適用范圍 Applicable scope

       K8AK-PM2系列電壓相序多功能保護器（又稱三相電源監視器、相序保護器、相序繼電器等）主要用于交流50/60Hz，額定電壓500V以下，工業三相220V、380V、440V、460V、500V等電壓級別的各種故障檢測，對三相輸入電源的缺相、逆相(相序)、三相電壓不平衡等提供繼電保護，產品廣泛應用于空壓機、電動機、配電箱、水泵、油泵、中央空調機組、電控箱、配電柜、起重機等，如中央空調壓縮機保護，各種電梯的電源監視，水泵、油泵防缺相、逆相保護等，是工業設備運行中維護設備工作電壓正常的不可缺少的保護產品。本產品符合GB14048.5－2001 EQV IEC60947－1：1999標準。

       K8AK-PM2 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.

產品特點 Product features

◆安裝方式：該保護器底座采用導軌式，并設兩個M4螺孔結構，直接獨立安裝或HT35導軌安裝（如采用直接安裝，需將產品底部兩側附件用力推出）。

◆指示燈：以3個指示燈分別來指示：正常，錯相，缺相（電壓三相不平衡）。

◆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.
