CBB60 12uF/4.2uF 450V S0, Dual Run Capacitor for Main and Auxiliary Motor Windings

CBB60 12uF/4.2uF 450V S0, Dual Run Capacitor for Main and Auxiliary Motor Windings: an aluminum-case dual run capacitor that puts a 12uF and a 4.2uF section behind one set of insert terminals, so a single part can serve two motor circuits.

Key Features:
• A 12uF main section and a 4.2uF auxiliary section share one set of insert terminals, so one part serves two circuits.
• The 450V rating leaves comfortable margin on common single-phase supplies.
• A self-repairing metallized layer keeps the capacitor working after occasional overvoltage events.
• Minimal self-heating during long operation protects both the capacitor and nearby motor windings.
• Epoxy filling improves shock resistance, which matters for motors that vibrate during operation.
• Good overload capability gives a margin against short-term current rises and voltage fluctuation.

Technical Specifications:
• Model: CBB60; Capacitance: 12uF + 4.2uF (two sections); Rated voltage: 450V; Safety class: S0
• Case and terminals: aluminum case with insert (push-on) terminals
• Loss tangent tanδ ≤ 0.2% (20°C, 100Hz).
• Terminal-to-terminal test: 2.0Un for 2 seconds, with no flashover or permanent breakdown.
• Terminal-to-case test: at least 2100VAC for 2 seconds, with no dielectric breakdown or flashover.

Typical Applications:
• Evaporative air coolers with a fan motor plus an auxiliary drive.
• Ventilation units whose motors use main and auxiliary windings.
• Small appliance motors in household and light commercial equipment.

Selection and Replacement Tips:
• The 4.2uF value is non-standard, so match it exactly rather than rounding to 4uF or 5uF.
• Always compare capacitance (uF), rated voltage (V) and terminal type with the original part.

Why Buy from Cixi Riyi:
• Quality systems: the factory holds ISO9001 and ISO14001 certification, and the product range carries approvals such as CQC, TUV, VDE, IMQ, UL and CE; ask which certificate applies to this model.
• Quick cross-reference: send nameplate photos or a sample and we will confirm the match and quote.
