Three-Phase Four-Wire Current-Limiting Over/under Voltage Protector｜phase Loss, Three-Phase Imbalance, Neutral Line Break, Phase Sequence Protector｜jgxl-63

Introduction

  The JGXL-63S three-phase four-wire current-limiting overvoltage and underVoltage Protector is mainly used in power systems with AC 50Hz (60Hz), a rated working voltage of 220/380V, a main body rated current from 2A to 63A, an adjustable working current of the intelligent controller from 2A to 63A, and a control power from .5KW to 20KW, to make, carry and break currents or voltages under normal conditions (including specified overload conditions), and can also make, carry for a certain period of time and break currents or voltages under specified abnormal conditions (such as short circuit, undervoltage, etc.).

   The three-phase four-wire current-limiting overvoltage and underVoltage Protector adopts a modular product structure, featuring advantages such as compact size, high reliability, and ease of operation. The main functions of the product include: overvoltage, undervoltage, phase loss, neutral line break, overcurrent, instantaneous short circuit, three-phase imbalance, undercurrent, phase sequence, RS485 communication, one-key restore to factory settings, etc. It is widely used in power distribution and motor protection control systems in fields such as telecommunications, metallurgy, coal mining, steel, petrochemicals, ports, ships, railways, hospitals, and intelligent buildings.
