Schneider Electric 3 Pole Contactors - LC1 Range Schneider Electrics LC1 contactors combine long mechanical and electrical life to offer a highly reliable contactor. The LC1 contactors offer quick and simple setup while maintaining compliance with international standards. Features and Benefits • Typically, applications include resistive loads and motor control
• Highly reliable
• Excellent quality
• Easily installed accessories
• Built-in coil suppression
• 3 NO poles
• 1 NO + 1 NC auxiliary contact composition
• Operating time when closing
• Contactors suffixed BL accept front mount auxiliary contact blocks but only the 2-contact version, they do not accept side mounted contacts What does the utilisation category AC1 and AC3 mean for the TeSys contactors? Contactor utilisation categories define the current making and breaking values, based on the type of load to be controlled and the operating cycle conditions.
AC-1: This applies to all AC devices with a power factor of at least 0.95. Example of use: resistive load, heating, distribution.
AC-3: This applies to squirrel cage motors where breaking occurs while the motor is running. Example of use: all squirrel cage motors, lifts, escalators, conveyors, bucket elevators, compressors, pumps, mixers, air conditioning units. What accessories are available? • Auxiliary contact blocks with serrated wiping action
• Front mount dust tight auxiliary contact blocks
• Pneumatic time delay blocks
• Transient voltage surge suppressors
• Interface modules and electronic timers
• Mechanical latching blocks
