EN/IEC 60947-2 certifies it for isolation duty; you can lock it open and work downstream confident the disconnect is certified, not just mechanical. That 160 A thermal-magnetic rating governs the continuous load it carries — sized for a distribution subfeed or a large motor branch on a 400 V three-phase system. The TM-D curve gives a fixed magnetic trip threshold, so coordinate it downstream with smaller MCBs and upstream with a higher-rated main breaker. The 4-pole version switches the neutral, which matters for TN-S or TT systems where you need full isolation on all poles. At 12 module pitches (108 mm wide, 137 mm high, 80 mm deep) it fits standard panel cutouts.
Deployment context — panel integration and environment
Rated IP40 and IK07 impact resistance — suited for indoor switchboards and distribution panels where occasional tool contact or dust ingress is possible but washdown is not required. The grey RAL 7016 finish is the standard industrial enclosure colour across the ComPacT range — uniform look in multi-breaker panels.
Endurance and duty — what the cycle ratings mean
Mechanical endurance 20,000 cycles; electrical endurance 20,000 cycles at 440 V at rated current, halving to 10,000 cycles at 440 V at In/2. That means it handles frequent switching — say a weekly disconnect on a process line — for decades before the mechanism wears. Utilisation category A means it's not intended for frequent motor starting under load; use a contactor for that duty.
