295-240

产品型号：295-240 产品名称：295-240 产品分类：Special Controls 品牌：Time Mark Corporation（美国时间标记公司） 产品简介：The Model 295 Capacitor Trip Device is used to trip circuit breakers requiring an AC voltage, by using the stored energy in a capacitor. The capacitor is kept at full charge during normal operation by a half-wave silicon rectifier which draws its energy from the power line. When completely discharged, the Model 295 draws approximately 10 amps from the line in the first half cycle, 3 amps the second half cycle and 1 amp from the third. Continuous current required to keep the capacitor charged is less than 5 milliamps. The capacitor holds sufficient charge to trip the breaker for at least 12 seconds after the charging voltage is removed. However, on most fault conditions, some voltage is still present, so the Model 295 is designed so that 65% of normal voltage gives sufficient charge to trip the breaker. A low-energy lamp, connected in parallel with the storage capacitor, gives a visual indication when the voltage charge is 85 volts or more on the 120V version and 170 volts or more on the 240V version. 技术参数：Mount: Surface Mount; Voltage Range: 190-240VAC 应用领域：适用于特殊工业控制需求，包括定制化控制方案、专用监测设备、特殊功能继电器等 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
