AG Series Ground Fault Sensors help protect people, products, and processes from damage by ground fault conditions by monitoring all current-carrying conductors in grounded single- and three-phase delta or wye systems.
“Zero Sum” Operating Principle: In threephase delta and wye systems, under normal conditions current in the ‘hot’ leg of a two-wire load is equal in magnitude but opposite in sign to the current in the neutral leg. As a result, the electromagnetic fields surrounding these two conductors cancel, producing a “zero sum current.” As soon as current leaks to ground (fault condition) the two currents become imbalanced and a net magnetic field results. AG Series sensors monitor this field and trip alarm contacts when the leakage rises above setpoint. |

Personnel Protection (typically 5mA)
- Detects sensitive ground fault conditions,
which may be injurious to personnel and processes.
- Functions as sensor and alarm trigger when
part of an overall ground fault protection system.
|
Equipment Protection (typically 10mA or 30mA)
For applications where personal protection is not the primary concern, higher setpoint capability helps eliminate nuiscance tripping while still providing adequate ground fault detection to protect machine electronics. |
Regulatory
Meets requirements as stipulated by governmental and industrial regulatory groups for ground fault sensing. |
| |
| AG Series with Solid-state Outputs offer the benefit of reliable, long-lasting solidstate switches. Sold-state design provides unlimited switch operating life, superior resistance to shock and vibration, zero offstate leakage, high switch speeds and high input-output isolation. Available in solidcore case with screw terminals. |
