Mining & Mineral Processing

Powering Productivity in Extreme Conditions

Mining and mineral processing operations demand electrical systems that perform reliably in some of the harshest environments on Earth. From deep underground tunnels to open-pit extraction sites and high-dust crushing facilities, equipment must operate continuously under vibration, heat, and moisture without compromising safety.

Kripal Electric provides rugged, certified low-voltage protection and switching solutions built to withstand these conditions. Designed for heavy-duty performance and long-term reliability, Kripal’s components ensure safe, stable, and efficient power distribution for the mining industry’s most demanding electrical systems.

Industry Challenges

Electrical systems in mining environments face a combination of extreme challenges that test the limits of durability and safety. Constant exposure to abrasive dust, vibration, humidity, and corrosive agents accelerates wear and can lead to insulation degradation if components are not engineered for such conditions. Heavy machinery such as crushers, conveyors, and pumps run around the clock at high currents, where even minor electrical faults can result in costly downtime and production losses.

Safety is another major concern, as electrical hazards rank among the most serious risks in mining. Compliance with strict isolation, ingress protection, and emergency shutdown standards is therefore essential. These operations often take place in remote locations where maintenance is logistically difficult and costly. Together, these challenges require equipment that can perform with consistency, resist environmental stress, and maintain safety standards across years of continuous operation.

Kripal’s Mining & Mineral Processing Solution

Heavy-Duty Circuit Protection

Kripal’s MCCBs and ACBs provide robust protection for high-current circuits powering heavy machinery and substations. Rated up to 800A and built to IEC 60947-2, these breakers offer high breaking capacities and adjustable trip settings, ideal for feeders, transformers, and large motors. Miniature Circuit Breakers (MCBs) safeguard lighting, control, and auxiliary systems with precision and compact design, ensuring selective coordination throughout the distribution hierarchy.

Isolation and Safety Switching

For maintenance and emergency shutdown, Kripal’s Load Break Isolators and Enclosed Rotary Disconnects deliver safe and visible isolation points.

• IP66/IP67 weatherproof enclosures resist dust, moisture, and chemical exposure.
• Lockable handles and padlock options provide secure operator control.
• Built to IEC/EN 60947-3, ensuring compliance with industrial safety codes.

These isolators are ideal for conveyor sections, crusher stations, and field-mounted equipment where safety and accessibility are crucial.

Motor Control & Automation

Mining and processing plants rely heavily on electric motors for conveying, crushing, ventilation, and pumping. Kripal’s AC contactors, overload relays, and control relays ensure smooth startup, precise control, and overload protection.

• Designed for high endurance (>1 million mechanical operations)
• Compact DIN-rail form factor for control panels
• Suitable for integration with automated motor control systems and PLCs

Environmental Protection & Durability

All Kripal devices used in mining applications feature UV-stabilised, flame-retardant materials (UL94-V0) and are available in IP65–IP67 rated enclosures.

These components resist abrasive dust, conductive particles, vibration, and thermal stress, ensuring reliability in both surface and underground installations.

Power Connectivity & Portable Systems

Kripal’s industrial plugs, sockets, and switch-socket combinations provide safe, flexible power connections for mobile tools, portable equipment, and temporary installations.

• Heavy-duty 56 series connectors rated up to 63A
• Resistant to impact, oil, and corrosion
• Compliant with IEC 60309 standards for industrial-grade connections
