The CurrentWatch EGF Series from

Eaton’s electrical business is a family

of ground fault (earth leakage) sensors.

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.

The EGF Series is available with

either solid-state or mechanical relay

outputs.

Product Features

■ Broad Range of Options to Meet Application Needs — N.O. or N.C., solid-

state or mechanical relays, normally energized or normally de-energized

contacts

■ Setpoint Options Maximize Ease-of-Use and Application Flexibility — Field

selectable 5, 10 or 30 mA setpoints on the EGF “Tri-set” models make user

adjustments fast, sure and convenient

■ Compatible with Standard Equipment — Application on single- and three-

phases systems, ideal for use with shunt trip breakers, and magnetically

isolated from monitored circuit and control power

The EGF Series with solid-state out-

puts offers the beneﬁt of reliable,

long-lasting solid-state switches.

Solid-state design provides unlim-

ited switch operating life, superior

resistance to shock and vibration,

zero off-state leakage, high switch

speeds and high input-output isola-

tion. Solid-state outputs have solid-

core housings with screw terminals.

■ Agency Approved — UL and CE Certiﬁed, accepted worldwide

The EGF Series with mechanical

relay outputs are available in solid-

core housings with a choice of N.O. or

N.C. SPST latching relays and a SPDT

Form C relay with auto-reset. All

mechanical models can be ordered

with a ﬁxed setpoint or with a “tri-

set” option, which provides three

factory-set, ﬁeld-adjustable setpoints.

Typical Applications

■ Personnel Protection (Typically 5 mA) — Detects sensitive ground fault con-

ditions, which could cause injury to people, and functions as a sensor and

alarm trigger when applied as an input to an overall ground fault protection

system

■ Equipment Protection (Typically 10 or 30 mA) — For applications where

personnel protection is not the primary concern, higher setpoint capability

helps eliminate nuisance 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

Approvals

■ UL Recognized

”Zero Sum” Operating Principle

In three-phase 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 a 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. The CurrentWatch EGF Series sensors monitor this ﬁeld

and trips the contacts when the leakage rises above the setpoint.
