Breaking capacity hits 242 kA at 240 V AC, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 3.7 kA at 690 V — the 690 V figure is the limiting case for high-voltage low-current applications.
Current rating and thermal performance
Maximum power loss is 25.5 W, which matters for enclosure heat load calculations when ganging multiple breakers.
The 140 mm width means it occupies four standard 35 mm DIN-rail module spaces (36 mm per pole plus inter-pole gaps). Bolts onto the back panel or mounts on a DIN rail adapter plate — verify the adapter for this frame size.
