— Lower system cost with ElfaPlus*

How is this achieved?

Value to panel builders UL489 480/277Vac MCB Example

ElfaPlus technology has redefined the maximum rating limits of MCBs with a complete range of UL 489 branch circuit breakers with current ratings up to 63A. Many players offer MCB lines with a maximum 480/277Vac rating of 20-32A and rely on their larger, more expensive molded-case circuit breaker offerings for higher amperages. ElfaPlus is available up to 40A (480/277Vac) and 63A (120/240Vac), allowing you to use it in place of a MCCB.
