3G5A2-OF311

The 3G5A2-OF311 controller is an accessory designed to protect motors against high currents, resulting from short circuit conditions. It reacts in microseconds to detect a fault in the motor and protects it by tripping its circuit. The 3G5A2-OF311 is suitable for single phase alternating current motors, which are widely used in domestic and commercial applications.

Application Field

The 3G5A2-OF311 controllers are used in applications such as compressor motors, fan motors, pool motors, and pumps. In each of these applications, the controllers protect the motor from excess current. Other uses include commercial laundry machines, cash registers, vending machines, and office equipment.

The 3G5A2-OF311 controller is also suitable for single-phase motors used in heating and air-conditioning systems. This includes residential Heat Pumps, Air-to-Air Heat Pumps, and Room Air Conditioners. In the case of single-phase A/C compressors, the 3G5A2-OF311 is suitable, provided that the motor has the required terminal box connections.

Working Principle

The 3G5A2-OF311 controller works by detecting a fault in the motor\'s circuit. If the current flow is found to be too high, the controller will trip the circuit, disconnecting the motor from the power source, and protecting it from damage. To do this, the controller contains a magnetic switch with a thermal relay. The relay monitors the flow of current, and when it exceeds a certain threshold, the contacts open and the power is disconnected.

The magnetic switch is designed to operate quickly, so it can respond to a fault in a fraction of a second and disconnect the power before the motor can be damaged. The 3G5A2-OF311 is available in various current ratings, adapted for the type of motor or application. This protects the motor against the high currents that can damage it.

The 3G5A2-OF311 is an advanced and cost-effective solution for protecting motors against excess currents. Its fast reaction time ensures that the motor is always protected, and its easy installation and use make it an ideal choice for many applications. It can be used in both domestic and commercial applications, giving users peace of mind.
