This overload limiter is a fixed protection device specially designed to protect the mechanical overload of the three-phase motor. When the external mechanical overload or impact load, the motor current will increase, then the current transformer (CT) detects the secondary current and compare it with the set value, when the set value is exceeded, it is judged to be overloaded. At this time, the overload of the relay is confirmed to immediately cut off the power supply. At the same time, the alarm buzzer sounds and the warning light flashes to remind the operator that the machine is overloaded. It is a highly reliable overload protection device.
Features:
●Fine setting time and current are available by Microcomputer built-in it
●Running current to motor is displayed itself. Thus, setting current is easily.done without extra current meter.
● It is automatically reset if hoist or crane is descended during the reset time bymemorizing ascending time.
●Wiring and installing are very simple by using of external current transformer(CT).
In case of being used for creep hoist.the device displays each trip signal and current setting.
● The device can be used as the over current relay for protecting AC motor
