At 45 mm wide and 90 mm tall, it occupies a single standard modular slot, leaving room alongside contactors and overload relays in a dense panel layout.
At 690 V it still clears 2 kA, enough for many 690 V motor circuits in mining or marine gear. That prevents single-phasing damage on a motor that would otherwise try to run on two phases and burn up the winding. The gL/gG fuse backup ratings let you coordinate with upstream fuses: 80 A at 240 V, 63 A at 400 V, 40 A at 500 V and 690 V. That tells your panel designer what fuse size to spec ahead of this breaker to keep selective coordination.
Mounting position is any — vertical, horizontal, upside down — no derating needed for orientation. Screw-type terminals on the main circuit accept 2× (0.5 to 1.5 mm²) or 2× (0.75 to 2.5 mm²) solid or stranded copper. Terminal screws are M3. Clearance around the unit: 20 mm above and below, 9 mm to the side, zero in front or back — tight panel spacing works.
Environmental range and storage
Operates from -20 °C to +60 °C, with temperature compensation active across that entire span so the thermal trip curve stays accurate. Rated voltage range covers 20 V to 690 V, so it works on control voltages as low as 24 VAC/DC as well as standard 400 V and 690 V power circuits.
