YBR125 motorcycle starting relay, interface, current parameters and YBR125 starting system fully match, directly replace the original relay, no need to modify the circuit interface; Using copper terminal, strong conductive performance, can stably carry the large current load of the starting motor, to avoid excessive voltage drop during starting; The shell is made of flame retardant engineering plastics, and the internal contacts are wear-resistant. It is suitable for the working environment of high vibration and high temperature of the engine, and the long-term use is without contact ablation. Built-in overload protection structure, can prevent excessive current damage relay or start motor, improve electrical safety.
