Hitachi excavator accessory 4255762 relay; storage battery

The Hitachi excavator 4255762 relay is the core control component of the starting circuit for medium and large excavators such as ZX200-3, ZX210-3, ZX240-3, ZX330-3, ZX450, etc. It directly controls the connection and disconnection of the battery and engine starting motor. Adopting high-strength electromagnetic coils, precision contact pads, high-temperature resistant ceramic insulators, and shockproof metal shells, the rated voltage is 24V, the current carrying capacity is strong, the contact closure is reliable, anti shake, anti pollution, and corrosion-resistant. Perfectly solves faults such as battery failure to connect, weak starting, inability to start, engine failure to start, machine failure to ignite, and inability to enter working mode (highly related to the "stall" protection mode after the failure of the high-pressure common rail pressure sensor).
