Description
The FAB‑MC4B Solar Branch Connector from Fibramérica is designed to simplify and enhance parallel connections in photovoltaic (PV) systems. Ideal for integrating multiple PV panel strings into a unified array, this robust connector supports various branch types including 2-1, 3-1, 4-1, 5-1, and 6-1 configurations.
Manufactured with high-grade PPO insulation and tin-plated copper contacts, the FAB‑MC4B offers excellent conductivity and durability. It supports up to 30A of current and is rated for 1000V under TUV and 600V under UL standards, making it reliable for a wide range of residential, commercial, and industrial solar installations.
Its keyed housing ensures secure mating, and the connector allows multiple cycles of plugging and unplugging without compromising performance. Thanks to its IP67 rating and UL94-V0 flame retardancy, the FAB‑MC4B is built to withstand harsh environmental conditions, ensuring long-term reliability and system safety.
Perfect for solar professionals, this connector is a vital component for optimizing solar panel layouts with safe and streamlined multi-string connections.
