The Trip Curve Z trips between 2.5× and 5× rated current, designed for semiconductor and sensitive electronic loads where standard B or C curves would allow too much let-through energy. Two-pole width means it occupies two module spaces (36 mm) in the distribution board. The 40 A rating suits it for branch-circuit protection on high-current electronic loads or as a main isolator in a sub-panel feeding sensitive equipment.","metaTitle":"ABB S202P-Z40 MCB 2P Z 40A 277V AC, 10 kA","metaDescription":"ABB S202P-Z40 miniature circuit breaker, 2-pole, Trip Curve Z, 40 A, 277 V AC, 10 kA interrupting rating.
