jb Motor Capacitor - CBB61

Since jb launch of the motor capacitors, many customers liked it very much. Now, we list more comprehensive information about the motor capacitors for you reference.

General description:
Broadly applied to starting and running of single-phase AC motors at 50Hz(60Hz) frequency for air conditioners fans, electric fans and exhaust fans, ect; at compatatively low reted power.

The capacitor takes heavy-edge metallized. AI/Zn PP film or web-like fuse metallized PP film as dielectrie, its components are assembled in flame-retardant ABS or PBT square crust, impregnated with flame-retatdant epoxy resin. It has high reliablity and stability.

jb Has Great Support for CBB61 Motor Capacitors -- JFS-6

Motor capacitors are operation capacitors for single-phase induction motors with auxiliary winding and three-phase motor in steinmetz circuits.

Motor capacitors are self-healing capacitors, i.e. a weak point in the dielectric would become ineffective by itself since the metal coating evaporates at the weak point.

We jb produce 18 types of Motor Start Film Capacitors, with high quaity, we also offer competitive prices and short lead time, we welcome your inquiries to info@jbcapacitors.com

Below are some main applications for motor start capacitors. and our JFS-6 series motor start capacitor picture.
Household and domestic appliances.
Office machines.
Heating and ventilation techniques.
Garden and recreational equipment.
