FAQs
Yes. The 1SDA050726R1 is a three-pole fixed MCCB with front terminals designed to integrate into Isomax S4X layouts. It supports standard ABB mounting and wiring practices, and the EAN 8015644510848 along with a Minimum Order Quantity of 1 piece simplifies procurement for panel upgrades and retrofits.
The device provides 1000V rating, is three-pole, fixed with front terminals, and uses a solid-state release (AC PR 212 LSI R 250). These specs enable precise overcurrent protection, reliable tripping, and safe operation in demanding industrial power distribution and control panels.
This MCCB is well suited for industrial control panels, motor feeders, and machine power distribution in manufacturing environments. Its front-terminal design minimizes wiring effort during assembly, maintenance, and upgrades, while the 1000V rating supports higher voltage panel applications common in automation lines.
The product aligns with WEEE Category 5 for small equipment, aiding waste management compliance. It carries a 1000V, three-pole specification and uses ABB’s Isomax S4X-compatible architecture, which helps ensure compatibility with common European and global electrical standards in automated facilities.
Current-limiting and robust solid-state release reduce fault energy and arc exposure, lowering downtime and maintenance costs. Front-terminal wiring simplifies field servicing and retrofits, enabling faster project completion and longer service life for critical power distribution in high-demand automation environments.
