The motor protector is all-round intelligent motor protector which adopts the advanced electronic circuit and patent technology. It's a notch above the technical level compared with the domestic similar products using common circuit. This product can protect symmetrical fault (such as overload, locked-rotor, leakage, etc.) and asymmetric fault, such as unbalanced three-phase, phase protection function, used with AC contactor, provide the fast, reliable protection of motor. It is mainly used in metallurgical, chemical, textile, building materials, electricity, communications and other industrial three-phase motor and three-phase power supply system. It is convenient to use the machine to output 4-20mA and connect with DCS. It possesses strong anti-interference, stable and reliable in work, high measuring accuracy, Simple protection parameter setting and convenient installation, attractive in price and quality, can satisfy the requirements of different users.
Main features:
1、The main loop through the protector current sensor current sampling mode.
2、The current value is shown on the digital display,the fault is shown by the indicator light.
3、Overcurrent protection against time limit.
4、Rated current and start delay time can be set separately.
5、Compact structure, can be combined into one, can also separate installation.
6、The output of 4-20mA standard current signal can be directly connected with the industrial secondary instrument or computer system.
7、A multi-purpose machine can replace ammeter, thermal relay, current transformer, time relay and leakage.
8、With the RS485 interface, it can carry out information transfer, and a stage machine (PC) can connect to 256 protector, and can set the parameters of each motor and stop operation to facilitate automatic management.
Protection function:
Overcurrent, block, three-phase current imbalance, phase fault, leakage and other fault protection.
Setting function:
The rated current value and the motor start delay time can be set.
Display function:
The actual current value is displayed when running state, and all kinds of failure indicators are displayed when the state is protected.
Remote function:
The output interface of the 4-20mAcurrent signal is directly connected with the DCS system.
Main technical parameters:
