The S801S-D16 is a 1-pole miniature circuit breaker rated 16 A with Trip Curve D characteristic, meaning it tolerates the high inrush currents typical of motor and transformer loads — the magnetic trip threshold sits at 10 to 20 times rated current, so it holds through startup spikes that would nuisance-trip a Curve C or B breaker on the same circuit. 50 kA interrupting capacity at 400/690 VAC. Rated operational voltage covers 400/690 VAC and 125 VDC, with a frequency range of 50/60 Hz.
DIN Rail Integration — Panel Fit
The single-pole footprint takes one 18 mm module width — plan for 18 mm per pole in the enclosure layout. No side-by-side ganging kit needed for multi-pole assembly; the breaker clips directly to adjacent units. Thermal tripping mechanism handles overload protection; electromechanical short-circuit trip handles faults. Both mechanisms are self-powered — no auxiliary supply needed for the trip function.
