Enphase 3-Phase Q Cable Male Field Wireable Connector

The Enphase IQ Field Wireable Three-Phase Male Connector (part number Q-CONN-3P-10M) is the male-gender field-wireable connector for three-phase Enphase Q Cable and IQ Cable installations. Designed for the sixth-generation Enphase IQ System, these connectors allow installers to terminate raw three-phase cable on-site without pre-made assemblies — providing maximum flexibility in three-phase microinverter array layouts. Compatible with conductor cross-sections from 2.5mm² to 6mm² and cable outer diameters of 8–21mm, the Q-CONN-3P-10M is rated to 690V AC and 25A with a minimum IP67 protection class. 690V AC Rated Voltage 25A Rated Current IP67 Protection Class -40 to +110°C Temperature Range ⚠ Never Connect or Disconnect Under Load: The Q-CONN-3P-10M connectors are not load-break rated. Always ensure the Enphase system AC power is fully disconnected before mating or separating connectors. Connection or disconnection under load may cause arcing, damage, or serious injury. ⚠ Phase Assignment: When assembling the connector, match conductors to the correct L1, L2, L3, and Neutral terminals as labelled on the contact carrier. Incorrect phase assignment will affect the phase balance of the three-phase microinverter circuit and may cause system faults. ℹ Crimping Tool Required: Assembly of three-phase field wireable connectors requires a Multi-Contact PV-compatible crimping tool. For flexible wires, Enphase recommends using ferrules before insertion into the contact carrier for a secure, corrosion-resistant termination. End-Feed & Center-Feed Capability A mated pair of Q-CONN-3P-10M (male) and Q-CONN-3P-10F (female) connectors enables end-feeding of the branch circuit with an AC supply connection from raw cable. A male connector can also be used with appropriate adapter cables to center-feed the branch, giving greater layout flexibility in complex rooftop arrays. Cable Waste Elimination By allowing on-site termination of raw Q Cable to the exact length needed, field wireable connectors eliminate the need for pre-made cable assemblies of fixed lengths. This reduces cable waste on site, simplifies logistics, and allows arrays positioned in multiple roof sections or buildings to be connected without excessive cable runs. Broad Cable Compatibility The connector accepts cable outer diameters of 8 to 21mm and conductor cross-sections of 2.5mm² to 6mm², covering the full range of three-phase Q Cable and standard homerun cable gauges typically used in IQ Microinverter installations across the UK and Europe. IEC 61984 & IP67 Certified Certified to IEC 61984 (connectors for low-voltage circuits) with a minimum IP67 weatherproof rating and a temperature resistance of 90°C wet and dry. The Australian/Enphase product page also notes IP66/IP68, confirming the connectors comfortably exceed IP67 requirements — suitable for fully exposed rooftop use.

The Q-CONN-3P-10M is the three-phase version for use with three-phase Q Cable carrying L1, L2, L3, and Neutral. The Q-CONN-10M is the single-phase version for standard two-wire single-phase Q Cable. Ensure you order the correct connector for your cable type. Do I need to buy the male and female connector separately? Yes. The Q-CONN-3P-10M (male) and Q-CONN-3P-10F (female) are sold individually. For an end-feed or junction connection, you will need one of each. Both are available from AIZO Quality Heating. What tool do I need to disconnect a mated three-phase connector pair? Use the Enphase Q-DISC-3P-10 disconnect tool, which is the three-phase specific disconnect tool. The single-phase Q-DISC-10 is not suitable for three-phase connector bodies. Can I use these connectors with standard market three-phase cable, not just Enphase Q Cable? Yes — provided the cable has a conductor cross-section of 2.5mm² to 6mm² and an outer diameter of 8–21mm. The connectors are compatible with Enphase raw three-phase Q Cable or equivalent homerun cable of suitable specification. Always follow the Enphase three-phase Q Cable design guide for maximum circuit lengths and current limits.
