Current and Voltage Sensors
Introduction

EGF Series CurrentWatch
Ground Fault Sensors
EGFL Series CurrentWatch
Ground Fault Sensors
Page V8-T7-33
Overview
Current sensing for DC loads up to 300A
with analog outputs.
Applications
Battery banks—monitors load current,
monitors charging current and verifies
operation
Transportation—measures traction power
or auxiliary loads
Electric heating elements—monitors heater
loads with a faster response time than
temperature sensors
Product Features
Jumper-selectable ranges—reduces
inventory and eliminates zero or span pots
Isolation—output is magnetically isolated
from the input for safety, also eliminating
insertion loss (voltage drop)
Internal power regulation—cuts installation
costs and works well, even with
unregulated power
Split core design and built-in mounting
brackets—makes installation quick and
easy
Current Range
0–400A
Approvals
UL Listed (Pending)
CE
Page V8-T7-37
Overview
Ground fault sensors with solid-state or
mechanical relay outputs.
Applications
Personnel protection (typically 5 mA)—
detects sensitive ground fault conditions,
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
Product Features
Broad range of options to meet application
needs—NO or NC, 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
Current Range
Fixed or adjustable 5/10/30 mA trip
Approvals
UL Recognized
