2744-120

产品型号：2744-120 产品名称：2744-120 产品分类：Current Monitors 品牌：Time Mark Corporation（美国时间标记公司） 产品简介：The Model 2744 3-Phase Over Current Monitor is designed to monitor the current level of a three-phase line or to compare the currents of three single-phase lines. If one or more current inputs rises above the trip level after the start delay has expired, the internal relay will de-energize. An adjustable start delay of 5 to 15 seconds will prevent nuisance tripping on start up. The current trip point is adjustable from 1 to 5 amps, and matching current transformers are available to extend the current range of the monitor. The Model 2744 will automatically reset when the current fault is corrected. An external manual reset can be added by installing a normally closed switch between the terminals marked RESET. 技术参数：Contacts: SPDT; Mount: Surface Mount; Trip Restart: Yes; Current Input: 5A; Voltage Range: 120VAC 应用领域：适用于电机过载保护、电流监测、负载状态检测、节能控制、设备状态监控等电流监测场景 产品特点：美国原装进口，品质可靠；DIN导轨安装，方便集成；LED状态指示，直观易读；宽电压范围，适应性强；工业级设计，经久耐用
