Selection Notes

As an NA-coded device, the C080S3NAFM carries no interrupting (Icu) rating of its own, so it isolates the circuit but does not break fault current; it must be paired with separate overcurrent protection upstream or downstream. Its 800 A Ie/Ith matches the equivalent-frame NS800 circuit breakers in the same case size, so it can fill the same enclosure footprint as a maintenance isolator, bypass switch, or non-automatic main disconnect. Its 52 kA Icm short-circuit making capacity means it can be closed onto a live fault without the contacts welding shut, a property required of a switch used as a line-side or load-side disconnect rather than a simple load break switch. The 3-pole version switches the three phases only; the 4-pole version of the same case also switches the neutral.
