Box Cap Wire Type 3.5UF

Description

The SENLU CBB61 3.5µF 450VAC Box-Type Motor Run/Start Capacitor is a high-performance electrical component designed to regulate speed, provide optimal starting torque, and maintain phase efficiency in small, single-phase alternating current (AC) fractional motors. Enclosed in a compact, pitch-sealed, flame-retardant rectangular resin case, this capacitor features two flexible, heavy-duty insulated wire leads for direct splicing into an appliance’s existing wiring harness. Engineered with advanced self-healing metallized polypropylene film, it operates reliably under continuous workloads up to 450V AC (50/60Hz) with a professional ±5% tolerance. The internal self-healing technology automatically isolates micro-faults caused by voltage surges, preventing sudden, permanent component failure and ensuring your everyday household and light commercial air-moving appliances run quietly, coolly, and efficiently. Key Features Precise 3.5µF Capacity: Tailored for slightly larger or high-velocity fan motors that require higher torque than standard 1.5µF or 2µF household fans. Flexible Wire Leads: Dual pre-stripped, insulated pigtail wires simplify installation—allowing you to easily twist, crimp, or splice directly into existing circuitry. High-Voltage Durability: Rated for up to 450VAC, making it completely backwards-compatible with 400V, 350V, or 250V configurations. Rugged Box Geometry: Space-saving rectangular CBB61 profile designed to handle continuous mechanical motor vibrations and thermal stress. Self-Healing Technology: Extends overall motor life by instantly correcting minor internal dielectric punctures caused by power grid spikes. Compatible Machines & Applications A 3.5µF wire-type box capacitor is a universal standard for heavy-duty residential and light commercial air-circulation equipment. It is the go-to replacement part for fixing equipment that hums, runs too slowly, or refuses to spin up on its own, including: 1. High-Performance Ventilation & Exhaust Fans Commercial Exhaust Fans: Commonly used in restaurant kitchen hood exhaust setups and heavy-duty building ventilation extraction units. Inline Duct Fans: Powers inline extraction and booster fans used in commercial HVAC ducting or residential indoor grow setups. Industrial Pedestal Fans: Regulates the multi-speed settings on heavy-duty, high-velocity oscillating workshop or garage floor fans. 2. Large Ceiling Fans & Domestic Air Movers Heavy-Duty Ceiling Fans: The textbook replacement size for large-blade or industrial-style ceiling fans (often found as a matching part option on Daraz.lk) that have lost their speed settings or struggle to start spinning. Evaporative “Swamp” Coolers: Drives the primary heavy-duty blower fan motor in mid-sized portable or window-mounted air coolers. 3. HVAC & Air Conditioning Units AC Indoor Blower Motors: Frequently used to power the multi-speed squirrel-cage blower fans inside the indoor evaporator units of mini-split climate control systems. Dehumidifiers & Air Purifiers: Powers the internal high-volume circulation blower fans that pull ambient air through dense HEPA filters or condenser coils. ⚠️ Installation Safety Tip: Even a small 3.5µF capacitor can hold a sharp, painful electrical sting long after the appliance has been completely unplugged. Always turn off the circuit breaker, unplug the machine, and use an insulated screwdriver to bridge the two bare wire ends together to safely discharge any residual electricity before handling the wires!
