Electrolytic capacitors
MS/MD Motor Starting Capacitors are aluminum electrolytic capacitors for AC operation, aiding motor start by providing leading current. Designed for intermittent use, they meet VDE 560-8, BS 5267, and IEC 252 standards, with MS offering single and MD dual voltage ratings.
MS / MD Motor Starting Capacitors
A range of aluminium electrolytic capacitors specifically designs for a.c. operation which help to start the motor by providing a leading current to the auxillary winding. The capacitor is not permanently connected to the winding of the motor and is switched off after starting, usually automatically. Capacitors for this application are designed for intermittent duty only, and must be capable of withstanding the a.c. voltage applied to the motor during starting. This range of capacitors is housed in a moulded case and carry approvals to VDE 560-8 and comply with the requirements of BS 5267 and IEC 252. The MS series is rated at a single voltage whereas the MD has a dual voltage rating.
