<div class="moz-cite-prefix">I know you said that you would prefer
breakers, but I've used Boltswitch pullout disconnects with class
T fuses on many systems. In the past 15 years, I've only blown 1
class T fuse, and they do offer better circuit protection. Here's
a PDF of some class T rated fused switches that are rated from 200
amp to 1200 amp DC. See the series T models.<br>
