Rated IP20 with conductors connected, so it belongs inside a sealed enclosure, not out in the open. ## Environmental & Compliance Energy limiting class 3 offers good current-limiting performance to reduce let-through energy on downstream equipment. The sealable feature allows panel builders to lock the toggle position to prevent unauthorized switching.","metaTitle":"Siemens 5SJ6220-7KS SENTRON MCB, 2P C 20 A 6 kA","metaDescription":"Siemens SENTRON 5SJ6220-7KS miniature circuit breaker, 2-pole, C-curve, 20 A, 6 kA breaking capacity per IEC/EN.
