Single-phase rating is 250 V. For DC circuits, the maximum rated voltage is 72 V — this breaker is not a primary choice for higher-voltage DC bus protection. The 2-pole design switches both phase conductors simultaneously; there is no integrated neutral switching. IP20 protection applies only with connected conductors; the terminals are not touch-protected when unmated. ## Deployment context Snap-on mounting to DIN rail (35 mm) in any position. The 36 mm width occupies two modular width units on the rail. The retail line designation means this breaker is intended for distribution boards in retail, commercial, and light industrial settings — not for heavy industrial motor control centers where higher SCCR or different trip coordination may be required. Sealable design allows the breaker to be locked in the OFF position for lockout/tagout procedures.","metaTitle":"Siemens 5SJ6220-7RC SENTRON MCB, 2P, 20A, C-Curve, 6kA","metaDescription":"Siemens SENTRON 5SJ6220-7RC miniature circuit breaker, 2-pole, 20 A, C characteristic, 6 kA breaking capacity per EN 60898.
