- Compact, service-friendly design: Built for quick replacement in panelboards and load centers, reducing downtime during maintenance or upgrades.
- Clear electrical distribution protection: Ideal for safeguarding branch circuits and critical loads within electrical distribution networks.
Ideal use cases
- Retrofit projects where existing equipment must retain its original part number for compatibility with documentation and spare parts inventory.
- Maintenance planning for building systems, ensuring consistent protection components across service life cycles.
- Load-center and panelboard upgrades that require reliable, readily available 2-pole protection at 400 V.
- Spare-part stock for service fleets, reducing search time when a replacement is needed.
