Schneider Electric's LC1F330 model is a robust contactor designed for diverse electrical applications. It accommodates a system voltage that can reach up to 1000 V AC at frequencies of 50 or 60 Hz, as well as up to 460 V DC configurations. This contactor manages a rated operational current of 400 A when operated at temperatures lower than 40°C, and up to 330 A at 55°C, making it suitable for high-demand scenarios.
The unit consists of three poles, characterized as normally open (3P) configurations. This contactor maintains a rated impulse withstand voltage of 8 kV, offering strong protection against voltage spikes. Furthermore, it adheres to a rated breaking capacity of 2640 A, which is essential for safeguarding circuits during faults. The contactor’s rated insulation voltage extends to 1000 V as per IEC 60947-4-1 standards and 1500 V according to VDE 0110 group C, highlighting its suitability for various applications.
In terms of short-circuit protection, the LC1F330 is equipped to handle a rated short-time withstand current of 2650 A at 40°C for a duration of 10 seconds. Its associated fuse ratings indicate a 400 A aM rating for voltages up to 440 V, and a 500 A gG rating under the same voltage conditions. With an average impedance measured at 0.28 mOhm at 400 A, the efficiency of this design remains effective. The power dissipation per pole is rated at 44 watts under AC-1 conditions and 31 watts under AC-3 conditions.
This contactor also supports a wide range of control circuit voltage limits: from 24V to 1000V AC at frequencies of 40 to 400 Hz when used with LX1/LX9 coils, and from 24V to 460V DC when operated with LX4 coils. The operating times for the contactor are between 40 to 65 milliseconds for closing and 100 to 170 milliseconds for opening when utilized with the LX1/LX9 coil. Additionally, the LC1F330 is designed for plate mounting support, allowing for easy integration into various installations.
