Series C Moulded Case Circuit Breakers
Earth Leakage Circuit Breakers
General Information
Applications
Earth Leakage Moulded Case Breakers offer superior Class 1 ground
fault protection and improved
ground fault coordination capability,
and are listed under UL489 and 1053
as well as CSA C22.2 No. 5 and 144
standards.
Three-Phase, Four-Wire Loads
For three-phase applications with
line-to-neutral loads, select 4-pole
earth leakage breakers and wire the
neutral through the fourth (right) pole.
Earth leakage ground fault protection
differs from other types of systems in
its level of sensitivity. The sensitivity
of traditional devices is limited by the
cumulative error of the residual current sensors and the placement of
the phase and neutral conductors
inside the current sensor.
Typical Earth Leakage Circuit Breaker
July 2007
Earth Leakage breakers and motor
protectors are zero sequence sensing
devices. They are factory supplied
with a single sensor and ground fault
relay built-in. This technique allows
for protection sensitivities down to
the 30 milliampere level.
Earth Leakage breakers and motor
protectors are provided with a full
complement of easy adjustments.
The ground fault pickup setting is
adjustable from 0.03 to 30 amperes
in eight steps, and the ground fault
time delay setting is adjustable from
instantaneous to 2.0 seconds in six
steps. When the pickup is set to 30
mA, the time delay setting defaults
internally to instantaneous only.
Increased selectivity provides for
improved coordination with
upstream and downstream ground
fault devices as well as the flexibility
to adjust for transient currents.
Three-Phase, Three-Wire Loads
For applications with only threephase, three-wire, line-to-line connected loads, select 3-pole earth leakage breakers.
Single-Phase Loads
For single-phase, 3-wire applications,
use a 3-pole earth leakage breaker
and connect all conductors through
the breaker. For single-phase, 2-wire
applications, wire to L1 - L2 or L2 - L3.
General
Do not reverse feed. Do not apply on
400 Hz system. Voltage range: 110 480 Vac.
Standard Features

■
Built-in push-to-trip button for
functional testing.
Trip window indicates red when
the breaker has tripped on a
ground fault.
Form C bell alarm contact➀ for
remote indication when the breaker
has tripped under ground fault condition.
Lockable adjustment seal helps
prevent tampering with settings.
Line and load terminals for bare
cable connections.
Accessories
Optional Factory Installed
Internal Accessories
Earth leakage breakers use the same
internal accessories as standard F-, Jand K-Frame Circuit Breakers. Internal
accessories fit in the right-hand pole
space and are available as factory
modifications only.
Optional External Accessories
Earth Leakage Breakers use the same
external accessories as the standard
F-, J- and K-Frame circuit breakers.
➀ This Bell Alarm contact will not change state when the breaker
has tripped on overload or short circuit condition.
