INDUSTRIAL SWITCHING COMPONENTS. FACTORY DIRECT.

Complete Load Switching Solutions for Industrial Equipment Manufacturers

Modern industrial equipment rarely handles just one type of circuit. Engineers frequently have to mix high inrush inductive motors, heavy capacitive banks, and specialized direct current lines inside their designs. KRIPAL solves this sourcing headache by manufacturing a fully coordinated control portfolio. Our factory controls the entire manufacturing process using premium silver alloy contacts and optimized magnetic coils to guarantee stable drop out times, low heat dissipation, and dependable performance across all utilization categories.

Complete Load Switching Solutions for Industrial Equipment Manufacturers

Custom Motor Control and Protection Assemblies

We configure our switching components and overload relays to simplify assembly and prevent common field failures. Our hardware directly solves your real-world panel bottlenecks:

  • Prevent Contact Welding: Our AC and DC contactors use heavy silver alloy contacts to quench electrical arcs during frequent motor cycles before they can damage your hardware.
  • Lock Out Short Circuits: Our reversing combinations rely on physical mechanical interlocks and auxiliary cutouts, preventing both contactor groups from closing together during rotation changes.
  • Eliminate False Tripping: Our thermal overload relays use temperature compensation strips to ensure bimetallic elements react strictly to actual motor faults, preventing nuisance trips in hot outdoor panels.
  • Absorb Voltage Surges: For capacitor switching, our contactors use early make terminals wired with damping resistors to absorb massive current spikes before the main contacts close.
  • Save Installation Space: We manufacture mini contactors rated up to 32A alongside snap on auxiliary blocks, letting you fit full motor control into crowded enclosures with strict space limits.

Frequently Asked Questions

Explore FAQ >
A relay is typically used for switching control or signal-level circuits, while a contactor is designed to switch higher current loads such as motors, heating elements, and power circuits. Contactors are commonly used in industrial and commercial applications where frequent switching is required.
Selection depends on the load type, rated current and voltage, control coil voltage, number of poles, and the application environment. For motor applications, factors such as starting current and duty cycle should also be considered.
Yes. We supply AC contactors for general power switching, motor control, and HVAC systems, as well as DC contactors for battery systems, DC motors, and DC control circuits.
Reversing contactors are used to change motor rotation direction by reversing the phase sequence. They are commonly applied in conveyors, hoists, elevators, gates, and other equipment requiring forward and reverse operation.
Thermal overload relays are used to protect motors from overload and phase-loss conditions. They are typically paired with contactors in motor starter assemblies to help prevent motor damage.
Yes. Miniature contactors are designed for space-limited panels and lower current applications, typically from 9A to 32A. They are widely used in control panels, HVAC units, and compact OEM equipment.
Yes. Our contactors and relays are manufactured in accordance with IEC and other applicable international standards, supporting safe and reliable operation across global markets.
Auxiliary contacts can be added to provide status indication, interlocking, and feedback signals within control circuits.
