SE-502接地故障接地连续性检测仪可提供A类GFCI跳闸电平和跳闸时间,用于保护操作人员的安全。该检测仪最低可检测到5 mA的接地故障电流,检测仪内部的中性点接地电阻器将最大接地故障电流限定为100 mA。SE-502适用于通电系统和未通电系统,可持续监测中性点连续性,检测负载端接地中性点,还可执行接地校验。这些功能使得SE-502成为120/208 V便携式发电机和伴热设备的理想之选。
SE-502接地故障接地连续性检测仪在库存部件用完后将不再供应。库存用完后,我们并无提供直接替代产品的计划。请联系您的Littelfuse代表讨论替代解决方案。
- Sensitive 5 mA groundfault detection
- Internal neutralgrounding resistor
- Neutral-to-ground connection monitoring
- On- and off-line monitoring
- 输出触点
- Can be used with an appropriate breaker to provide Class A GFCI people protection
- Limits maximum ground-fault current to 100 mA, creates a safer system and eliminates arc-flash ground-fault hazards
- Can detect a hazardous ungrounded condition and trip or alarm
- Can detect a ground fault when the system is energized or de-energized
- Two Form C output contacts for alarming or tripping purposes
