The combined terminal design (screw-type) accepts a single conductor per clamp; no neutral switching on this 2P unit (it switches both poles, but the neutral is not broken). The sealable cover option lets you lock the toggle position after commissioning — useful for tamper-proofing in shared-access panels. ## Regulatory and compliance notes The breaker is designed for railway applications (per) and carries the EN 60898 rating for residential/commercial use, plus overvoltage category III. Touch protection is built in (finger-safe terminals when wired). The product is classified per DIN EN 61346-2 and 81346-2 as function F (protection).","metaTitle":"Siemens 5SY4220-8CC11 SENTRON MCB, 2P D 20 A, 10 kA","metaDescription":"Siemens 5SY4220-8CC11 SENTRON miniature circuit breaker, 2-pole, D-curve, 20 A, 10 kA breaking capacity per EN 60898, 400 V AC.
