The Enerdoor FIN47SNB.050.2M.X.Y is a dV/dt filter snubber designed for motor protection applications. It features a 3-phase plus neutral star point configuration with excellent attenuation capabilities to reduce dV/dt.
This snubber operates at a nominal voltage of 600 Vac and has a rated current of unlimited. It can handle a maximum peak voltage phase to phase of 3000V and phase to ground of 3500V. The maximum power dissipation is 250W, with a fan dissipation of 20W. The device is rated for a frequency range of 50-1000 Hz and a carrier frequency (PWM) of 0-5 kHz.
Designed for easy installation, the FIN47SNB.050.2M.X.Y is suitable for applications with large motors, spindle motors, and long cable runs with variable frequency drives or servo drives. It protects motor windings, insulation, and bearings. The snubber has an IP20 protection rating and operates within a climatic class of -40 to +85° C. Its compact dimensions allow for parallel installation.
Key electrical characteristics include a very low power loss and availability with remote electronic control. The mechanical dimensions for Case 2 are 125mm width, 235mm depth, and 368mm height, with a weight of 10kg.
