3-Phase ac-filter power capacitors are ruggedized

September 9, 2020  Stephen Law

TDK CORP. EPCOS B32375 and B32376 series of power capacitors provide ac filtering in three-phase delta connection applications. B32375 series is for the low to medium power range and covers a capacitance spectrum from 3 x 5µF to 3 x 50µF with rated voltages from 250VRMS to 600VRMS. The can diameters are 50mm or 63.5mm and the heights vary between 128mm and 275mm depending on capacity and voltage. Devices have faston terminals for easy installation.

B32376 series is designed for high power with a capacitance range from 3 x 10µF to 3 x 400µF with rated voltages from 250VRMS to 1000VRMS. The can diameters are 116mm or 136mm and the heights are between 200mm and 275mm. Devices have screw terminal M10 for safety installation.

Devices are equipped with an improved safety device in accordance with IEC-61071, which eliminates the need for soldering. This results in a long service life of up to 100,000 hours at a continuous hot-spot operating temperature of 85°C and 200,000 hours at 70°C.
