Rated 2.5 A continuous and Class 10 trip, it fits motor-starting applications that need a short delay, but the transformer-protection designation is the key differentiator: the breaker tolerates the magnetizing inrush of a transformer primary, so you don't oversize the branch. Breaking capacity hits 100 kA at 240 V, 400 V, and 500 V AC (–), dropping to 8 kA at 690 V AC — enough for most industrial panels.
Zero clearance needed at the back or sides — you can butt multiple breakers side by side. Screw terminals on both main and auxiliary/control circuits accept solid or stranded wire: 2x (1... 2.5 mm²) and 2x (2.5... 6 mm²) for both. AWG equivalent is 2x (14... 10) for the main contacts. Any mounting position is allowed.
Lifecycle status is current production — this is an active catalog item, not a phase-out. Shock resistance is 25 g for 11 ms. RoHS compliance date is 01.05.2012. Surge voltage resistance is 6 000 V. Power loss at AC in hot operating state is 7.25 W total, or 2.4 W per pole.
