ABB EF370 Overload Relay

ABB EF370 Overload Relay

Product Description :

• • It is an electrical protection device use to protect motors and other electrical equipment from damage due to overheating.
  • It contains a thermal element or bimetallic strip that is sensitive to temperature changes. When current flows through the motor, the thermal element heats up. If the current exceeds the rated value or the motor experiences an overload condition, the temperature of the thermal element rises.
  • It is a type of protective relay that monitor the temperature of the motor or equipment and interrupts the power supply if it detects excessive heat.
  • It is connected in series with the motor’s power supply. It contains a current sensing element, such as a bimetallic strip, heater coil, or electronic sensor, that detects the current passing through the motor circuit.

  • An Overload Relay is an electrical protection device designed to safeguard motors and electrical circuits from damage caused by excessive current or overheating. It automatically interrupts the circuit when current exceeds a preset limit, preventing motor burnout, equipment failure, and fire hazards.

  • Constructed with high-quality metals, durable contacts, and precise thermal or electronic sensing elements, overload relays are engineered for reliable performance, long service life, and accurate response. They are commonly used in industrial machinery, HVAC systems, pumps, compressors, and motor control panels.
