WavePro low voltage power circuit breakers are available in
various levels of interrupting capacity (IC) and are identified
with a suffix in the model number. WPS indicates "standard
IC," WPH indicates "high IC," WPX indicates "extended IC" and
WPF indicates "integrally fused."
High IC and extended IC breakers are used with larger kVA
substation transformers as well as in parallelling applications.
Fused circuit breakers take the IC rating to 200kA rms
symmetrical for the highest short circuit applications.
Refer to Table 12.1 for the interrupting capacity (IC) of
WavePro breakers at system operating voltages.
WPS — Standard IC WPH — High IC
WPX — Extended IC WPF — Integrally fused (200kAIC)

 Power+ trip unit is not available on WPS-50 (5000A) breaker.
Table 12.3 shows the minimum and maximum fuse ratings allowed for WavePro breakers based on the breaker frame size
and rating plug. Maximum fuse ratings protect the circuit breaker under short circuit conditions with up to 200kA available.
Minimum fuse sizes are established based on UL continuous current tests when the fuse is mounted on the circuit breaker.

* These fuse sizes are also available as "Welder Limiters."
ΠClass L fuses less than 800A are not UL or CSA listed. Use Class J fuses for 600A and below. The maximum fuse rating is the largest fuse that tests show will result in proper perfor-
mance of the breaker and fuse in combination under short-circuit conditions. Only Gould- Shawmut fuses should be used for proper coordination.
 Fuses are mounted in a separate roll-out element (fuses shipped as "XS" material).
Ž Integrally fused 1600A frame breakers (WPF-16) equipped with 2500A fuses can be furnished with rating plugs from 300-1600A. Breakers equipped with 2500A fuses
cannot be modified to accept lower rated fuses. WPF-16 breakers equipped with 2000A and lower fuses cannot be upgraded to 2500A fuses. The maximum trip rating
for a WPF-16 breaker is 1200A when furnished with other than 2500A fuses (see chart for min-max fuse rating for each rating plug value). 2500A fuses preclude the use of
shutters in the breaker cubicle.
