Cbb65 60+5uf 450v S2 UL Explosion-Proof Aluminum Housing 2+3+4 terminal

This CBB65 60+5μF 450V starting capacitor is a core electrical component in air conditioning and refrigeration equipment.  It features a typical dual-capacitance design, primarily used to ensure the synchronous starting and stable operation of the compressor and condenser fan. Its all-aluminum casing structure, combined with an industrial-grade S2 explosion-proof rating, provides extremely high reliability in complex power grid environments and high-load operating conditions.

Core Parameters and Application Logic
The dual-capacitance configuration (60+5μF) uses a three-terminal (C/HERM/FAN) layout.  Through two internally integrated independent capacitor units, it simultaneously drives the compressor (60μF) and the fan (5μF) with a single component. This integrated design effectively optimizes wiring space within the electrical control box.

S2-level Mechanical Explosion-Proof Safety Standard: The aluminum casing contains a pressure-sensitive circuit breaker. When the capacitor generates internal pressure due to overload or aging, the top sealing cover will physically deform and actively disconnect the internal circuit, preventing casing rupture, complying with UL safety standards and S2 protection requirements.

Metallized Film Self-Healing Characteristics: The internal dielectric material possesses excellent self-healing properties. Even when subjected to instantaneous overvoltage breakdown, the surrounding metal plating quickly vaporizes to restore insulation, ensuring that the capacitor does not fail directly due to minor breakdowns, significantly extending the equipment's service life.

Impact Resistance and Low-Loss Architecture: The product features an extremely low dielectric loss angle (Tan δ) and high insulation resistance, resulting in very low heat generation under high current surges and continuous overload conditions. Its performance output is stable, effectively improving the power factor of the motor and enhancing the overall operating efficiency of the equipment.

Industrial-Grade Terminal Interface (2+3+4 Pins):  The quick-connect terminal design, with 2, 3, and 4 pin layouts, is polarity-optimized for on-site installation, ensuring stable contact for high-current conduction. It is widely compatible with mainstream commercial and household air conditioners, dryers, and other inductive load equipment.
