The thermal-magnetic trip unit responds to overloads and short circuits; magnetic tripping occurs between 3 and 5 times the rated current, so it clears fast on high-impedance faults without nuisance trips on moderate inrush from lighting or resistive loads.
The toggle actuator provides local ON/OFF indication. Terminals accept 1 to 35 mm² rigid wire; strip 14 mm and tighten to 3.5 N.m. The 78.5 mm depth leaves clearance in shallow enclosures, though the 85 mm height may crowd a 4-row cabinet if busbar routing is tight.
Rated breaking capacity is 6000 A Icn at 230 V AC 50/60 Hz conforming to EN/IEC 60898-1.
