The 50 kA interrupting rating at 240 VAC gives headroom for high-fault installations where coordination with upstream gear matters.
Rated for 240 VAC, 30 A continuous, with a K trip curve that allows magnetic trip at 8–12× rated current. The 50 kA interrupting capacity at 240 VAC covers most industrial panel fault levels. Three-pole configuration suits three-phase branch circuits or single-phase loads where common-trip is required. DIN rail mounting simplifies panel layout and replacement.
The S803U-K30 has a 50 kA interrupting rating at 240 VAC.
S803U-K30 is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.
The K trip curve provides magnetic trip at 8–12× rated current, designed for inductive loads with moderate inrush.
