The 3P design with a rated current of 160 A delivers integrated three-phase protection, simplifying panel layouts and reducing installation time in factory distribution boards. This translates to faster commissioning, lower cabinet footprint, and easier spare-part stocking for industrial plants that rely on Isomax S3 configurations. With a rated operational voltage of 690 V AC and an 8 kV impulse withstand, the device offers robust surge and fault endurance, preventing nuisance trips during motor start-ups and transient events. In practice, this means fewer unplanned shutdowns and improved safety margins across high-energy drives. Release Type TadjM10 and Short-Circuit Performance Level L enable precise, reliable tripping characteristics while meeting IEC947-2 requirements. The rated ultimate short-circuit capacity varies with voltage, providing up to 20 kA at 690 V, helping protect downstream equipment. Front terminal connections facilitate straightforward installation and future maintenance, reducing assembly time in crowded switchgear. The device's compact net dimensions (178 mm x 233 mm x 0.1035 m) and 2.6 kg weight support modular upgrades and safer handling in confined spaces. Electrical durability of 10,000 cycles with a power loss of 30 W offers long life under frequent switching, reducing energy use and cooling demands in continuous operation. Combined with RoHS and WEEE compliance and Isomax S3 compatibility, these features translate to lower total cost of ownership over the equipment lifecycle.
