It provides coordinated protection against overload, short circuit, and phase loss for three-phase motors up to 690 V rated voltage.
The 45 mm width and 75 mm depth keep it compact for crowded enclosures. Clearance: 20 mm above and below, 9 mm to the side, zero forward or backward — no extra breathing space needed. Screw-type terminals on the main current circuit accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire. M3 terminal screws for the main contacts.
