Technical Parameters
(1) Protection functions: Phase protection, three-phase unbalance protection, and overload protection.
1. Phase-failure protection: When any phase of the three-phase power supply of the motor lacks a phase or the internal phase of the motor is broken, the action delay time of the protector is ≤ 1S.
2. Three-phase unbalance protection: When the phase difference of any two-phase working current in the three-phase power supply of the motor exceeds (50±10)%, the delay time of the protector operation is ≤1S.
3. Overload protection: When the operating current of the motor reaches 1.2 times to 6 times of the rated value, the action delay time of the protector is 80S ~ 10S (inverse time characteristic).
the output interface reset mode: control circuit power reset; reset time: (60 ± 10) S.
work methods: continuous work style.
applicable voltage range: AC24V ~ 380V/45 ~ 60Hz.
Protector specification selection
1. The user should select the corresponding motor protector according to the rated operating current of the motor to be protected; in a special case, the large-size protector can be applied to the low power motor by increasing the number of power lines passing through the protector's conductor hole. Protection, small size protectors can be applied to the protection of high-power motors by installing the secondary side of current transformers.
2. For motors with rated operating current less than 2 A, use 2 to 5A protectors by increasing the number of turns of the power cables passing through the conductor holes of the protector. Consider that the sampling current of the protector can be ensured when the motor is unloaded. Less than 3A.
