The Reason Why Copper Terminal Blocks Must Be Made Of Flame-retardant Materials

copper terminal block Generally, flame-retardant materials must be used to prevent the casing from igniting and causing a fire hazard under overload or short circuit conditions. copper distribution block Materials must meet international flame-retardant standards, such as UL94V0 or V1, to reduce the damage to surrounding components from melting or dripping adhesive. Flame-retardant materials must also possess good structural integrity to ensure that copper terminal strip materials maintain mechanical strength at high temperatures without cracking or collapsing. Using non-flame-retardant materials may lead to rapid failure under abnormal current conditions, resulting in more widespread system damage or increased repair costs.
