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, ANSI/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 Re-mapping procedure is done by Pressing
simultaneously the "Right", "Left", and "Up" Arrow all at the
same time (should be able to do with one hand). "BIM OK"
will be flashing in the upper left hand corner of the LCD
when this is performed. Another Method is to use Modbus
Command 107 "Upload BIM" Either procedure requires the
trip unit to be mounted to the breaker and control power be
provided to the trip unit from permanently connected
control power or a portable power supply via the front port.
Front 24VDC Power is provided by Either the GTUTK20 Test
Kit or the Portable Battery Pack, TVPBP and TVPBPACC.
All Universal Trip units have the following format G1X00-----
RXXXX. The middle 5 digits describe the trip unit protection
options and features.
