The 4-pole form with neutral left handles three-phase-plus-neutral circuits common in European and IEC distribution. The 108 mm width (12 x 9 mm pitches) fits standard enclosure cutouts. IP40 enclosure protection and IK07 impact resistance suit clean indoor panel environments.
Trip unit and coordination
The TM-D thermal-magnetic trip provides fixed thermal protection (inverse-time) and fixed magnetic instantaneous pickup. Electrical endurance is 20,000 cycles at 440 V In/2, dropping to 5,000 cycles at 690 V In. These figures govern maintenance intervals in high-cycle applications like conveyor or pump panels.
