Trip Class 10 means it clears a locked-rotor condition within 10 seconds at the set overload current — fast enough for most standard induction motor starts without nuisance tripping. Breaking capacity is 30 kA at 400 V AC, with higher values at lower voltages (100 kA at 240 V) and lower at 500 V (6 kA) and 690 V (3 kA).
Dimensions: 149 mm depth, 55 mm width, 140 mm height. The 55 mm width is three 18 mm module spaces — standard for a motor-protective device in a distribution board. Mounting position is any; clearance above and below is 50 mm, 10 mm at the sides.
