The company name derives from intelligent (apparatus). INT is always focused on R&D of electric system intelligent apparatuses.
To meet market requirements, INT grandly launched the following new products: ET45 Series Intelligent Trips, MPD-100 Series Motor Protection Controllers, and Online Monitoring System of Power Equipment, which enriched INT’s product line.

ET45 Series Intelligent Trips

　　ET45 intelligent trips are applicable to DW40/45/48 air circuit breakers and DW conventional circuit breakers, provided with such functions as measurement, protection, alarm, control, input, display, communication and built-in web server (with the external module required). ET45 is used to protect lines and power supply from damage caused by overloading, short circuit, grounding or leakage in the three-phase AC 380v or 660v electric power system. With it, automatic switchover among lines and loads can be realized to have reliability improved in the power supply system, and also the functions including remote signal, remote measure, remote control and remote adjustment can be realized in the power distribution system.

MPD100 Series Motor Protection Controllers

　　MPD100 Motor Protection Controller realizes the protection of motor from overheating, overloading, stall, undercurrent, unbalance, grounding, leakage, under-voltage or over-voltage by controlling the contactor in the control loop of an AC motor. With integrated functions like measurement, protection, alarm, motor operation, display and communication, MPD100 is quite suitable to 50Hz/660V/1A-250A AC motors. It, through the cooperation with a fuse knife-blade switch, can substitute for common-used protectors like the thermal relay, the time relay, the intermediate relay, the transmitter, PLC and the cable. A compact structure makes it easy to be installed to the low-voltage control terminal MCC cabinet or 1/4-modulus drawer cabinets.


Online Monitoring System of Power Equipment

　　MOA online monitoring;
Mechanical characteristic parameter monitoring of high-voltage circuit breakers;
Online monitoring of SF6 gas pressure and moisture content;
Monitoring and diagnostic technique of dissolved gas in transformer oil
