Breaker Weights and Fuse Ratings
Weights of WavePro™ drawout low voltage power circuit breakers and associated drawout fuse carriages (fuse roll-out ele-
ment) are shown in Table 32.1.
Table 32.1 WavePro breaker and fuse roll-out weights
Table 32.2 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.
Table 32.2 Allowable current limiting fuse sizes for WavePro low voltage power circuit breakers (600VAC max., 50/60 Hz)
* These fuse sizes are also available as “Welder Limiters.”
➀
Class 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 performance of the breaker and fuse in combination under short-circuit conditions. Only Ferraz-Shawmut fuses should be used
for proper coordination.
➁
Fuses are mounted in a separate roll-out element (fuses shipped as “XS” material).
➂
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.
