Its IEC 60898 breaking capacity is 10 kA; under UL 1077 and CSA C22.2 No. 235 it carries 5 kA — the UL figure governs installations in North American panels, while the IEC figure applies in European-distribution boards. It mounts in any position, which simplifies layout in crowded enclosures — no derating required for horizontal or inverted orientation. The combined terminal at top and bottom accepts conductors for daisy-chaining busbars, and the sealable cover allows lockout-tagout compliance on the panel door. ## Environmental and compliance profile Rated for ambient temperatures from -40 °C to 75 °C, with humidity derating per the spec: max 95% RH up to 55 °C, dropping to 35% at 75 °C. The MCB is halogen-free and silicon-free — important for clean-room or semiconductor-adjacent panels where outgassing must be controlled.","metaTitle":"Siemens 5SY4310-6CC SENTRON MCB, 3P B-10A, 10 kA","metaDescription":"Siemens 5SY4310-6CC SENTRON miniature circuit breaker, 3-pole, B-curve, 10 A, 10 kA IEC breaking capacity.
