Insert-Terminal CBB61 Square Capacitors from Our Cixi Factory

Cixi Riyi Capacitor Factory produces AC motor capacitors and lighting compensation capacitors in Cixi, Zhejiang, China, on the south bank of Hangzhou Bay Bridge. Our AC Cbb61 Insert Type Square Capacitor Suppliers range is the terminal-connection branch of the CBB61 square motor capacitor line: rectangular metallized film capacitors whose connections are made with insert lugs on the motor terminal block rather than with wire leads.

Three standard ratings sit in this group — 2µF, 4µF and 7.5µF, all at 450V — across S0 and S3 safety classes. Custom capacitance, terminal pitch, case height and lead-free terminal geometry are developed from your drawing or sample, and the same body platform feeds our AC Cbb61 Wire Lead Motor Capacitor Suppliers line when a leaded version suits the assembly better.

2 / 4 / 7.5 µF Listed insert models, all rated 450V AC
1+1 & 2+2 Insert terminal groups in the current range
25,000 m² Plant and production workshop area
60,000 pcs/day Daily output on 11 slitting and 15 winding lines

Model Capacitance Rated voltage Terminal group Safety class Typical fit
CBB61 2µF 450V S3 2 µF 450V AC 2+2 insert lugs S3 Fan and blower motors with a fast-on terminal block
CBB61 4µF 450V S0 4 µF 450V AC 1+1 insert lugs S0 Compact single-phase drives and light-duty circulation fans
CBB61 7.5µF 450V S0 7.5 µF 450V AC 1+1 insert lugs S0 Range hoods, water pumps and general motor starting duty

Capacitance Coverage at 450V

Bar length shows the nominal capacitance of each listed insert model. Voltage is common at 450V AC; the platform changes only in capacitance value and terminal layout.

Safety Classes S0 and S3 in Practice

S0 and S3 describe the internal construction and failure behaviour of the capacitor, not its capacitance. A 2µF 450V S3 part and a 4µF 450V S0 part can sit in the same appliance family; the class follows the risk the motor circuit presents if the film fails.

  • S3 construction
    Used where the failure mode must be contained and the circuit must stay safe without external protection. Our 2µF 450V model in this group carries the S3 class.
  • S0 construction
    Applied to standard single-phase fan and pump motors where the appliance already provides the required protection. The 4µF and 7.5µF models are supplied in S0.

Because the body is a metallized film element, self-healing behaviour during transient overvoltage is intrinsic to the technology. We confirm the class that matches your motor circuit and the certificate marks your market requires before the winding and case dimensions are fixed.

Where Insert-Type Square Capacitors Fit

Ventilation and fan motors Square bodies mount flat against the motor bracket, and insert terminals push straight onto the motor plug without an extra lead harness.
Range hoods and household appliances Washing machines, dryers, range hoods and small circulation fans use these ratings for phase shift in the auxiliary winding.
Pumps and compressor motors Larger values from the same capacitor family serve water pumps and single-phase compressors where the terminal block is inside the enclosure.

The insert style is chosen at the assembly line, not on the test bench: it removes one soldered or crimped lead joint, shortens the harness and keeps the capacitor seated on the terminal rail. For projects needing explosion-proof S3 models with wire leads, the CBB61 lead group runs on the same winding equipment.

Production, Inspection and Acceptance

Eleven automatic slitting machines and fifteen imported winding machines run the film and winding stages, with a daily output of 60,000 pieces. More than 150 employees, including 21 technical staff and 3 engineers, cover process control and customer-specific development.

  • Capacitance and dissipation factor verified on production lots
  • Insulation resistance and dielectric withstand between terminals and case
  • Insert lug geometry, pitch and insertion fit checked against the sample
  • Case dimensions, marking and print inspected before packing
System and product certification

Our quality system is certified to ISO9001 and our environmental system to ISO14001. Product certificates held across the range include CQC, TUV, VDE, IMQ, UL and CE.

Acceptance criteria, sample quantities and the drawing revision used for approval are agreed before mass production, so incoming inspection at your plant matches the approved sample.

Information We Use to Configure Your Capacitor

Parameter What we need from you Why it decides the build
Capacitance and tolerance Nominal µF and acceptable tolerance band Sets the phase shift and available motor torque
Voltage and frequency Working V AC and 50 Hz or 60 Hz supply Determines film thickness and dielectric margin
Safety class S0 or S3, plus any required mark Governs internal construction and failure containment
Terminal group 1+1, 2+2 or a custom pitch and lug size Must match the appliance terminal block
Case and mounting Height, width and fixing position Fits the motor housing or mounting bracket
Ambient and duty Operating temperature and continuous or intermittent running Influences life expectation and material grade
Marking, packing, delivery Print data, carton count, annual volume and destination port Sets running order planning and shipping terms

Send a drawing, a sample or the motor nameplate data and we return a proposal with the exact capacitance, terminal group, case dimension and certificate mark for your market. Custom development from customer drawings or samples is part of our normal order flow.

Frequently Asked Questions

How does the insert type differ from the wire lead type?

Insert models connect through terminal lugs pressed onto the motor block; lead models carry factory-fitted wires. Both use the same square CBB61 film body, so the choice depends on how your motor is terminated — see the AC Cbb61 Square Motor Fan Capacitor Manufacturer range for the full comparison.

Which values are available in the insert group?

The listed models are 2µF, 4µF and 7.5µF at 450V, with 2+2 and 1+1 terminal groups. Other capacitance values can be produced on the same platform from your sample or drawing.

Can you build a custom terminal spacing or case height?

Yes. Terminal pitch, lug size, case dimension and marking are all defined at tooling and winding stage, so a custom version is quoted from your drawing or sample before the first production run.

Should I specify S0 or S3?

That follows the protection already present in your motor circuit and the safety mark your market requires. Tell us the appliance type and the certificate mark, and we match the class to the application.

Which related capacitors do you supply?

Alongside CBB61 we produce CBB65 explosion-proof run and dual-run capacitors, CBB60 AC motor run and start capacitors and CBB80 lamp power factor compensation capacitors, covering household appliance, pump, fan and lighting applications.

How are orders packed and shipped?

Cartons and inner packing are agreed with the order, and shipments leave through Ningbo by sea, with air freight available through Ningbo and Shanghai airports when timing requires it. Payment terms are confirmed at quotation stage.
