Section 3. EntelliGuard TU Trip Unit System
Universal Spare Trip Unit
EntelliGuard G circuit breakers will accept a
Universal Spare Trip Unit. This unique trip unit
may be used in any EntelliGuard G circuit breaker
regardless of frame size, sensor size, short circuit
rating or whether the circuit breaker is listed under
UL 489, UL 1066 or IEC 947 standards. Should any
circuit breaker's trip unit fail to operate for any
reason, this one universal trip unit may be used as
a replacement.
Once an EntelliGuard TU trip unit, including the
Universal Spare Trip Unit, is associated with a specific
EntelliGuard G circuit breaker, it may only be used
with that specific circuit breaker. If swapping
between EntelliGuard G circuit breakers is required,
a trip unit may only be swapped between circuit
breakers with equal sensor ratings, short circuit
ratings and standard listing. Before the circuit breaker
may be used with a swapped or new trip unit, the
trip unit must be mapped to the circuit breaker.
The mapping procedure is described in the trip unit
instruction book and requires that control power
be provided to the trip unit from permanently
connected control power or a portable power supply

and communication connection.
Universal Trip Units may be ordered with a limited
set of options. It is suggested that they be ordered
with the widest range of options used within a
facility, as any unnecessary functions can always
be disabled or turned off (except for Ground Fault)
during set up by the user. The user-selected options
for Universal Trip Unit are listed in Table 3.12.
