380 Volt Overcurrent Current Balance Relay Integrative Structure For Blowers

120 Volt Overcurrent Current Balance Relay Integrative Structure For Blowers

Protection function Phase protection, three-phase unbalance protection, overload protection.
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.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. Overload protectionWhen 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.
