The 10 kA interrupting rating at 415 V AC means it can safely interrupt fault currents up to that level on a 415/240 V three-phase system or a 240 V split-phase service. Rated for multi-phase operation up to 440 V AC and single-phase up to 250 V AC, with a DC rating of 72 V maximum. The 2-pole design switches both line conductors, suitable for 2-wire single-phase or two legs of a three-phase circuit. ## Physical integration and environment Dimensions are 18 mm wide, 90 mm high, and 76 mm deep — a single 1 MW unit that clips onto standard DIN rail. This is the standard residential/commercial interrupting rating for most European distribution boards. Power loss: 2.17 W per pole in hot operating state at rated current. Mechanical service life: 10,000 operating cycles typical. This is adequate for normal switching duty in a distribution board; for frequent switching applications (e.g., as a disconnect under load), consider a contactor instead.","metaTitle":"Siemens 5SL4220-7RC SENTRON MCB, 2P C-Curve 20A 10kA","metaDescription":"Siemens SENTRON 5SL4220-7RC miniature circuit breaker, 2-pole, C-curve, 20 A, 10 kA breaking capacity per EN 60898.
