The ABB XT4HU3100AFF000XXX is a molded case circuit breaker (MCCB) from the XT4H 250 TMF series, rated for 20 A continuous current across a 3-phase, 4-pole configuration. That 20 A rating governs the maximum load it can protect in normal operation — sized for a branch circuit feeding a motor, a panel, or a distribution subfeed. The 4-pole design (three phases plus neutral) suits it for systems where the neutral needs overcurrent protection or where you're switching a 3-phase + N supply.
