03/23/2016已淘汰。 PGR-6130电子过载继电器可为交流电压达1,000伏的小型三相电机提供保护。集成型CT可用于电流达90安的电路，而外部CT则可用于电流大于90安的电路。保护功能包括：过载、过热、相位不平衡、相位缺失和相序。
- 无需配备CT
- Adjustable trip settings
- 输出触点
- Remote indication
- 过载
- Phase loss/Phase sequence
- Unbalance (current)
- PTC overtemperature
- No current transformers required for currents up to 91 A, simplifies installation and reduces cost
- Adjustable overload trip class setting from 5 to 35 to match motor characteristics
- Allows remote cause-of-trip indication and reset
- Allows remote cause-of-trip indication and reset
- 延长电机使用寿命，避免故障和火灾
- Detects unhealthy supply conditions
- 避免因不平衡相造成的过热
- Detect high ambient or blocked ventilation and single phasing; prevents shaft/pump damage
