These Klixon breakers can be placed in between the Bussmann 285 and the Bussmann 187 series in quality and performance. They offer the interrupt capacity that is equal to the Bussmann 187 breakers, but their operating voltage limits are lower, 24 volts instead of 48 V, their terminal studs are 1/4" instead of 5/16" and their waterproof rating is only IP67 (immersion) instead of IP66 (water jets)
