Suntree 6mm Single Core Solar Cable is a premium wiring solution specifically designed for the high-voltage and high-temperature demands of photovoltaic systems. Rated for 1500VDC, this cable features dual-wall insulation and electron beam cross-linked technology for maximum durability. It is halogen-free, flame retardant, and offers excellent resistance to UV radiation, ozone, salt, and general weathering. With a high current-carrying capacity and a wide operating temperature range from -40℃ to +90℃, this cable is available in black and red for easy identification of positive and negative strings during installation.

The Suntree 4-Pole DC Miniature Circuit Breaker (MCB) is a specialized safety device engineered for high-voltage solar photovoltaic systems operating up to 1000VDC. Available in current ratings of 20A, 32A, and 63A, this 4-pole breaker provides advanced isolation by breaking both the positive and negative lines across multiple stages. This configuration is essential for large-scale arrays where high DC voltages require robust arc-quenching capabilities. It features standard 35mm DIN rail mounting, making it compatible with most solar distribution boards and combiner boxes while ensuring long-term protection against overcurrent and short-circuit faults.
