At 415 V this breaker handles fault currents up to 154 kA — enough for most industrial main switchboards and large sub-distribution boards where high available fault current is a concern. Above that, the TM240 release derates: 194 A at 55 °C, 188 A at 60 °C, 182 A at 65 °C, 176 A at 70 °C. Dimensions are 140 mm wide × 158 mm high × 70 mm deep. No auxiliary contacts or communication module are fitted on this variant. The UVR coil is the only auxiliary. If you need remote status or shunt trip, you'll add the external accessory block separately. The TM240 release is a thermal-magnetic design with a fixed thermal curve for overload and magnetic for short-circuit. No electronic adjustment or zone-selective interlocking. The storage limit matters for spares kept in unheated warehouses — fine down to -40 °C, which covers most climates.","metaTitle":"Siemens 3VA1220-6EF42-0BA0 SENTRON MCCB, 200 A, 4-Pole, TM24","metaDescription":"Siemens SENTRON 3VA1220-6EF42-0BA0 molded case circuit breaker, 200 A rated continuous current, 4-pole, TM240 release.
