The 6 kA breaking capacity (tested to both EN 60898 and IEC 60947-2) is adequate for residential and light commercial distribution boards where the prospective short-circuit current stays under that level. ## Physical dimensions and environment Dimensions: 90 mm height, 36 mm width (2 MW), 76 mm depth. Installation depth from the mounting surface is 70 mm. The housing is sealable, halogen-free, and silicon-free — relevant for panels in food processing or clean-room zones where outgassing is restricted. Ambient temperature range is -40 °C to +75 °C, with periodic exposure up to +55 °C at 95% humidity. The part carries a mechanical service life of 20 000 operating cycles typical.","metaTitle":"Siemens 5SJ6220-6KS SENTRON MCB, 2-Pole B 20A 6kA","metaDescription":"Siemens SENTRON 5SJ6220-6KS miniature circuit breaker, 2-pole, B-curve, 20 A, 6 kA breaking capacity per EN 60898.
