LINETRAXX® RCMS490-L
- 通过定期检查来取代绝缘测试。组合断路器用于MRCD应用。
- 可以通过选择每个通道的测量电流互感器进行交流、脉动或交流/直流敏感测量
- RCMS490的设备版本每个通道带1个报警接触器
- 谐波、DC、THF的分析
- 对人员保护、防止火灾和设备保护来调整频率值
RCMS系统包括一个或者多个RCMS460-D/-L或RCMS490-D/-L型剩余电流监视仪，它们可以通过相应的测量电流互感器检测和评估接地系统的故障、剩余和工作电流。被监视系统的最大电压取决于测量系统中使用的相关总线排系统的测量电流互感器的标称绝缘电压，取决于穿过互感器的电缆或导体。W...AB系列测量电流互感器应用于交直流剩余电流（符合 IEC/TR 60755：B型的要求）。6个W...AB系列测量电流互感器需要1台AN420或AN110专用电源。W（闭合）、WR（长方形）、WS（开合）和WF（柔性）系列测量电流互感器用于交流和脉动电流（符合IEC/TR 60755: A型）。
各种系列的测量电流互感器的任意组合可以被连接到测量通道中。每个RCMS460-D/-L和RCMS490-D/-L可以连接12个测量通道。通过BMS总线(带BMS协议的RS-485接口)，最多可以连接90台剩余电流监视仪，因此可以监视高达1080个测量通道（子回路）。
如果设备被用于保护人身安全、防火或设备保护，可以按照要求设置频率相应。可分析测量电流的谐波。
