

GENERAL INFORMATION The SEC contactor is a high duty class component, ~ designed to withstand the most severe applications in terms of environment and required performances ~ for rail mobility or fixed installations. Combining high electrical and mechanical endurances, efficient low current bi-directional blow-out device, and a smart 3 M control unit making the SEC operation independent 3~ from both ambient temperature and control voltage, the SEC is a 3 unique contactor to be used almost regardless of theM service conditions. 3~ APPLICATIONS, TYPICAL EXAMPLES DC rail vehicle Power line Current...

MAIN MAIN BENEFITS BENEFITS Operational frequency category C3 for 1,000 A and C2 for 1,300 A with a minimum mechanical durability of 2,000,000 operations Efficient blow-out circuit for low current interruptions Reduced power consumption thanks to a coil controller that controls the closing and opening operations Closing and opening performances independant from both control voltage level and ambient temperature Horizontal or vertical mounting Double pair of main contacts allowing a longer life time Low maintenance requirements and easy access to the main contacts for replacement. All arc chutes...
