ABB AO810 is an overload relay, which is an electrical protection device used to protect motors and other electrical equipment from damage caused by excessive current. It monitors the current flowing through the protected circuit and trips (interrupts the circuit) if the current exceeds a预设的安全 limit. Here are the product parameters, specifications, and application areas for the ABB AO810 in English:
Product Parameters:
Rated Current: The maximum current that the overload relay can carry without tripping.
Trip Current: The current level at which the relay will trip, typically a percentage of the rated current.
Time-Current Characteristic: The relationship between the duration of the overload condition and the current level that causes the relay to trip.
Reset Type: Whether the relay is manual reset (requiring manual intervention to reset the relay after a trip) or automatic reset (the relay resets itself after the overload condition is removed).
Operating Voltage: The voltage required to power the relay.
Specifications:
Physical Dimensions: The dimensions of the overload relay, including length, width, height, and weight.
Mounting Type: The method used to mount the relay, such as panel mount or DIN rail mount.
Environmental Rating: The relay’s resistance to environmental conditions such as temperature, humidity, and vibration.
Approvals and Certifications: Any safety or performance certifications that the relay has been tested and approved for, such as CE, UL, or IEC standards.
Application Areas:
ABB AO810 overload relays are widely used in the following areas:
Motor Protection: In industrial automation systems, overload relays protect motors from damage caused by excessive current due to overloads, short circuits, or ground faults.
Power Distribution: In electrical power distribution systems, overload relays monitor and protect circuits, preventing damage from excessive current.
Equipment Protection: Overload relays are used to protect various types of electrical equipment, such as pumps, fans, conveyors, and other industrial machinery.
Building Automation: In commercial and residential buildings, overload relays protect electrical systems from overloads, ensuring safe and reliable operation.
