A Heavy Duty Resistance Box is designed to manage high power loads and provide robust control over electric motor-driven systems, particularly in demanding environments like EOT (Electric Overhead Traveling) cranes, industrial hoists, and other large machinery. It is used to regulate the motor's speed, smooth startup, and control current flow, ensuring the motor operates efficiently and safely.

Heavy Duty Dynamic Braking Resistors (DBR) are specialized resistors used in high-power electric motor systems, such as EOT cranes, industrial hoists, elevators, and other heavy machinery. They are designed to absorb and dissipate the excess energy generated during the braking phase of a motor’s operation, converting it into heat and ensuring safe, controlled deceleration. These resistors play a crucial role in dynamic braking, where mechanical energy is converted into electrical energy during deceleration.
