Arc Flash Relay

Sell-Best Arc Flash Relay Features

Sell-Best arc protection relay is designed to detect and rapidly and accurately respond to arc flash incidents for personnel and equipment electrical safety. Key Features include adopting advanced sensor technology for detecting various arc faults, supporting multiple communication protocols, Robust Design for harsh environments, Built-in self-diagnostics, compliance with safety standards, and comprehensive Protection such as arc flash protection, overcurrent, undercurrent, and ground fault protection.

Wide Applications of Sell-Best Arc Flash Relay

Sell-Best arc flash detection relays are used in various applications where there’s a need to protect electrical equipment and people from arc flash damage. Some common applications include:

• Switchgear cubicle: In switchgear, arc flash protection relays are mainly used to protect switchgear, busbars, feeders, etc. Once an arc fault occurs, the relay can quickly detect and send a signal to trigger a circuit breaker or other protection device, thereby isolating the fault area and preventing the accident from expanding.


• Transformer compartment: Our arc protection relay is mainly used to protect the transformer body, lead wires, bushings, etc. When a short circuit or ground fault occurs inside or outside the transformer, the relay can respond quickly to prevent the transformer from overheating or explosion.


• Motor control center bucket: In motor control center bucket, arc flash relays are mainly used to protect motors, soft starters, frequency converters, etc. When a short circuit or ground fault occurs inside or outside the motor, the relay can quickly cut off the power supply to prevent the motor from burning.


• Generator control panel: In generator control panel, our arc fault protection relay is mainly used to protect the generator, excitation system, protection relay, etc. When a short circuit or ground fault occurs inside the generator, the relay can quickly cut off the generator to prevent damage to the unit.
