product description

Intelligent motor protection is comprehensive motor protection, motor over-current, overload, idling, phase loss, stall, short circuit, overvoltage, undervoltage protection measures to be leakage and three-phase imbalance, the main application control and protection for fans, pumps, motors and other loads.

Protection integrated motor pumps full range of protection technology, micro-processing chip as the core of the arithmetic unit, the operation speed, high reliability, and has a complete communications and analog transmitter output capability. Motor to provide better protection aspects of the comprehensive, reliable, easy to operate, but easy to install and maintain. The scope and sensitivity than the high thermal relay, can effectively avoid the motor burned out, thermal relay action is not the case, the thermal relay is ideal upgrade products.

RC15-40 motor (pump) intelligent protection, for 50HZ.380V phase AC motor circuit, overload, idling, over-voltage Fault of a new protector.

Scope

In everyday use, causing the motor burned main reasons are the following:

◎ contact with a contact due to arc impact wear, resulting in motor phase.

◎ submersible pumps, sewage pump due to water extraction was complete, the cooling water pump in a short time and not get burned.

◎ water pump for a long time do not rust stuck or gravel stuck impeller and burned.

◎ due to internal motor bearing wear caused by stuck stall.

◎ long motor overload burned.

◎ due to overload or under-heating of the motor and cause burn.

These are the main causes of the motor burned, RC15-40 series intelligent protection in modern industry motor burnout, play a significant protective effect, making it easy to bring production units.

More traditional protection switch and wiring

RC15与传统保护开关接线方式的比较
Figure A: external auxiliary devices and more, to increase user costs; auxiliary circuit contact many, many hidden dangers, you need a professional electrician to install or repair.

Figure B: easy to use and easy to understand, no electrician also be installed separately.

Instructions for use

1. Overload current setting

After wiring is complete protection, the overload setting DIP switch to exit, close the gate, the motor is running, the idle setting DIP switch input circuit breakers rated current is automatically saved, LCD normal.
RC15使用说明-1

After Intelligent Pump Protection energized to cycle through the current and voltage information.
2. idling protection settings
After protection wiring is complete, the idle setting DIP switch to exit, close the gate, the motor is running, the idle setting DIP switch inputs, the circuit breaker automatically save the motor operating parameters, slip protection into the liquid crystal display properly.

RC15使用说明-23. Fault Disposal
After the motor failure, automatic circuit-breaker opening, while opening the display and fault conditions.

(1) phase: The intelligent motor protection detects the motor phase, circuit breakers breaking, opening the LCD display, phase and phase information (Figure 3-4).

(2) Overload: higher than the rated motor current, overload, circuit breaker off, opening the LCD display, overload and current information (Figure 3-5).

(3) Brown: The intelligent motor protection detects the motor phase, circuit breakers breaking, opening the LCD display, voltage and voltage information (Figure 3-6).

(4) Overvoltage: The intelligent motor protection detects the motor phase, circuit breakers breaking, opening the LCD display, voltage and phase information (Figure 3-7).

(5) idle: The intelligent motor protection detects the motor phase, circuit breakers breaking, opening the LCD display, voltage and voltage information (Figure 3-8). Idle only RC-15-40S submersible pump intelligent circuit breaker.
RC15使用说明-3

Reset (re-closing): motor failure, intelligent protection after protection action, the first based on the LCD screen to display information, excluding the line, motor and load mechanical failure, press the Set button, reset the Smart Protector, LCD display returns to normal after, try closing it again.

working environment

◎ elevation: the installation site altitude of not more than 2000 meters.

◎ ambient temperature: the upper limit of not more than + 40 ℃, the lower limit of not less than -5 ℃.

◎ atmospheric relative humidity: not more than 70%.

◎ no significant shake and shock vibration.

◎ No explosive medium, the medium does not enough to corrode and damage the insulation of gas and conductive dust.

◎ no rain and snow.
