Current monitoring relay, also called as overload protection device, is one of the most important signal input devices used in industrial monitoring systems. It monitors and controls current, voltage and other parameters of power systems and provides real-time data for precise operation and maintenance of the system.

The 35040028 is a current monitoring relay specially designed for monitoring AC current in a wide range of applications. It is capable of monitoring Line currents, Voltage, phase current and phase voltage. It features an adjustable operating range which ranges from 277VAC to 600VAC.

The 35040028 is easy to install and simple to use. It is also highly reliable and efficient. The operating range is set using the provided adjustment screws. The 35040028 is also equipped with phase rotation detection feature which helps in detecting and correcting improper phase rotation wiring.

The working principle of the 35040028 is quite simple. It consists of a current transformer which senses the AC current and converts it into a proportional output signal. The output signal is then sent to the relay’s monitoring circuit which compares it against a pre-set value. If the output signal exceeds the pre-set value, the relay will switch the output contacts to activate the contactor and cut off the power supply.

In addition to that, the 35040028 also features a self-resetting function which re-energizes the contacts if the current is within the set range for more than two consecutive cycles. This helps in preventing excessive overloading or resetting the circuit due to a sudden surge in current.

The 35040028 is also capable of providing a reliable trouble-free service with minimal maintenance required. It is also backed by a five-year warranty and can be used in a wide range of industrial and commercial applications where accurate monitoring and control of electric current is required.

In conclusion, the 35040028 is a reliable current monitoring relay with adjustable range and phase rotation detection. It is widely used in various industries for monitoring and controlling electric current, voltage and other parameters. It is easy to install and extremely reliable, making it an ideal choice for any power system installation.
