MDB 400/13 Block United Kingdom Sales
The BLOCK MDB 400/13 is a three-phase motor reactor designed to protect motors in variable frequency drive systems. It offers high damping of edge steepness and inverter switching frequency, reducing leakage currents and allowing for long shielded cable lengths. With an inductance of 3 × 0.42 mH and a rated current of 3 × 13 A AC, it supports motor or converter power up to 4 kW. The reactor features high efficiency, excellent corrosion protection, and low noise operation due to vacuum impregnation.
