Overview of Families
WBT - Feed Thru Tap Box with Horizontal Bus Breaker
Feed thru tap box and breaker module (type WBT) offers
the ability to pull conductors in and out of the enclosure for
rise cable or loop feed applications as well as a main breaker
device utilizing an incoming and out-going thru bus connections
(including incoming lugs). This patented design allows the user to
utilize the WBT family to connect to Siemens Sentron Busway.
Features include:
n Incoming and Outgoing Power Mod thru bus
n Standard compression lug capability
n 65K AIC standard, 100K AIC available for all models
n Broad ampacity ratings up to 1200 Amps
n DAS blue light models available in 1200A

n 200-1200A breaker rating
n 1200-2400A feed-thru rating
n 1200A horizontal bus rating
n UL Standard #67
n UL file #E27100
n AIC rating (65K and 100K)
n Voltage:
– Three Phase 240V AC max
n NEMA 3R rated
Restrictions for WBT Feed Thru breaker tapbox units:
Type WBT feed thru breaker tap boxes cannot be used as service equipment. The feed thru conductors must
have upstream circuit protection. For feed thru conductor ratings up to 2,000 amps, Siemens Sentron or VL circuit
breakers can be used. For feed thru conductor ratings over 2,000 amps but up to 2,400 amps, use Class L fuses.
Please note that Siemens type WL circuit breakers CANNOT be used as the direct upstream main for these WBT
feed thru breaker tap boxes.
BFT - Main Feed Thru
Main feed thru (type BFT) breaker modules has the ability to
isolate power to side-mounted modules just like any other
Power Mod main breaker module, but also contains feed-through
lugs that can be used to supply and isolate power vertically to
downstream group metering line ups.
Features include:
n Incoming and Outgoing Power Mod thru bus
n Standard compression lug capability
n 65K AIC standard, 100K AIC available for all models
n Main breaker with broad ampacity ratings from
1200A to 2000A
n DAS blue light models available in amperages of 1400-1600A
n For 1200A DAS you must use a 1400A DAS module and have
the trip setting dialed down to 1200A in the field.
WS – Standard Switch Mains
Standard switch modules (type WS) are designed for flexibility,
space savings, and durability.
Features include:
n Standard compression lug capability
n Invertibility: 400-800 Amp devices can be rotated to accommodate
the desired incoming feed direction
n 750 kcmil AL wire options for most models
n 100K AIC standard for all models
n Class T fuse provisions
n Broad ampacity ratings up to 1200 Amps
