Frequently Asked Questions
Q: What is an electric air compressor capacitor box and what does it do?
A: An electric air compressor capacitor box (also called a capacitor junction box or motor shell) is a protective housing that encloses the start or run capacitor of a single-phase motor. It shields the capacitor from physical damage, dust, and moisture, and organizes the electrical connections for safe, reliable compressor operation.
Q: What are the dimensions of this capacitor junction box?
A: This capacitor box measures 195 × 126 × 65 mm and is made from durable impact-resistant plastic in a black finish, making it suitable for most standard single-phase air compressor motor housings.
Q: How is the capacitor box installed on an air compressor?
A: Installation is straightforward — the housing includes screw holes on the sides that allow you to mount it directly onto the compressor motor's connection bolt. This design enables quick, hassle-free installation or replacement, reducing maintenance downtime significantly.
Q: Is this capacitor box compatible with my single-phase air compressor?
A: This junction box is designed for single-phase electric motor air compressors. Before purchasing, verify that your capacitor's physical dimensions fit within the internal cavity of 195 × 126 × 65 mm for a proper fit.
