Contactor C130000812007 is a critical high-current electrical control component for Hydraulic Rock Drills. It excels in extreme mining environments—for instance, deep underground ore mines, high-altitude hard rock quarries, large-scale tunnel boring projects and dusty/humid construction sites.
These settings pose unique challenges for contactors: intense vibration (up to 40G), abrasive rock dust, occasional water ingress, voltage fluctuations, and temperature swings, which often cause contact ablation, coil burnout, or circuit failure. Yet, Contactor C130000812007 maintains uncompromised performance under all these harsh conditions. In fact, it directly addresses five core pain points that plague mining operations and lead to electrical system downtime.
First, its silver-nickel alloy contacts (contact resistance ≤0.01Ω) withstand 60A continuous current without ablation. This eliminates contact failure caused by arcing and dust accumulation. Second, the flame-retardant PA66 shell (UL94 V-0 rating) resists high temperatures and mechanical impact. Consequently, it ensures operational safety in high-heat or collision-prone mining environments. Third, its IP65 waterproof/dustproof rating blocks dust and water spray. Likewise, this prevents short circuits and internal component corrosion in dusty or humid work sites.
Fourth, the anti-vibration structural design (reinforced coil fixing + shock-absorbing base) withstands 40G vibration. Above all, this avoids loose connections and coil damage during high-intensity drilling, ensuring stable signal transmission. Fifth, the wide temperature adaptability (-40°C~120°C) and voltage tolerance (±10% of 24V DC) ensure reliable operation in extreme cold/hot conditions and unstable power supplies. On top of that, the overload protection function cuts off circuits automatically when current exceeds 75A, protecting expensive drill electrical components.
Unlike ordinary industrial contactors, this model is engineered for hydraulic rock drill’s harsh working conditions. To elaborate, the silver-nickel contacts have high arc-extinguishing performance, while the sealed coil design resists dust and moisture. Thus, it outperforms standard contactors in service life by 140%, significantly reducing electrical-related downtime.
Our manufacturing team uses precision injection molding + automated contact assembly technology. Furthermore, each unit undergoes current-carrying capacity testing (60A continuous) and vibration resistance verification. Additionally, the contactor undergoes 1 million-cycle switching trials to ensure long-term reliability.
Notably, it adapts to extreme temperatures from -40°C (high-altitude frozen mines) to 120°C (high-load electrical systems). Moreover, it passes 500-hour salt spray tests with no rust or contact oxidation. In addition, it endures 10,000-cycle overload tests without performance degradation.
The contactor’s bolt-on mounting design and standard terminal interface integrate seamlessly with mainstream Hydraulic Rock Drill electrical systems. It requires no circuit modifications or special tools for installation. As a result, maintenance teams can complete replacement in 10 minutes using standard electrical tools.
Our quality team conducts strict ISO 9001 verification for every unit. We perform contact resistance tests, current-carrying capacity trials, waterproof inspections and vibration resistance verification. Importantly, it complies with IEC 60947-4-1 international electrical contactor standards.
Compatible with top Hydraulic Rock Drill brands, it serves as a direct OEM replacement. Thanks to its reliability, it reduces contactor-related failure rates by 95%. Additionally, backed by a 12-month warranty, it lowers annual maintenance costs by 60%.
It not only ensures stable operation of drill electrical systems but also extends the service life of power units by 90%. Overall, Contactor C130000812007 delivers cost-effective, reliable electrical control for long-term mining operations. Beyond that, it minimizes downtime caused by electrical failures, maximizing operational efficiency and project profitability.
