제품 상세 설명

LOAD LIMITER is designed to fully protect AC motor against conditions can cause damage.
It can protect the overload mechanical equipment such as Hoist & Crane.
If the motor is overloaded, phase over-current is monitored on the display, alarm goes off and the relay energizes a contactor or breaker to cutoff the power automatically.

  • 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 by memorizing 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.
