It combines a Class 10 trip curve with phase failure detection, so it clears a locked-rotor condition before the motor winding exceeds its thermal limit while also catching a lost phase that would single-phase a three-phase motor. The 45 mm width and 75 mm depth leave room alongside contactors in a standard motor starter stack.
Integration notes
Screw-type terminals on the main current circuit accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) solid or stranded wire. Terminal screws are M3 for the main contacts. No special tooling needed beyond a standard screwdriver. Clearance requirements: 20 mm upwards and downwards, 9 mm at the sides, zero forwards or backwards. That's tight enough to pack multiple units side-by-side in a multi-motor panel without oversized gutters.
