Rated 2.5 A at 400 V with a CLASS 10 trip class, it gives you a 10-second maximum trip time at 7.2× rated current, which is the standard for protecting motor and transformer circuits against sustained overloads. Ground fault detection is not included, so if you need that, you pair this with a separate ground-fault relay or use a different variant.
Mounting and integration — panel fit
Depth is 96 mm, height 97 mm. Zero clearance needed at the sides or rear, so you can pack modules tight. Mounting position is any, which helps in cramped enclosures where you have to orient the rail vertically. Terminals on the main current circuit are screw-type, accepting solid or stranded conductors from 1 to 6 mm² (2x 1...2.5 mm² and 2x 2.5...6 mm² per terminal). AWG equivalents are 14 to 10 for the main contacts.
Environmental and electrical ratings — what they mean for the panel
Shock resistance is 25g for 11 ms — fine for normal industrial vibration, but if the breaker is mounted directly on a vibrating machine (crusher, mill), you may want additional damping. Surge voltage resistance is 6,000 V. Power loss in hot operating state is 7.25 W total, 2.4 W per pole. Mechanical endurance of main contacts is 100,000 cycles typical.
