JR29（T）系列热继电器
产品简介
详细信息
| 一、用途及适用范围 INTRODUCTION AND APPLICATIONS T系列热继电器适用于交流50HZ或60HZ,电压至660V,电流至500A的电力线路中。一般用作三相感应电动机的过载与断相保护，常与B系列交流接触器配合组成电磁起动器。本产品是引进德国ABB公司制造技术的产品。 注：T16为手动复位，其他为手动和自动复位。具体见《产品使用说明书》 T series thermal overload relay is mainly suitable for A.C.electric power system with voltage up to 660V,current up to 500A,50-60HZ.It is generally used for the protection of overload and phase-tacking in circuits with three-phasse induce motors and is offen made up electromagnetic starters with B series A.C.contactors. Note:T16 is manually reset aucomatic to the other.AS shown on 《The operating introduction》 二、动作特性：三相负载平衡时的动作时间 MOTION CHARACTERISTIC:THREE-PHASE BALANCE MOTION TIME |
