Current detection type compatible with 0.1kW to 0.4kW.
- It detects overcurrent during motor overload and stops the motor. Additionally, there are relay contacts for signaling (a contact/b contact), so it is also possible to protect the motor by controlling (circuit interruption) to stop the motor using these signal contacts.
- Unlike breakers or thermal devices, it can cut off the motor power based on a user-defined current value, allowing for instant protection of the reduction gear and mechanical equipment.
- Various settings for detection current, load timer, and start cancel timer are possible (factory default settings).
- Detection current: The set current value for motor overload protection.
- Load timer: The time from exceeding the detection current to cutting off the motor power.
- Start cancel timer: The time to ignore the inrush current when starting the motor.
*Note: It cannot be driven by an inverter. If driven by an inverter, high-frequency voltage will be applied from the inverter output to the current relay board, causing damage to the control power supply section of the board.
