Wide Application Range

1. OEM matching medium-load 5pin SPDT mini relay spare part for Scania/Iveco heavy trucks and small 24V diesel gensets, dual medium-load switching control for fan, fuel pump, preheating and dual-circuit alarm circuits
2. Direct replacement for failed original 0331801300 OEM relay: dual-circuit auxiliary electrical equipment switching failure, intermittent power loss and circuit overheat malfunction
3. Universal core stock for Scania/Iveco heavy truck special repair shops and 24V generator rental companies for daily 24V heavy vehicle & 24V genset dual-circuit overhaul
4. Safety control system upgrade retrofit for 24V mini gensets and heavy commercial vehicles, upgrade stable 30A/15A dual-path SPDT switching protection function with mounting tab for exposed wiring installation slots

Common Equipment Failures Solved

• Cheap generic 20A 5pin 24V relays have thin contacts, severe melting ablation under 30A medium dual load, leading to fan stall, fuel pump shutdown and vehicle overheat warning malfunction
• Inferior thin plastic mini housing cracks under long-term heavy truck severe vibration, internal coil breakage causing total loss of dual-circuit switching control function
• Mismatched 12V relays burn coil instantly after installation, unable to operate normally
• Relays without mounting tab cannot be fixed for exposed wiring environments, loose wiring leads to intermittent power failure
• Original Bosch 0331801300 5pin SPDT medium-duty mini relay damaged, direct plug-and-play replacement without harness modification
• Heavy 24V truck/24V genset requires dedicated 5pin SPDT changeover relay for dual-circuit switching; 4pin single normally open relays cannot realize automatic switching between two circuits
