CNC MC4 Connector with 20A Fuse DC 1000V | Safe Solar Power Connection

Built-In Fuse Protection Right at Your Solar Panel

The CNC MC4 Inline Fuse Connector combines a standard MC4 connection with a 20A DC fuse inside a sealed housing. It protects each solar string from overcurrent and reverse current faults, so one bad panel or short circuit can't damage your cables, inverter, or the rest of your system. No extra fuse box needed: just plug it inline and you're protected.

Key Features

• Integrated 20A DC fuse for string-level overcurrent protection
• Rated DC 1000V for residential and commercial solar systems
• Field-replaceable fuse: unscrew the housing to change the fuse, no need to replace the whole connector
• IP68 water & dust proof with red rubber seals, built for Pakistan's heat, dust, and monsoon
