Sourcing and lifecycle
Procurement note: this is a heavy unit at 6.52 kgs, so factor that into shipping costs and handling for panel build or site delivery. Sourced to order against an RFQ; availability and current pricing confirmed at quote time.
What the ratings mean for the installation
The 1250 A continuous current rating sets the frame size for feeder and main breaker applications. This is the thermal-magnetic or electronic trip rating — verify the trip unit type and interrupt rating from the full nameplate for coordination studies.
