ALBRIGHT接触器DC88系列介绍
DC88
MOTOR REVERSING
The DC88 motor reversing type of contactor has been designed for direct current loads, particularly motors as used on electric vehicles such as industrial trucks. The DC88 is a monoblock construction, resulting in a compact design which is compatible with modern electronic control systems. Developed for both interrupted and uninterrupted loads, the DC88 is suitable for switching Resistive, Capacitive and Inductive loads.
The main contact circuit, designed for motor reversing, has a built in failsafe, so that if both coils are energised simultaneously the contact arrangement is open circuit. The DC88 has double breaking main contacts with silver alloy contact tips, which are weld resistant, hard wearing and have excellent conductivity. The DC88 M8 main stud terminals can be configured in a variety of ways in order to suit the application. Coil connections are by means of 6.3mm spades and mounting is via the supplied bracket and can be horizontal or vertical, when vertical the M8 contact studs should point upwards. If the requirement is for downwards orientation we can adjust the contactor to compensate for this.

电机反转
DC88 电机换向型接触器专为直流负载而设计，特别是用于工业卡车等电动车辆的电机。 DC88 采用一体式结构，设计紧凑，可与现代电子控制系统兼容。 DC88 专为间断和不间断负载而开发，适用于切换电阻、电容和电感负载。
专为电机换向而设计的主触点电路具有内置故障保护功能，因此如果两个线圈同时通电，则触点布置为开路。 DC88双断主触头采用银合金触头，耐焊、耐磨、导电性好。 DC88 M8 主螺柱端子可以以多种方式配置以满足应用。 线圈连接采用 6.3mm 铲形，通过随附的支架进行安装，可以水平或垂直，垂直时 M8 接触螺柱应朝上。 如果要求向下定位，我们可以调整接触器以对此进行补偿。
