12V Starter Solenoid 6659319 for Bobcat 310 371 440 450 500 540 542 543 630 631

The ​​Keliejnese Starter Solenoid (Part #6659319)​​ is engineered for Bobcat compact loaders and excavators (310, 371, 440, 450, 500, 540, 542, 543, 630, 631), delivering instant engine ignition via high-permeability alloy cores and oxidation-resistant copper coils in 12V circuits. Its dual-contact design handles 300A surge currents, eliminating voltage drops and startup delays even in sub-zero temperatures. With an IP65-rated sealed housing, it resists mud, dust, and moisture ingress, ensuring longevity in construction sites and mining operations. Direct compatibility with OEM wiring harnesses allows tool-free installation within minutes, minimizing equipment downtime. Each unit undergoes 20,000-cycle endurance tests and -30°C cold-start validation, providing dependable power control for heavy-duty machinery.

• 300A Surge Current Handling​​---Dual silver-alloy contacts transmit 300A surge currents without voltage drop, enabling reliable cold starts at -20°C and protecting starters from wear.
• IP65 Sealed Protection​​---Epoxy encapsulation and rubber seals block contaminants in mining/construction sites, extending service life by 200% under harsh conditions.
• Direct OEM Harness Fit​​---Plug-and-play compatibility with factory connectors enables 15-minute replacement—no wiring modifications or special tools required.
• -30°C to 125°C Operation​​---Thermal-stable coils and low-temperature grease ensure <0.1s response across -30°C to 125°C, ideal for seasonal extremes.
• Multi-Model Compatibility​​---Precisely engineered for Bobcat 310-631 series, passing EMC tests to prevent electrical interference in complex circuits.
