AG Series Ground Fault Relays


AG ground-fault relays detect residual AC leakage in grounded single- and three-phase circuits. Choose a solid-state switch or mechanical relay output, a factory trip point or 5/10/30 mA tri-set model, and a 0.75 in (19.1 mm) maximum wire bundle.

Setpoint range:

AG1: 5–100 mA; AG2: 80–950 mA factory set; AG3: 5/10/30 mA jumper-selectable

Output Ratings:

Solid-state: 1 A at 240 V AC or 0.15 A at 30 V DC; mechanical: 1 A at 120 V AC, 2 A at 30 V DC

Power Consumption:

2.5 VA maximum; solid-state 240 V AC option: 2.9 VA

Output(s):

N.O./N.C. solid-state AC/DC switch, SPDT auto-reset relay, or SPST latching relay

Response Time:

150 ms at 5%, 100 ms at 50%, 50 ms at 500% above setpoint

Isolation Voltage:

Tested to 1500 V AC

Case:

Solid-core; UL94 V-0 flammability-rated housing

Approvals:

UR/cUR and CE, configuration-dependent; see Details


AG1 factory trip points are 005–100 mA; AG2 trip points are 080–950 mA; AG3 uses the TR3 jumper-selectable 5/10/30 mA code. Mechanical NOR1/NCR1 outputs require latching LA; SDT1 requires auto-reset DEN or ENE. Solid-state outputs use FS or NF. The 240 V AC supply is a solid-state option only. Noise-immunity variants add -N. UL Recognition does not apply to solid-state AG2 or solid-state 24U/240 supply configurations; see the catalogue for approval limitations.

Pass all current-carrying conductors of the monitored circuit through the sensing window. Follow the installation sheet for conductor arrangement, grounding and external trip-device wiring. The sensor provides a detection/contact signal; use it as part of a suitable protection system.
