Feature → Business Impact → Application: Rated Current (In) of 320 A enables robust protection for demanding DC loads in automation panels, reducing fault propagation and associated downtime in manufacturing lines. In practice, this supports consistent uptime in battery storage and drive systems, while enabling compact panel designs without compromising safety. Feature → Business Impact → Application: Rated Operational Voltage (750 V DC) provides a wide operating window for modern DC distribution networks, enabling safe integration with high-voltage DC supplies and renewable energy interfaces. This is particularly valuable in microgrid or data-center style industrial environments where space and efficiency matter. Feature → Business Impact → Application: Short-Circuit Performance Level X with Rated Short-Circuit and Ultimate Short-Circuit Capacities up to 100 kA in series configurations ensures rapid fault isolation during peak current events, improving system resilience in motor control centers and feeder panels. Feature → Business Impact → Application: Power Loss of 16.9 W per pole delivers lower thermal rise and reduced cooling requirements, translating to energy efficiency gains and smaller auxiliary cooling budgets in compact MCCs. Feature → Business Impact → Application: Mechanical Durability of 20,000 cycles provides a long service life under frequent switching, lowering maintenance costs and replacement risk in critical automation loops. Feature → Business Impact → Application: Recyclability and EcoSolutions support for end-of-life planning (EN45555, EPD, RoHS/REACH) reduce total cost of ownership by simplifying compliance reporting and waste management for large installations. Feature → Business Impact → Application: Fixed Circuit-Breaker terminals with 3P configuration ensure straightforward panel installation and reliable, vibration-resistant connections in demanding industrial environments, reducing commissioning time and installation errors.

FAQs
The device uses fixed circuit-breaker terminals designed for panel mounting rather than DIN rail. For best results, install in appropriately rated enclosures or switchgear frames with correct clearance and busbar spacing. Ensure torque values and conductor sizing meet the 320 A rating and 1000 V insulation requirements.
Key specs include 320 A rated current, 750 V DC rated operational voltage, 1000 V insulation voltage, and Ics/Icu up to 100 kA in series configurations. It conforms to IEC 60947-2 and supports a short-circuit performance level of X, ensuring rapid fault isolation in DC power circuits.
Yes. With 3P configuration, 320 A rating, and 750 V DC operation, it is well-suited for battery energy storage, motor control centers, and DC distribution panels where fast protection and reliable trip curves are critical for uptime and safety.
It carries IEC 60947-2 compliance, CE conformity via EC Declaration of Conformity, and EN45555 recyclability with an Environmental Product Declaration. RoHS/REACH declarations are also available, helping meet regulatory and sustainability requirements in global shipments.
The unit provides up to 20,000 mechanical cycles, reducing replacement frequency and maintenance costs. Its ECO solutions and recyclability features simplify end-of-life planning, while compact dimensions and low per-pole power loss help minimize cooling and enclosure space, improving total cost of ownership.
