NK Technologies announced the AG-LC Series, a new ground fault sensor that makes it easy to monitor larger circuits. The 2011 NEC requires ground fault protection of the main over-current device feeding marinas and boatyards, where these services often carry up to 800 amps. Most sensor designs do not allow the conductors to pass through a single sensing ring, requiring a separate sensing device such as a zero-sequence current transformer. The AG-LC Series resolves this issue with a large solid-core housing design that provides ample space for multiple conductors to pass easily through one sensing window.
Key applications include:
- 监控大机器：在问题造成损坏之前检测到地球泄漏
- 水处理和交付：保持泵送系统安全和运行
- Generators: Shut down equipment when leakage current exceeds hazardous levels
AG-LC Series highlights include:
- Electromechanical relay output provides both normally open and normally closed contacts
- 兼容大多数自动化和控制系统
- Externally powered – choice of fail-safe or standard operation
- Simple field setpoint adjustment
- Adjustable time delay
- DIN Rail or panel mount
