IP3753 digital motor protection Introduction IP3753 digital motor protection device (hereinafter referred to as the protector) is mainly used to protect the AC voltage 220V, frequency 50Hz, current 1000A following the various AC motor. Overload, stall, light load imbalance / phase, overvoltage / undervoltage, short-circuit, ground fault protection, and a maximum permissible breaking current protection and parameter measurement, operational control, telecommunications and other functions. Its main use of transformers with separate current input method, must comply with the special or general purpose use with CT module. The protection uses measurement, protection, control-one design, real-time display of measured parameters, fault status, users can easily set parameters, reset operation. In the full realization of protection, measurement and control integration, while RS485 communication network connected with the control center, so as industrial process control provides a scientific and effective field-level protection, monitoring and control unit. IP3753 digital motor protection is the company to meet different customer needs and the development of professional protection, has powerful functions, intuitive display, easy to set up, etc., mainly used in chemical, petrochemical, building materials, metallurgy, municipal, environmental protection, and other industries distribution sites. When the motor rated current is greater than 1A, need special or general purpose external current transformers. The company is the only one in Jiangxi power components manufacturer, the company has a strong R & D production technology, product sales of the first, top quality, direct selling, interested, please contact: 18879987699 QQ: 2880308219 can also visit the company's official website www. hjgroup.org understand the company's products 2. Product Features measurement functions IP3753 digital motor protection with high accuracy (0.5%) to measure voltage, phase current and ground current, current ratio can be arbitrarily set, directly indicate the primary measured current value ; number (0 to 9999 days) also recorded cumulative motor running day and current imbalance rate. Protection features provide overload protection, short circuit, grounding, stall, under current imbalance, phase, undervoltage, overvoltage, and the maximum permissible breaking current protection and other protection functions (optional overload definite time or inverse) . Alarm function with overload protection, stall, undercurrent, unbalance, phase loss, undervoltage, overvoltage and other alarm function; when a fault occurs, the protector blinking alarm type, and shows the fault alarm and countdown ; after the end of the countdown downtime.

Definite time protection time set by the user, based on inverse time overload protection time factor and the slope of the curve is calculated from the specific actions refer to the table or inverse time protection characteristic curve. Current limit alarm function when the motor current exceeds the current limit alarm setpoint, the protector will alarm countdown, after the end of the countdown conduct current limit protection alarm output. The company is the only one in Jiangxi power components manufacturer, the company has a strong R & D production technology, product sales of the first, top quality, direct selling, interested, please contact: 18879987699 QQ: 2880308219 can also visit the company's official website www. hjgroup.org about the company product control function has three relay outputs to meet the motor direct starting, star / delta starter, calls delay from the start, or remotely start and stop, stop, etc. protection, arbitrarily set to call time delay from the start ( 0 to 999.9 seconds), to achieve the motor starter in batches. Communication function (optional, only for -C models) with RS485 interface, MODBUS-RTU communication protocol with RTU, PLC and a variety of computer control configuration software (iFIX, WinCC, Intouch, configuration king, MCGS) achieve network communications, the distributed motor comprehensive protection monitoring system. Transmitter output function (optional, only for -A1 model) selectable settings A, B, C phase current of one phase transmission output DC4 ~ 20mA (factory default 0 ~ 1A corresponds DC4 ~ 20mA). Large dot matrix LCD screen using 128 × 64 dot matrix LCD display measurement results and parameters, clear and intuitive. Event logging functions when the motor is faulty or current limit alarm, the protection will automatically record the fault type and fault values. Protection can record 10 or current limit fault alarm events, the latest in a current limit fault or alarm events stored in the first one, in order recursive backward, appeared once again set a record current limit fault or alarm.
