Solar / Photovoltaic Electric Power System Connector

One unit = one male connector + one female connector, self-lock waterproof design

NOCO-SC-4 connector is designed to make wiring of variable electrical power systems (maximum current rate of 30A) much simpler and faster, typical applications including solar arrays interconnection, remote communication, wind turbo power generator power distribution grid, etc. We supply also the crimp tool kit for NOCO-SC-4 connectors, 3-way T-type adapter 4-way T-type adapter and pre-wired NOCO-SC-4-PV1-F1 solar power cable.

Specifications:

• Protection class: IP67
• The wrench tool is available:
  • 2 (1 pair) spanners for 10 - 200 pairs connector
  • 4 (2 pairs) spanners for 500 pairs connector
  • 8 (4 pairs) spanners for 1000 pairs connector
  • 16 (8 pairs) spanners for 2000 pairs connector
• Suitable wire sizes & rated current:
  • 2.5 mm² (AWG14): 12A
  • 4.0 mm² (AWG12): 20A
  • 6.0 mm² (AWG10): 30A
• Quick & simple assembly processing and simple removal of plugs without the aid of any extra instrument
• Compatible with PV (photovoltaic) cables with different insulation diameters
• Withstanding voltage: 1000V
• Contacting resistance: ≤ 0.5 mΩ
• Insulating resistance: ≥ 500 MΩ
• Anti-flame class: UL94-VO
• Wiring method: cold press
• Contact material: Silver plated copper
• Insulation material: Polycarbonate (PC) / Polyamide (PA, Nylon), black
• Environmental temperature range: -40 °C ~ +90 °C
• Insertion force: ≤ 50N; Withdrawal force: ≥ 50N

NOCO-SC-4 connectors are single-contact electrical connectors commonly used for linking electric devices (typical application: connecting solar panels). NOCO-SC-4s allow strings of panels to be easily constructed by pushing the connectors from adjacent panels together by hand, but require a tool to disconnect them to ensure they do not accidentally disconnect when the cables are pulled. The NOCO-SC-4 and compatible products are now universal in the solar market today, equipping almost all solar panels produced since about 2011. NOCO-SC-4 connectors are rated at 1000 V, which allows longer strings to be created.

The NOCO-SC-4 system consists of a plug and socket design. Oddly, the plugs and sockets are placed inside plastic shells that appear to be the opposite gender - the plug is inside a cylindrical shell that looks like a female connector but is referred to as male, and the socket is inside a square probe that looks male but is electrically female. The female connector has two plastic fingers that have to be pressed toward the central probe slightly to insert into holes in the front of the male connector. When the two are pushed together, the fingers slide down the holes until they reach a notch cut into the side of the male connector, where they pop outward to lock the two together. For a proper seal, NOCO-SC-4s require the usage of a cable with the correct diameter. Normally double-insulated (insulation plus black sheath) and UV resistant (most cables deteriorate if used outdoors without protection from sunlight). Connection is made by use of a special crimping tool, alternatively by soldering.

Your attention please, the NOCO-SC-4 connector is UL rated at 20 A and 600 V maximum, depending on the conductor size used. But in Europe, standards efforts also allow 1000V versions.

Safety caution: though NOCO-SC-4s' constant spring pressure provides reliable low resistance contacts. However, it is very important to never connect or disconnect them under load, even on low-voltage (12-48 V) systems. An electric arc may form which can melt and seriously damage contact materials, resulting in high resistance and subsequent overheating. This is partly because direct current (DC) continues to arc, whereas commonly used alternating current (AC) more readily self-extinguishes at the zero-crossing voltage point. Large arrays of panels are commonly interconnected in series, made of strings of panels generating 17 to 34 V each, with overall voltages up to 600 V per string. Interruption requires a special DC circuit breaker which allows opening the circuit without arc damage.
