LT4706M7A Schneider Relay

LT4706M7A Schneider RelayThe emergence of this technology can meet more comprehensive protection needs for machinery and equipment.
The action characteristics of electronic overcurrent relays are time limited curves: the basic functions are current threshold setting and time setting.
This type of protective relay * is used for mechanical protection of machines, especially for high load torque, large inertia, and normal operation, and has significant potential
In the event of motor stalling. It is also suitable for motor protection under conditions of long starting time or frequent starting.
In addition, the LR97D product also integrates two fixed action time protection functions: one is rotor lock protection that operates within 0.5s, and the other is
Phase loss protection for actions taken within 3 seconds.
LR97D and LT47 can provide mechanical impact protection to replace traditional safety pin protection methods; Under this protection method, it is possible to
Setting the O-time knob to the minimum value ensures overload tripping within 0.3 seconds.

Technical Features
The Schneider sensor industry is at a critical stage of development from traditional to new sensors, reflecting the overall trend of miniaturization, multifunctionality, digitization, intelligence, systematization, and networking of new sensors. Sensor technology has undergone years of development, and its development can be roughly divided into three generations:
*Dai is a structural sensor that utilizes changes in structural parameters to sense and convert signals.
The second generation is a solid-state sensor developed in the 1970s, which is composed of solid components such as semiconductors, dielectrics, and magnetic materials, and is made using certain properties of the materials. For example, by utilizing the thermoelectric effect, Hall effect, and photosensitive effect, thermocouple sensors, Hall sensors, and photosensitive sensors are respectively made.
The third generation of sensors is a newly developed intelligent sensor that combines microcomputer technology with detection technology, giving the sensor a certain degree of artificial intelligence.
