Equipment Protection Ground-Fault Interrupters (30mA)

Ground fault interrupters are an effective means of preventing severe electrical shock.  A GFI device which protects equipment (not people) is allowed to trip as high as 30 mA of current.

Ground faults occur when the electrical current strays outside its normal path.

To protect against electrical shock, Siemens Equipment Ground Fault Interrupters continuously monitor the difference in current between the hot and neutral conductors. If the electricity going to an outlet equals the current coming back from the outlet, the Equipment Ground Fault Interrupter is dormant. If the electricity going to an outlet is greater than 30mA than the current coming back from the outlet, the Equipment Ground Fault Interrupter will open the circuit to stop of flow of electricity.

Features and Benefits

  • Provides protection of equipment from damaging line-to-ground faults currents.

  • De-energizes the circuit for all ungrounded conductors of the circuit.

  • Resists false tripping (shielded to prevent RF interference)

  • Standard 1 inch per pole format with bolt-on design
