WG9716582301+009/1 Relay for HOWO Truck 40A Normally Open
The WG9716582301+009/1 40A Normally Open Relay is engineered specifically for heavy-duty HOWO trucks, serving as a critical component in the vehicle’s electrical system. This high-capacity relay precisely controls the flow of electricity to essential accessories including headlights, wiper motors, and auxiliary power systems. Designed to withstand the rigorous demands of commercial transport, its normally open configuration ensures circuits remain inactive until deliberately energized, preserving vehicle battery life during extended idle periods.
Robust Construction for Commercial Vehicles
Featuring military-grade terminals and sealed construction, this HOWO-compatible relay resists vibration-induced failures common in long-haul trucking applications. The reinforced contact points maintain stable connectivity under 40A continuous load conditions, with short-term surge tolerance reaching 120A. This capacity makes it suitable for controlling high-current accessories like winches or refrigeration units without voltage sag or contact welding. Manufactured under strict ISO standards, each unit undergoes precision calibration for consistent switching response times between 8-12 milliseconds.
Reliability Across Extreme Conditions
Truckers operating in diverse environments require components that perform reliably from arctic cold to desert heat. The WG9716582301+009/1 relay operates flawlessly in temperature ranges from -40¡ãC to +105¡ãC, with specially formulated insulation materials that resist thermal degradation. An advanced arc suppression design minimizes contact erosion, extending service life to over 100,000 operational cycles. This durability is critical for fleet managers needing to minimize roadside breakdowns and unscheduled maintenance. The flame-retardant housing meets UL94-V0 specifications, adding an essential safety layer in electrical fault scenarios.
Optimized Circuit Design
Unlike generic alternatives, this relay incorporates noise-suppression diodes that eliminate voltage spikes affecting sensitive truck electronics. The electromagnetic coil is wound with oxygen-free copper for minimal resistance and stable coil inductance. This precision engineering results in remarkably low power consumption – just 2.2W during activation – reducing alternator load and improving fuel efficiency. Clear polarity markings and industry-standard terminal numbering ensure technicians can perform correct installations and replacements within minutes, decreasing workshop turnaround times.
Application Versatility
Compatible across multiple HOWO platforms including A7, T7, T5G, and TX series, this 40A relay serves as a universal solution for various circuit control needs. Whether managing auxiliary lighting systems on dump trucks or plow controls on winter service vehicles, the normally open configuration provides operational flexibility. OEM engineers recommend replacement every 200,000 km as preventive maintenance – significantly extending the lifespan of connected components. For vocational applications like cement mixers or crane operation, this relay delivers dependable performance where electrical stability directly impacts job completion.
Precision Manufacturing Quality
Every WG9716582301+009/1 unit is manufactured with computer-controlled insertion equipment that ensures terminal positioning accuracy within 0.1mm tolerance. Post-production testing includes automated load cycling at 125% rated capacity, vibration simulation, and thermal shock validation. Batch traceability through laser-etched QR codes guarantees authenticity and simplifies warranty claims. This attention to detail makes it the preferred choice for both original equipment installation and aftermarket replacement.
Installation Simplified
Designed for compatibility with standard waterproof connectors, this relay integrates smoothly into existing wiring harnesses without modifications. The compact dimensions (38mm x 28mm x 35mm) provide ample clearance in densely packed underhood fuse boxes. Color-coded terminals match industry wiring conventions: 85-coil ground, 86-coil positive, 30-power input, 87-output to accessory. Clear documentation included with each unit minimizes installation errors that cause nuisance fuse blowouts or circuit failures.
Maintenance Advantage
The hermetically sealed WG9716582301+009/1 relay requires no routine servicing, resisting moisture intrusion and environmental contamination that degrade conventional relays. Truck maintenance facilities report significantly reduced electrical troubleshooting hours when transitioning fleets to these sealed units. Spare stock recommendations vary by fleet size: operators maintaining 1-5 trucks should carry two units, while large fleets benefit from keeping 5% of vehicles in spare parts inventory.
Durability Economics
Over an average commercial vehicle service life, premium relays prevent multiple electrical system failures that create cascading expenses. Consider: one avoided towing incident covers the cost premium over inferior alternatives fifteenfold. The superior WG9716582301+009/1 construction reduces premature contact failure that causes parasitic battery drain – a common cause of no-start calls in cold weather. Total cost of ownership analysis proves this relay delivers value beyond initial purchase through reduced downtime and extended service intervals.
This WG9716582301+009/1 relay represents the convergence of reliability engineering and practical application knowledge gained from thousands of HOWO trucks operating globally. Its specifications exceed industry norms because commercial vehicles demand components built beyond standard automotive tolerances.
Operators consistently report improved electrical system stability after upgrading to the WG9716582301+009/1, particularly in auxiliary circuits prone to voltage fluctuations. The relay’s intelligent design prevents coil burnout despite irregular input voltages, a common challenge when alternators approach end-of-life. For mixed-fleet maintenance operations, standardizing on this unit creates inventory efficiencies while elevating reliability across all equipment types.
Technical Integration Features
Cross-platform testing confirms seamless compatibility with both analog control systems in earlier models and CAN bus interfaces in newer HOWO truck generations. This forward-compatibility protects investments by ensuring spare parts remain viable across model transitions. The WG9716582301+009/1 unit integrates diagnostic capabilities by maintaining stable coil resistance values (75¡À3¦¸) that facilitate quick circuit testing with standard multimeters.
Performance Enhancement
Independent tests measuring contact voltage drop show less than 80mV loss at rated load conditions, superior to the 150mV industry average. This efficiency translates directly to brighter lighting and faster accessory operation.
Operational Security
The vibration-resistant design absorbs harmonic frequencies from rough terrain operations, eliminating contact chatter that causes unreliable accessory operation. This stability is crucial for safety-critical functions.
Distribution centers throughout Asia, Europe and Africa maintain consistent WG9716582301+009/1 inventory to serve both retail customers and fleet maintenance facilities. When ordering replacements, technicians should always verify relay specifications match OEM requirements for uninterrupted performance. Proper installation follows specific torque guidelines: terminal fasteners require 1.8-2.2 N.m tightening force to establish optimal electrical contact without damaging terminal posts.
