That means this breaker can be installed upstream of a high-fault transformer or busway without worrying about cascading failure — the SCCR is high enough to let it clear a bolted fault before the arc flash energy climbs. The TM210 overcurrent release is a thermal-magnetic trip unit — thermal for overload protection, magnetic for short-circuit. It's a fixed-trip breaker for straightforward line protection where you don't need selectivity tuning.","metaTitle":"Siemens 3VA1120-6ED46-0AA0 SENTRON MCCB, 4P, 20A, 220kA","metaDescription":"Siemens 3VA1120-6ED46-0AA0 SENTRON molded case circuit breaker, 4 poles, 20 A rated at 40 °C, 220 kA breaking capacity at 240 V.
