Verified configuration
The official product page states 630 A continuous current, 21 kA short-time withstand for 1 second and 50/60 Hz operation. It also identifies an AFLR internal-arc classification, which must be read with the exact test current, duration and accessibility conditions.
Engineering significance
The product adds a Saudi-manufactured dry-air RMU to the supplier landscape and is relevant to localisation, regional service and fluorinated-gas-free procurement strategies.
Specification caution
Verify functional units, circuit-breaker or switch-fuse arrangement, cable interfaces, internal-arc test parameters, automation, ambient derating and certification. Project references published by alfanar remain manufacturer case-study claims.
