The MicroLogic 4.1 electronic trip unit provides adjustable thermal-magnetic curves (not just fixed thermal), which gives better coordination with downstream loads than a thermal-magnetic-only breaker. The earth-leakage sensitivity is selectable from 30 mA to 5 A, class A or AC — 30 mA class A is the standard for personnel protection in most IEC markets; higher settings are for equipment protection or to avoid nuisance tripping on leakage-heavy loads.
This is a panel-mount distribution breaker for commercial and industrial switchboards. It mounts on a backplate, accepts front-connect compression lugs or busbars, and occupies 9 module pitches (108 mm wide). The IP40 front face suits dry indoor enclosures; the IK07 impact rating means it withstands accidental tool strikes during panel wiring.
