Breaking capacity is 187 kA at 240 V AC, dropping to 121 kA at 415 V and 75.6 kA at 440 V — still well above typical fault levels for most commercial and industrial services. The TM220 overcurrent release combines a thermal-magnetic trip with fixed settings — no adjustment dials, which simplifies specification but means you select the exact amp rating at ordering. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep; it fits a standard 3-pole MCCB footprint on DIN rail or panel-mount.","metaTitle":"Siemens 3VA1112-5EE32-0AA0 SENTRON MCCB, 125 A, 3-Pole, TM22","metaDescription":"Siemens 3VA1112-5EE32-0AA0 SENTRON molded case circuit breaker, 125 A rated at 40 °C, 3-pole, TM220 release, 187 kA at 240 V.
