产品型号：274-5-120-A 产品名称：274-5-120-A 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 274 3-Phase Current Monitor is designed to monitor all legs of a 3-phase line, and can also be used to monitor three individual single-phase lines. The output relay will energize on an over-current condition on any one of the 3 monitored lines. Two indicator lamps are provided to show when an over-current condition exists and when the output relay is tripped. An adjustable trip delay of 0.2 to 20 seconds is provided to reduce nuisance tripping. Matching current transformers are available to extend the range of the device to most any range up to 1,000 amps. The Model 274 is offered in either manual or automatic reset models. An external power supply of 24, 120 or 230 VAC powers the device. 技术参数：Automatic Reset: Yes; Contacts: SPDT; Mount: Surface Mount; Trip Delay: 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
