       RM3-TG30系列电压相序多功能保护器（又称三相电源监视器、相序保护器、相序继电器等）主要用于交流50/60Hz，额定电压500V以下，工业三相220V、380V、440V、460V、500V等电压级别的各种故障检测，对三相输入电源的缺相、逆相(相序)、三相电压不平衡等提供继电保护，产品广泛应用于空压机、电动机、配电箱、水泵、油泵、中央空调机组、电控箱、配电柜、起重机等，如中央空调压缩机保护，各种电梯的电源监视，水泵、油泵防缺相、逆相保护等，是工业设备运行中维护设备工作电压正常的不可缺少的保护产品。本产品符合GB14048.5－2001 EQV IEC60947－1：1999标准。

       RM3-TG30 series voltage phase sequence multifunction protectors (also known as three-phase power monitor, phase sequence protector, phase sequence relay, etc.).To communicate 50/60hz, rated voltage 500V, industrial three-phase 220V, 380V, 440V, 460V, 500V and other voltages.All kinds of fault detection of the three-phase input power supply, such as phase phase, phase sequence, three-phase voltage imbalance, etc., provide relay protection and wide range of products.Apply to air compressor, motor, distribution box, water pump, pump, central air conditioning unit, electric control box, power distribution cabinet, crane, etc.Central air-conditioning 

compressor protection, all kinds of elevator power monitoring, water pump, oil pump anti - phase, inverse phase protection, is the industrial equipment operation maintenance.The indispensable protection product for the normal working voltage of the equipment. This product conforms to GB14048.5-2001 EQV IEC60947-.1:19 99 standard.

产品特点 Product features

◆安装方式：该保护器底座采用导轨式，并设两个M4螺孔结构，直接独立安装或HT35导轨安装（如采用直接安装，需将产品底部两侧附件用力推出）。

◆指示灯：以3个指示灯分别来指示：正常，错相，缺相（电压三相不平衡）。

◆外型尺寸：79mm×23mm×79mm

◆Installation method: this protector base adopts the guide type, and two M4 screw holes are installed, which can be installed directly independently or in HT35 guide rail (for example).With direct installation, the bottom side of the product should be pushed out.

◆Indicator light: the indicators are indicated by five indicators: normal, missing phase (voltage three-phase imbalance), inverse phase, overpressure, and undervoltage.

◆External dimensions: 79mm*23mm*79mm.
