GE IC2820D300H35 FIELD LOSS RELAY

الوصف

The GE IC2820D300H35 is a specialized field loss relay designed to protect DC motors from overspeed conditions caused by a loss of the motor’s magnetic field.

Technical Breakdown 🧠

A field loss relay monitors the current in a DC motor’s field winding. If the field current drops below a preset threshold—indicating a “field loss” condition—the relay’s contacts change state. The IC2820D300H35 is designed to perform this vital protective function. When a field loss occurs, a DC motor can accelerate uncontrollably, potentially leading to catastrophic mechanical failure. This relay senses that condition and immediately trips, typically opening the main contactor to shut down the motor safely.

The specific parameters of this model, including its current rating, are defined by the full part number, ensuring precise and reliable protection for the motor it’s applied to.

Applications 🏭

The IC2820D300H35 is a fundamental safety device used in:

• DC Motor Control Panels: Protecting large DC motors in applications like cranes, rolling mills, and elevators.
• Industrial Drives: Ensuring the safe operation of variable-speed DC drives.
• Heavy Machinery: Providing field loss protection for DC motors in industries like mining, paper, and steel.
