Feature → Business Impact → Application: Magnetic only protection (K) delivers fast, magnetic tripping for short‑circuit faults, reducing fault duration and equipment damage while enabling safer start‑ups in motor feeders and distribution panels. Application: ideal for industrial machinery and process lines where sudden surges must be contained without nuisance trips. Feature → Business Impact → Application: 3‑pole design at 32 A and 440 V AC supports balanced three‑phase loads with streamlined wiring, improving panel density and simplifying commissioning. Application: suitable for MCCs and dashboard breakers in manufacturing cells that require reliable three‑phase protection. Feature → Business Impact → Application: Rated short‑circuit capacity of 10 kA (400 V) and rated ultimate capacity up to 10 kA (440 V) provide robust fault clearance, reducing downtime and protecting downstream devices. Application: critical in high‑load conveyors, pumps, and presses where fault current can spike. Feature → Business Impact → Application: Flexible 1…25 mm² and rigid 1…35 mm² connection options shorten install time and lower wiring errors, boosting installation efficiency and traceability. Application: ideal for retrofit projects and new builds where wiring flexibility accelerates delivery. Feature → Business Impact → Application: IP20 protection and a compact footprint enable safe operation inside standard enclosures, supporting compact switchgear designs and minimizing enclosure costs. Application: great for control panels in harsh factory environments. Feature → Business Impact → Application: Energy Limiting Class 3 and low power loss per pole (1.7 W) reduce energy waste over lifecycle and improve overall system efficiency. Application: beneficial for energy‑aware facilities seeking lower running costs over time.
