Description
Providing exceptional short-circuit protection, this 3-pole 20A current-limiting MCCB restricts let-through energy to defend sensitive equipment. The thermal-magnetic trip unit delivers reliable fault response. Unlike bolt-on models, this unit-mount breaker features line and load lugs for flexible installation in enclosures, switchboards, and motor control centers. It serves as a robust feed-thru solution.Specifications
