Capacitor Switching Contactor

A KRIPAL Capacitor Switching Contactor is a specialized device engineered for the reliable switching of 3-phase, single or multi-step capacitor banks in Power Factor Correction (PFC) systems. Its primary role is to automatically connect and disconnect capacitors to compensate for reactive power in electrical grids. This optimizes the power factor, reduces energy losses, stabilizes voltage, and is essential in industrial power distribution, commercial buildings, and critical power facilities.

Switching capacitors creates a massive inrush current that can be 10-20 times the steady-state current. Standard contactors cannot handle this surge and would suffer from contact welding and rapid failure. KRIPAL Capacitor Contactors, like the UKC1 (D)-C model, are specifically engineered to solve the problem of high inrush current, preventing switching overvoltages and arc damage for reliable, long-lasting operation.

KRIPAL Capacitor Contactors are designed and tested to meet rigorous international safety and performance standards, including IEC 60947-4-941. This ensures global compliance, high reliability, and safe operation in your power correction systems.

• Efficient Inrush Suppression: Effectively limits high inrush currents during capacitor charging/discharging.
• Enhanced System Reliability: Prevents contact welding and arc damage, ensuring stable performance.
• Reduced Energy Costs: Optimises the grid power factor, directly reducing line losses and avoiding utility penalties.
• Long Service Life: Manufactured with high-quality materials and precise craftsmanship for superior durability and a long operational lifespan.

To meet diverse application needs, KRIPAL offers a wide selection:

• Rated Currents: A broad range from 9A to 85A, capable of handling capacitor banks of various capacities.
• Coil Voltages: Multiple standard options, including AC24V, AC48V, AC220V, and AC380V for easy integration with different control power sources.

They are the ideal component for reactive power compensation in a wide range of scenarios:

• Industrial Power Distribution: In PFC panels for low-voltage systems to compensate for inductive loads from motors and machinery.
• Commercial Buildings: In electrical distribution boards of shopping malls and office towers, to stabilize voltage and reduce transmission losses.
• Critical Power Facilities: Ensuring reliable operation of capacitor systems in demanding environments like new energy power stations and data centers.
• Public Infrastructure: Optimising power efficiency in municipal projects and rail transit power supply networks.

When selecting a KRIPAL Capacitor Contactor, consider:

• Capacitor Bank Current: Choose a model with a rated current (9A-85A) that matches or exceeds your capacitor bank's requirements.
• Control Voltage: Select a coil voltage (e.g., AC24V, AC380V) that matches your control circuit.
• System Voltage: Ensure the contactor's rated insulation voltage is suitable for your main power supply.
• Application Environment: Consider the specific demands of your facility, whether it's industrial, commercial, or a critical infrastructure project.
