ZJR7 series motor soft starters are suitable for three-phase AC squirrel-cage asynchronous motors with AC 220-480V/50(60)Hz and rated current 1260A and below. This soft starter is a device type and needs to be equipped with a circuit breaker (short circuit protection) and AC contact (for bypass) in the cabinet, and cooperate with the switch to form a motor control circuit.
ZJR7 series products do not need to install thermal relays,and have complete electricalcircuits during motor starting and operation.
sMotor protection function; closed-loop control is adopted,which greatly improves the smoothness of soft torque starting and soft torque stopping of the motor.
performance and reliability,a bypass contactor is used during operation,and the operatingpower consumption is close to zero,which not only improves reliability but also reduces Smaller overall dimensions.
Main Features
1. With two models of external bypass and internal bypass, it is convenient for customers to choose.
2. Main terminal connecting line is fixed directly by screws, which is safe and reliable.
3. The control line alone power supply is more stable, can make the main power supply range covers 220-480V without changing the machine.
4. LCD display, standard Chinese and English options, more convenient to use, can also be customized according to customer requirements of other language types.
5. Three groups motor parameters can be switched, more convenient to use.
6. With PTC temperature sensor interface, motor protection is more comprehensive.
7. Equipped with RS485 communication interface as standard, it is more convenient for group network control.
8. 10 sets fault records, Easier to find problem .
