Wide Application Range

1. OEM matching spare part for 24V heavy-duty vehicles and large diesel gensets, dual-circuit switching control for fan, preheating, fuel cut-off and alarm circuits
2. Direct replacement for failed original 0332204201 / V23234-A0004-Y052 relay: electrical equipment no start, intermittent operation, control circuit disorder, protection function failure
3. Universal stock for auto repair shops, machinery maintenance factories and generator rental companies for daily 24V heavy equipment overhaul
4. Retrofit safety control system for 24V generator units and construction vehicles to upgrade stable dual-path switching protection function

Common Equipment Failures Solved

• Cheap generic relays have unstable coil resistance, weak suction, contacts burn easily, leading to fan stop, preheating failure and generator overheat protection malfunction
• Inferior thin plastic housing cracks under long-term vibration, internal coil breakage causing complete loss of control function
• Mismatched 12V relays burn out coil immediately after installation, unable to work normally
• Original Bosch 0332204201 damaged, direct plug-and-play replacement without harness modification
• 24V heavy vehicle/generator needs dual-circuit switching control, 4-pin single-circuit relays cannot meet the control demand
