It snaps onto DIN rail for panel integration. ## What Trip Curve Z means for your circuit Trip Curve Z provides the shortest magnetic trip delay of the standard curves, typically tripping within 2–3× rated current. This makes the S202-Z10 suited for protecting semiconductor devices, sensitive electronics, and control transformers where even brief overcurrents can damage components. It is not the general-purpose choice for motor or distribution branch circuits — those call for Curve C or D. The 10 A continuous rating and 6 kA interrupting rating at 277 VAC mean it clears faults up to 6,000 A on a 277 V line-to-neutral circuit, common in 480Y/277 V commercial panels.","metaTitle":"ABB S202-Z10 MCB 2P Z 10A, 6 kA, 277 VAC","metaDescription":"ABB S202-Z10 miniature circuit breaker, 2-pole, Trip Curve Z, 10 A, 6 kA interrupting at 277 VAC.
