Benets

• Intermittent AC motor starting

• 6.3 mm double amp tags (quick connect types)

• VDE approved to IEC 60252–2

Overview

KEMET's MS/MD Series of aluminum electrolytic

capacitors are designed for intermittent duty only and

capable of withstanding the AC voltage applied to the

motor during starting. The capacitor construction is

comprised of either double anode or O-style (double anode

and oating cathode) windings, which are housed in a

molded plastic case. KEMET's MD Series is VDE approved

to IEC 60252-2 for the dened ratings.

Applications

KEMET's MS/MD Series is a range of aluminium electrolytic

capacitors specically designed for AC operation which

helps to start the motor by providing a leading current to

the auxiliary winding. The capacitor is not permanently

connected to the winding of the motor and is usually

switched off automatically after starting.

AC Motor Start Aluminum Electrolytic Capacitors – MS/MD Series, +60ºC/+70°C Discharge Resistors A discharge resistor may be fitted to a motor start capacitor to prevent electrical overstress of the capacitor and/or for safety reasons. In accordance with IEC 60252, the resistor value should be such that it reduces the voltage on the capacitor, from the line voltage to less than 50 V within 60 seconds.
