Rated for 277 VAC (line-to-neutral on a 480Y/277 V system) and carries a 6 kA interrupting rating at that voltage, so it safely clears faults up to 6 kA without upstream cascading — typical for branch-circuit protection in commercial panels. Mounts on standard DIN rail, drops into the same footprint as other System pro M compact breakers — no panel rework if swapping from a C-curve sibling. ## How it sits against the closest sibling The S202M-C16 shares the same 2-pole DIN-rail footprint and 16 A rating but uses a Trip Curve C (5 to 10 times In), which handles moderate inrush from small motors or capacitive loads. If your BOM specifies Curve B for resistive loads, the C-curve version may nuisance-trip on startup — stick with the S202-B16 unless the load profile changes.","metaTitle":"S202-B16 Miniature Circuit Breaker, 2P, 16A, Trip Curve B, 6","metaDescription":"S202-B16 miniature circuit breaker, 2-pole, 16 A, Trip Curve B, 6 kA interrupting rating at 277 VAC.
