Connections

Applications

■ Personnel Protection (typically 5mA) Senses low fault currents and alarms to shut power before injury occurs.

■ Equipment Protection (typically 30mA) When personal protection is not an issue, select a higher setpoint to protect equipment or product.

■ Regulatory Approval

Meet requirements by industry groups and governments for Ground Fault Protection.

Features

■ Broad Range of Options to Match Application Needs:

— Choice of NO/NC solid-state switch and mechanical relay outputs.

— Normally energized or normally de-energized contacts.

— Latching outputs for controlling contactors; auto-reset option for control of shunt trip breakers.

— Noise-immune option for use in EMI/RFI sensitive environments.

■ Setpoint Options Maximize Ease-of-Use:

— Field-selectable 5mA, 10mA or 30mA setpoints (AG3 “Tri-set” model only) makes user-adjustable setpoint fast and convenient.

— Single, factory-adjusted setpoint can be fixed from 5mA to 950mA when ordering.

■ Compatible with Standard Equipment

— Applicable on most 1Φ and 3Φ systems.

— Ideal for use with shunt trip breakers or contactors.

— Magnetically isolated from monitored circuit and control power.

■ Agency Approved

UL, CUL and CE acceptance worldwide.
