jb A.C motor-start capacitors are electrochemical devices consisting of compactly wound aluminum foil separated by layers of paper, which are impregnated with a conducting electrolyte. Etching of the foil prior to formation and winding increases both the effective foil surface area and the capacitance per unit volume of the finished capacitor. The entire assembly is housed in a case of moisture and oil resistant molded plastic. These capacitors are rated for operation in ambient temperatures from -40°C to +65°C and at a frequency of 50Hz to 60Hz.

These capacitors are designed for motor starting and other intermittent duty AC applications. They are non-polarized and are normally designed with dual quick terminals. These terminals allow for the easy attachment of a bleeder resistor(usually 15K ohm at 2 watt). This saves relay switch contacts and capacitor, particularly in capacitor start-run applications. The quick connect terminals also eliminate the need for soldering.

A motor capacitor, such as a start capacitor or run capacitor, including a dual run capacitor, is an electrical capacitor that alters the current to one or more windings of a single phase AC induction motor to create a rotating magnetic field. It is used in air conditioners, hot tub/jacuzzi spa pumps, or forced air heat furnaces for example. A round dual run capacitor is used in some air conditioner compressor units, to boost both the fan and compressor motors.

CBB60 Capacitor takes heavy-edge metallized Al/Zn PP film or web-like fuse film as dielectric. Its components are sealed with flame-retardant epoxy resin. It has cylindric outline with high reliability and stability. CBB60 capacitor has features of small size, light weight, small tangent in waste angle, and good self-concrescence. Applicable to startand operation with 50/60Hz. A. C single motor, specially suit for micro pump, baric pump, micro motor and so on.

1) Very small dissipation factor, small inheterent temperature rise.
2) High insulation resistance.
3) Good capacitance stability.
4) Excellent self-healigh property.
5) Safety and hight reliability due to flame reatardant plastic or metal case enclosure, flame retardant opoxy resin endfill.
6) It is applicable for the starting and running of AC single-way motor with 50~60Hz frequency.
7) Special requirment can be made at the request of customers.

According to the provisions of China’s national standard GB2470-81, the capacitor named product 
model generally consists of the following four parts:

Part I: The letter represents the name, the meaning of C is a capacitor.
Part II: with letters material.
Part III: numerical classification.
Part IV: The digital serial number.

For example: “CBB60” Capacitor
C – meaning Capacitor
B – meaning the Dielectric is a non-polar organic film
B – meaning the Dielectric material is polypropylene
60 – meaning Plastic can motor run capacitor Broadly applied to starting and running of  AC single-
phase motors at 50/60Hz frequency for AC motor, electric engine, water pump, generator and high 
efficiency compressors of refrigerators etc.
